Top email marketing examples by category & why they work

Ready to explore the best email examples from popular brands? Here are the ones that caught our attention:

1. Welcome messages

When someone subscribes to your newsletter, creates an account, or places an order for the first time, your welcome message marks the beginning of your relationship. That first impression should feel warm, inviting, and intentional.

These campaigns help new subscribers and customers understand who you are, what you offer, and what to expect next, whether that’s weekly updates or occasional offers.

Successful welcome email examples guide readers toward a simple next step rather than asking too much from them at once. For example, if you want to share your brand story, add a single CTA that encourages subscribers to learn more. 

Before anything, welcome emails set the tone for the relationship ahead. Clear expectations, simple messaging, and low-pressure CTAs help you build trust from the first touchpoint.

Ambassade Hotel’s welcome email

Subject line: Welcome to the Ambassade Hotel community

The image is a welcome email by Ambassade Hotel showing the hotel entrance, the exterior facade, and a boutique hotel bedroom. There's also a CTA prompting subscribers to discover reasons to visit.

What makes it effective:

  • The elegant design matches the hotel’s artistic vibe.
  • Mentioning the family-run history gives the email a warmer tone.
  • The mix of cultural experiences, a promise of comfort, and a sustainability certificate speaks to different types of travelers.
  • The CTA prompts readers to discover the hotel instead of pushing readers to book right away.

Saatva’s welcome discount

Subject line: Welcome to Better Sleep!

A screenshot of a welcome email campaign with a smiling couple lying on a Saatva mattress and popular product categories.

What makes it effective:

  • The first-time discount gives recipients a tangible reason to start shopping.
  • The CTA is solution-oriented, focusing on the benefit readers will reap by clicking rather than prompting  them to “Buy Now.”
  • Featuring popular product categories lets people discover secondary products if they aren’t ready to buy a mattress yet.
  • The chat and phone support options simplify the process for hesitant buyers.

2. Email newsletters

Newsletters are a communication goldmine because they are a consistent way to provide value on a monthly, bi-weekly, or weekly basis. 

With them, you can share various resources that position your business as an industry leader that stays on top of the latest developments. But you shouldn’t only rely on your own business updates, blog content, or reports. Curating insights from niche sites gives your subscribers a broader perspective.

These emails can also build excitement around product launches, exclusive content, and upcoming events before the official announcement.

What makes email newsletters unique is that they offer subscribers a much-needed break from constant promotions. Since their focus isn’t always on selling, readers are more likely to look forward to each new roundup.

Asana’s sneak-peek newsletter

Subject line: Coming soon! Organize My Tasks your way

A screenshot of Asana's newsletter showing the user interface with 'My Tasks' feature and what this addition offers.
In Asana’s newsletter, the visual teaser of the new functionality stands out against the clean design. Image source: Really Good Emails

What makes it effective:

  • From the email subject line to the copy, the email keeps the focus on customer experience.
  • They frame feature updates around user feedback, making product development feel like a response to their needs.
  • Instead of overexplaining every new capability, the campaign sticks to a short, easy-to-scan list of benefits.
  • The email CTA clearly explains what readers will gain, which fits the educational angle of the message.

Gindo’s Spice of Life newsletter

This image is a Labor Day promotional newsletter showing bottles of hot sauce and food cooking on a grill by Gindo's Spice of Life alongside a CTA to purchase the products.
Constant Contact’s customer Gindo’s Spice of Life used their newsletter to promote a Buy 2 Get 1 Free offer for Labor Day. Image source: Constant Contact

What makes it effective:

  • The appetizing image above the fold instantly draws attention to the deal.
  • Recommendations like drizzling the sauces over cheese boards spark culinary inspiration.
  • They break up blocks of text and product categories using emojis, bold text, and white space.
  • Clear redemption instructions placed right before the CTA make the offer easy to claim.

New York Magazine’s app launch announcement email

Subject line: Introducing “Your New York”

A screenshot of an announcement email from New York Magazine showing images of the mobile app interface alongside colorful illustrations.
This email newsletter example by New York Magazine introduces their app and encourages readers to download it. Image source: Really Good Emails

What makes it effective:

  • The unique typography makes the campaign instantly recognizable while giving it an editorial look.
  • Through the colorful illustrations, they position the app as a helpful tool with personalized recommendations.
  • The red arrows and thin divider lines used in the assets list bring to mind a newspaper structure rather than a product description.
  • They avoid adding multiple CTAs, letting the app be the one and only newsletter star.  

3. Lead nurturing email examples

If five people sign up for a gym membership, will all of them start working out the next day? Probably not. Some will book a session with a trainer, others will check the space before coming back the following week, and a few may never step foot in the gym at all. 

Likewise, not all people on your list are ready to purchase right after creating an account or subscribing to your emails. Lead nurturing emails take on that “training” role, helping them understand your core offerings over time. 

These campaigns can include:

  • Product tutorials and demos
  • Customer stories and case studies
  • Comparison guides
  • Free tools 
  • Industry tips and practical advice

That said, avoid overwhelming subscribers with long descriptions covering every product or feature as displayed on your website. Address one pain point per email, linking to blog posts or product pages for those who want more details.

Bite’s product education email

Subject line: “Why should I switch?

This image shows a woman holding a toothpaste tablet in her mouth, a list of the products' benefits, and a CTA encouraging readers to buy.
This product education email example by Bite explains why subscribers should switch to the brand’s plastic-free products. Image source: Bite

What makes it effective:

  • The company logo and slogan at the top reinforce the brand’s environmental mission.
  • The hero image shows how to use the product to clear up potential confusion.
  • They include two side-by-side lists to showcase what consumers avoid and what they gain by switching.
  • The customer review citing a professional validates the product’s effectiveness.

Casper’s lead nurturing email

Subject line: Struggling to get shut-eye? ?

This image is a lead nurturing email example by Casper with a woman sleeping and graphic illustrations for sleep-related blog posts.
Casper’s lead nurturing email provides helpful content for sleep-deprived customers. Image source: Really Good Emails

What makes it effective:

  • The time-sensitive promo banner at the top catches the eye without overpowering the main message.
  • The short and crisp copy naturally guides readers toward the CTA.
  • Additional resources appeal to different interests, including a buying guide and sleep tips.
  • The brand invites readers to subscribe to SMS updates through a dedicated footer section.

4. Promotional campaigns

These campaigns are the cornerstone of any email marketing strategy. Still, excessive promotions tend to cause subscriber fatigue. While keeping your audience informed about discounts and launches is important, strategic delivery matters just as much.

Effective promotional emails include tailored recommendations and offers matching customers’ past purchases, interests, and browsing behavior. A sense of exclusivity also makes your suggestions feel more relevant and less intrusive.

High-quality product images or videos help potential customers picture themselves using the product. A touch of urgency can help, too; emphasis on a touch. Stacking oversized discounts, countdown timers, and all-caps phrases like “SELLING OUT FAST” in the same email may scare people away, or worse, trigger spam filters.

Starbuck’s limited-time deal

Subject line: Friday = 50% off your drink ?

This image is an email by Starbucks promoting a 50% discount on specific days. It shows a tall iced yellow drink and three colorful cold beverages.
This email marketing campaign by Starbucks promotes a 50% discount on drinks on specific days. Image source: Really Good Emails

What makes it effective:

  • Recipients can tell what’s in it for them and when they can get it right from the subject line.
  • The blue headline against the softer background colors makes the offer pop.
  • The compelling images of colorful drinks are so vivid you almost feel thirsty. 
  • The “See you Friday” CTA reads more like a friendly invite than a sales push.

Notebook Therapy’s product launch campaign

Subject line: Free cat printables!

A screenshot of a promotional email by Notebook Therapy prompting subscribers to download free daily and weekly planner templates and purchase a limited-edition journal.
In their promotional email example, Notebook Therapy uses a new product launch to give subscribers a small gift. Image source: Notebook Therapy

What makes it effective:

  • Providing value with free samples before introducing a promotion is an excellent way to show you’re not just going after revenue.
  • The email smoothly transitions from the freebie to a cross-sell recommendation.
  • The elegant calligraphy fonts and illustrated cats and flowers create an aesthetically pleasing email design.

5. Transactional messages

Businesses often treat transactional emails as operational messages, but they can do more. They acknowledge the subscriber’s action, letting them know everything worked as it should. This, in turn, builds trust and reassures customers right when they’re paying attention.

For this to happen, transactional emails don’t have to follow the standard “You did [Action], we confirmed it” format.

 To move beyond that, you can:

  • Add simple onboarding steps to order confirmation emails to encourage product adoption.
  • Use delivery notification campaigns to request feedback or reviews.
  • Invite customers to join your loyalty program after a purchase or signup.
  • Share educational resources in service upgrade confirmations.
  • Turn password reset emails into quick account security reminders.

Vacasa’s booking confirmation email

Subject line: Checking into your Vacasa home, Desert Dream

An image of a booking confirmation email example by Vacasa with a bright living room of a rental house and check-in details.
Vacasa’s transactional email example shares practical information before arrival to help guests settle in smoothly. Image source: Really Good Emails

What makes it effective:

  • The clean, structured design with easy-to-digest instructions offers a great experience before the actual stay.
  • Each tip is in chronological order, matching the steps guests take upon arrival.
  • Important details like the lockbox code and address stand out through bold formatting.
  • The troubleshooting checklist at the end answers common check-in questions before guests ask for support.

Wayfair’s reset password campaign

Subject line: Reset Your Password

A screenshot of an email marketing example by Wayfair with a password reset CTA alongside images of a stainless steel kitchen sink and glass storage containers.
Besides the password reset CTA and instructions, Wayfair’s email also includes limited-time promotions. Image source: Really Good Emails

What makes it effective:

  • The clear CTA at the top of the email ensures readers don’t miss the required step.
  • The header links direct subscribers to popular product categories on their website.
  • Secondary CTAs promote gift cards and limited-time deals without distracting readers from the main action.

6. Post-purchase campaigns

Your relationship with your customers doesn’t end once the purchase is complete or the order is delivered. After that first transaction, you can prepare the ground for more to come. 

With the right post-purchase email, businesses are likely to turn casual shoppers into repeat customers. A thoughtful follow-up puts the customer at the center and deepens the relationship beyond the checkout page.

A simple approach is helping people get the most out of what they just bought. This might translate into usage instructions and maintenance tips like how to avoid mistakes that shorten an appliance’s lifespan.

A week or so after purchase is also a great time to ask for feedback or a review, while their experience is still fresh. Even if the response isn’t enthusiastic, it can help you detect friction points to fix them down the line.

Last but not least, you can use these email campaigns to deliver upsell and cross-sell recommendations that improve or expand how customers use the product. To encourage a second order, you can offer an incentive like a small discount on a related item. 

Pulp & Press’ post-purchase email

Subject line: It’s time to get cleanse-ready!

A screenshot of a post-purchase email by Pulp & Press showing a grid of bottled juices and a list of healthy tip illustrations.
In this post-purchase email example, Pulp & Press delivers self-care tips so customers can maximize the impact of the purchased products. Image source: Really Good Emails

What makes it effective:

  • The timing before delivery helps set expectations and prepare customers for what’s next.
  • The encouraging headline builds self-confidence, empowering customers to begin their self-care journey.
  • The email shares three practical tips recipients can easily put into practice.
  • Inviting customers to share their experience encourages further engagement while offering the brand valuable user-generated content.

Patagonia’s follow-up campaign

Subject line: It’s good to wash your shells

This image is an educational newsletter email by Patagonia showing an alpine climber on a rocky cliff side and a rain jacket being loaded into a washing machine by Patagonia. They also include two CTAs to read the care guide or shop rain gear.
This follow-up email by Patagonia focuses on care instructions to help customers keep their shells as good as new. Image source: Patagonia

What makes it effective:

  • They cleverly link the need for frequent cleaning to the product’s sustainable ingredients.
  • The clear icon instructions turn the care process into a simple checklist.
  • Subscribers can either read the care guide or watch a quick video to learn how to prolong the life of their jackets.

Forever 21 cross-sell email

Subject line: Spice up your last haul with something new

This is a screenshot of a promotion email example by Forever 21 showing a person holding a yellow shopping bag and a collection of women's apparel items.
Forever 21 sends this cross-sell email to suggest products based on subscribers’ buying and browsing history. Image source: Really Good Emails

What makes it effective:

  • The subject line clearly ties the campaign to a recent purchase, which improves relevance.
  • The lighthearted vibe and conversational tone matches the brand’s style.
  • They use casual language and short copy to keep the focus on the products rather than the sales pitch.
  • They target recipients with recommendations tailored to their past behavior to boost conversions.

7. Seasonal campaigns

Peak buying periods like Christmas, Black Friday, and Valentine’s allow brands to tap into seasonal intent with timely content. These emails can provide quick solutions instead of waiting for your target audience to search for answers on their own.

Here are a few ways you can use seasonal email marketing:

  • Promoting a limited-edition product or collection
  • Announcing a time-sensitive deal or sale
  • Putting together gift guides 
  • Offering season or holiday-specific tips

Some businesses miss out on seasonal opportunities because they can’t find a way to tie their products or services to specific times of the year. But chances are there are relevant occasions to target subscribers based on your industry and their interests.

Take nonprofit email marketing, for example. Christmas isn’t the only holiday season when people are willing to give. You can also send campaigns on Earth Day (if you support green initiatives) or Giving Tuesday, like in the following email campaign.

Austin Ekeler Foundation’s fundraising email

This image is a Giving Tuesday fundraising email  by the Austin Ekeler Foundation showing Austin Ekeler with a group of students. The copy explains new initiative while the CTA encourages readers to donate.

What makes it effective:

  • The first-person narrative and handwritten signature make the email feel like a personal note from the founder.
  • Linking donations to a specific goal the founder stands for helps readers visualize the impact of their contribution.
  • By highlighting the outcomes of their past efforts, the brand establishes credibility and shows that this campaign is part of an ongoing initiative.
  • The content sticks to just a few elements: a relevant image, on-point copy, and an actionable CTA.

Penguin Random House’s World Emoji Day

Subject line: Guess the Book Titles Based on Emojis!

This image is a World Emoji Day newsletter showing an "Emoji Story Time" title graphic and emoji book riddles by Penguin Random House. They also invite subscribers to guess the titles and click to see if they were right.

What makes it effective:

  • The brand translates famous book titles into emojis and invites subscribers into a fun trivia game.
  • They add an emoji sequence in bubble format to mimic a text message.
  • Keeping the copy brief and letting emojis take over ensure the email is easy-to-digest and engaging.

Day Out’s fall campaign

Subject line: New Fall Breakfast Ideas Inside! ??

Besides just promoting the products, Day Out’s email shares a creative recipe that subscribers can make with them. Image source: Really Good Emails

What makes it effective:

  • The brand prompts recipients to open by mentioning there are fall breakfast recipes inside.
  • Giving recipients the opportunity to read the recipe without leaving the email eliminates the need for another click.
  • Adding the conversion point under the recipe makes the transaction feel like the next logical step.
  • They use colors and wavy lines to keep sections organized and distinct.

8. Abandoned cart campaigns

According to a recent ecommerce report, the cart abandonment rate reached 71.72% in the first half of 2025. Simply put, 7 out of 10 visitors are likely to leave a website without completing checkout.

Abandoned cart emails are automatically sent when visitors exit your store with items in their cart without buying. They act as gentle reminders of the unfinished action, which is why they’re such a valuable tool for recovering lost revenue.

With these messages, you want to bring people back to your store so they can pick up where they left off. It’s essential to send the first email immediately after the abandonment when the products are still top of mind.

When it comes to the email content, consider these tactics:

  • Add high-quality product images to help customers remember the items and prompt them to come back for them.
  • Include customer reviews or star ratings to support your claims with real feedback from their peers.
  • Instead of guilting subscribers, bring humor and creativity into the mix, for example by blaming external factors like their internet connection in the subject line or copy: “Did your Wi-Fi take the day off?”
  • Offer an incentive as a nudge to complete the purchase, such as a promo code, free shipping, or loyalty points.

Little Beast’s cart abandonment email

Subject line: Special offer – 15% Off

A screenshot of Little Beast's cart abandonment email showing a small dog wearing a blue checkered sweater and several colorful pet sweaters paired with customer reviews.

What makes it effective:

  • Adding an image of a cute dog wearing a similar product helps pet owners picture their little friend with it.
  • The brand uses urgent copy and bold text to highlight the limited-time offer.
  • The customer reviews section adds credibility, emphasizing benefits like product quality and fit.

Keeps’ abandoned cart email with discount

Subject line: That Piece You Loved?

This abandoned cart email example by Keeps shows a ca wooden headboard and nightstand alongside minimalist solid oak bed frames and corresponding purchase CTAs.
Keeps’ abandoned cart email showcases the products while encouraging conversions with a generous discount. Image source: Really Good Emails

What makes it effective:

  • They cleverly shift the focus from what customers didn’t do to what they can get now.
  • The email copy addresses several buyer concerns at once: material quality, product longevity, and cost-related factors such as discounts and free shipping.
  • They highlight the 25% discount in different components, such as the headline and CTAs, so subscribers can’t miss it. 

9. Re-engagement campaigns

Re-engagement emails are designed to rekindle the connection between your brand and inactive subscribers or customers.

You can start by giving them a tangible reason to return. An exclusive resource, a unique discount code, or a free sample are only some effective ideas. A/B testing allows you to experiment with different incentives and identify the ones that work. 

What about the tone? While it’s important to keep your brand voice, there’s nothing wrong with trying something new. Some brands get playful, borrowing dating-inspired language like “Was it something we said?” Others take a passive-aggressive approach when highlighting the benefits lapsed customers are missing out on.

If you want to play it safe, stick to reminding subscribers why they used to interact with your brand. Also, let them know what’s new to reignite their interest. You can ask them why they’re pulling away as long as you make the request polite and the feedback process quick.

Netflix’s re-engagement email 

Subject line: Don’t forget to finish 1899

This screenshot of a re-engagement email by Netflix with an image and video thumbnail from the series "1899", plus recommended show thumbnails alongside CTAs for both options.
In this re-engagement email example, Netflix targets recipients with tailored TV show recommendations. Image source: Netflix

What makes it effective:

  • They jog the subscriber’s memory right from the subject line by mentioning the TV show.
  • The brand embeds a video of the last viewed episode, offering users a direct way to pick up exactly where they left off.
  • They take personalization seriously, offering tailored suggestions across different categories based on the recipient’s watching and browsing behavior.

Airtable’s win-back email

Subject line: Your workflows miss you

This image is a re-engagement email by Airtable showing a desktop monitor that displays a product management interface. The copy prompts recipients to explore what's new in the platform.
Airtable’s win-back campaign focuses on the improvements made during subscribers’ inactivity period. Image source: Really Good Emails

What makes it effective:

  • Inviting inactive users to “step back in” feels like a welcoming nudge rather than a guilt trip to come back.
  • They highlight the ways in which the platform has improved, giving subscribers several reasons to return and benefit from the updates.
  • They keep things simple through a minimalist email design and concise copy.
  • Visual cues help separate the primary action (logging in) from the secondary CTA (exploring updates).

10. Milestone emails

Who doesn’t love a nice “kudos” for their efforts or a warm birthday wish? Milestone emails help you celebrate subscribers’ special moments within the customer journey. The most common are birthdays, brand anniversaries, or reaching a certain status or achievement with your products or services.

Now, most people expect a little treat when they achieve something, right? So, consider giving your target audience a free item with their next order or a free month on their subscription. Alternatively, include customers in your brand anniversary by sharing a limited-time discount on your best sellers or their own favorites.

With a little help from your email marketing platform and CRM, you can make your milestone emails more personal. 

Use dynamic content to display different details that reflect the subscriber’s journey with your brand. Some of them include:

  • The date they signed up or created an account
  • The number of orders they’ve made
  • Specific milestones they’ve hit along the way
  • Their current status and what to expect next 

Teachable’s 10th anniversary email

Subject line: ? It’s our birthday…

A screenshot of Teachable's anniversary email showing a large 3D number 10 that represents the platform's age along with festive confetti. There's also a ten-dollar-off discount graphic that subscribers will get if they click the CTA.

What makes it effective:

  • From the cake emoji in the subject line to the copy and visuals, this email example is all about celebrating.
  • They put customers at the heart of their success, recognizing their contribution and rewarding it with a reverse birthday gift.
  • The story of the company’s expansion serves as a low-pressure way to remind users of the various learning options available.
  • Tying the brand’s anniversary to the user’s growth turns the plan upgrade into a shared achievement.

Duolingo’s user progress update

Subject line: ? Duo sees your progress in Spanish!

An image of a weekly progress email by Duolingo showing an illustration of their owl mascot, a daily streak tracking chart, language learning statistics, and a CTA prompting the subscriber to keep learning.
Duolingo sends weekly updates like this to confirm users about their learning progress. Image source: Duolingo

What makes it effective:

  • The persuasive copy and CTAs awaken the recipient’s competitive drive and encourage them to maintain their streak.
  • The weekly calendar tracker and list of metrics helps users track their progress right away.
  • They keep design elements and text to a minimum so subscribers can focus on their activity digest and taking action.

11. Reminder emails

Reminder emails keep subscribers updated about specific actions you want them to take. Here are some examples: 

  • Renewing a subscription
  • Claiming an exclusive offer or discount
  • Registering for an event or webinar
  • Updating personal details or content preferences
  • Sharing check-in or checkout details 

Email automation allows you to target recipients at the right time with the right suggestions based on their browsing and buying habits. 

For example, purchase frequency and product lifespan data help you set up replenishment emails that arrive one or two weeks before customers run low on the product or subscription.

Another example are back-in-stock emails, automatically notifying subscribers when an item they’ve recently viewed or wishlisted becomes available again. 

Whatever the case, your reminder emails should feel like a friendly tap on the shoulder, not a warning signal. Also, make sure you provide all the key information so subscribers can easily understand what your campaign is about and what to do next. 

Better Booch’s back-in-stock email

Subject line: Back in Stock On All Your Favorites

An image of a Better Booch back-in-stock promotional email showing a collection of canned kombucha flavors and an Island Hopper kombucha can paired with a customer review and a purchase CTA.

What makes it effective:

  • The “back-in-stock” signals used both in the email subject line and header capture attention from the start.
  • They ensure the perfect combo of savory ingredients and wellness benefits to convince subscribers to reorder. 
  • They focus on a single product, letting subscribers discover more once they click on the CTA.
  • Pairing the product with a five-star enthusiastic customer review offers word-of-mouth validation.

Headspace’s event reminder email

Subject line: See you tomorrow

A screenshot of a reminder email by Headspace for their World Mental Health Day live meditation with a illustration of a smiling planet Earth. The email invites recipients to register through an actionable CTA.

What makes it effective:

  • The emotion-focused headline adds a human touch, differentiating the email from promotional event invites.
  • They stick to a single objective with a reader-friendly design and clear instructions on what attendees can expect.
  • They place the CTA above and below the fold to ensure readers can spot it, even if they don’t scroll to the bottom.
  • The casual suggestion to “invite a buddy or two” is a smart way to boost attendance without sounding pushy.

12. Social proof emails

The reason social proof is so important is that your customers are often the most authentic advocates of your brand. As a result, their peers are more likely to trust their claims compared to those coming from your marketing or sales teams.

When loyal customers share their positive experience with your products or services, other consumers can connect your offerings with real-world results. 

An effective way to have people talk about your value proposition is through video testimonials, which rank as the most popular type of video content among small businesses, at 27%. That’s because they allow viewers to connect the story to a real person with similar pain points, making outcomes feel relatable.

While you can incorporate customer testimonials, reviews, and customer success stories in almost every email, they’re a great fit for promotional campaigns, especially product launches. You can also send them as standalone campaigns, like in the example below.

Magic Spoon Cereal’s email with funny reviews

Subject line: “An acid trip in a bowl” and other weird reviews

The image shows an email example by Magic Spoon Cereal featuring funny reviews, floating loop cereal pieces, and a CTA inviting them to find their own favorite one.

What makes it effective:

  • Including a quote fragment in the subject line hints at the humorous reviews inside, which is a great way to increase open rates.
  • They feature the weirdest quotes and highlight the funniest punchlines in bold to stand out from typical testimonials. 
  • They use bold-colored blocks to guide the reader’s eye through different reviews.
  • Encouraging recipients to “find some magic” instead of shopping matches the overall relaxed tone of the campaign.

Allbirds social proof email

Subject line: The Glowing Reviews Don’t Lie ?

This image is a promotional product email by Allbirds showing a person's legs in the air wearing white knit sneakers and two CTAs prompting subscribers to browse womens' and mens' collections. There's also a side-profile view of a single sneaker and 5-star customer reviews.
In this promotional email, Allbirds includes a high-quality product image and five-star reviews to support it. Image source: Allbirds

What makes it effective:

  • The image at the top puts the product front and center while adding a modern aesthetic to the section.
  • They place two CTAs side by side so women and men can shop for the corresponding product in one click.
  • Customer reviews praise both the product’s comfort and style, catering to customers who want to combine these qualities.
  • They use witty, confident language to build on the power of social proof and ease remaining doubts. 

13. Loyalty campaigns

Your loyal customers deserve to feel valued. When you appreciate and reward them, they’re more likely to stick with your brand and make repeat purchases. What’s more, these satisfied buyers can spread the word about your products with minimum effort on your side.

The most common approach is to set up a customer loyalty program where people get rewarded for brand interactions like purchasing, downloading your app, or leaving a review. 

With loyalty email marketing campaigns, you can keep loyal customers up-to-date and engaged. Here are some use cases:

  • Inform them about expiring points
  • Encourage loyalty members to redeem rewards
  • Notify them about program changes, such as new perks
  • Ask customers to refer a friend
  • Celebrate milestones like hitting a new loyalty status
  • Announce member-only events

Southwest Airlines welcome email

Subject line: Welcome to Rapid Rewards

This image is a loyalty program welcome email by Southwest Airlines showing people carrying surfboards on a beach alongside a list of perks and a CTA to learn more. There's also an image of a tablet displaying an account profile page while the footer displays more options to connect.
This loyalty email example from Southwest Airlines welcomes new members and guides them through the next steps. Image source: Really Good Emails

What makes it effective:

  • Leading the email with the core program perks instantly reassures new members of the program’s value.
  • They replace the common choice of an airplane cabin image with a relaxing lifestyle one that connects the reward system to fun getaways.

How to build an effective email marketing campaign

Now it’s time to prioritize the email marketing campaigns that match your goals and your audience’s needs. Regardless of your experience and resources, you need to take certain steps to ensure your strategy is on the right path.

  • Use pre-designed email templates: A recent Constant Contact report revealed that email templates are the most essential feature of an email service for 54% of ecommerce businesses with fewer than 10 employees. That’s because they serve as a great campaign foundation, helping you create professional emails with a consistent look in minutes, even without design experience or a dedicated team.
  • Build your list the right way: Set up a double opt-in process so every contact you add to your list confirms they want to receive your emails. This is to ensure compliance with email regulations like GDPR and an engaged subscriber case. To sweeten the deal, you can use a lead magnet like a free report to set the tone for future, value-driven communications.
  • Prioritize personalization: Generic emails sent to the entire list belong in the past. The same goes for poorly personalized emails limited to using the subscriber’s name. Group recipients based on demographics, browsing and buying habits, location, and engagement level. These insights help you deliver relevant resources, offers, and recommendations that make each subscriber feel unique.
  • Automate key interactions: Relevance in email marketing depends on content and timing. With email automation, you can deliver meaningful messages after key interactions or on specific dates, without manual work. You can set up reminders, lead nurturing emails, and milestone campaigns on autopilot and reach recipients when they’re most likely to engage.
  • Provide value at every stage: Customers expect value before being sold anything. Depending on where they are in their journey, this may take different forms. For example, new customers need to learn how your product or service works and benefits them. On the other hand, recent buyers appreciate reassurance that their order was successful and personalized suggestions going forward.
  • Schedule your emails: The same email may perform better when sent at a time that matches subscribers’ routines. Beyond behavior, optimal timing can depend on other factors like their age and location. To identify the best time to send your emails, track email engagement, run A/B tests, and collect audience feedback regularly. 
  • Maintain your sender reputation: You should constantly monitor engagement metrics like clicks, bounces, spam complaints, and unsubscribes. Also, ensure your domain isn’t on any blocklist. This helps you address potential issues early and protect your sender reputation before things escalate. Also, if you haven’t won dormant subscribers back through your re-engagement emails, consider removing those contacts, as they may harm list quality and deliverability.
  • Respect unsubscribes: Nobody likes a list that shrinks rather than growing. But honoring unsubscribe requests shows you’re willing to give subscribers what they need, even if that means opting out. You can include a preference center in your emails to offer alternatives, or add a short poll to your unsubscribe page asking recipients why they’re leaving. Both options provide insights to improve targeting. 
  • Track performance and optimize: To evaluate campaign performance, monitor key metrics like opens, clicks, conversions, and deliverability rates. Experiment with different tactics and content formats to see what resonates best with customers and prospects. These analytics, along with audience feedback, will show you what brings results and what isn’t so you can make adjustments.

Take your emails from inspiration to execution

The most effective email marketing examples start with a good idea. But even great and innovative ideas might fall flat if they don’t align with the customer’s journey and preferences.

So, you should back up your campaigns with real-time data. Keep a close eye on evolving trends, track email analytics, and listen to customer needs so you can customize your approach.

An email marketing platform like Constant Contact simplifies this process with pre-made email templates, personalization features, plus automation and reporting tools that help you refine targeting. 

You can also create a survey page and share it through email, social media, or blog posts. That way, you’ll gather feedback directly from your audience and let it inspire meaningful tweaks in your emails. Sign up for a free trial and start building your next campaign.

FAQs

Below you’ll find answers to frequently asked questions about email marketing.

1. How can you get started with email marketing?

The first step is to find an email service for building, scheduling, and evaluating campaigns. Tools like Constant Contact or Moosend allow you to grow and manage your email list, design and automate campaigns, and monitor results to see what’s working. You can also connect your email solution with other apps in your stack without switching between tools or risking losing valuable data.

2. Which metrics should you track?

To monitor your email success, you should keep an eye on opens, clicks, conversion rates, unsubscribes, as well as email ROI and deliverability. But no email metric will tell you everything on its own. In-depth reports and repetitive patterns can give you a holistic view of your email campaign performance and point you to the elements and tactics you need to refine.

3. How do you prevent your emails from going to spam?

There are various factors that may affect your sender reputation and push your emails into spam. To ensure they land where they should, set up a double opt-in signup process. Also, authenticate your domain using SPF, DKIM, and DMARC. You’ll also need an email platform with excellent deliverability that complies with email standards. Lastly, content relevance plays an integral part in keeping subscribers engaged and your emails in their inboxes.
