Consider using text message (SMS) marketing to stay in touch by sending friendly updates about promotions, deals, and launches directly to their phones. What makes SMS messaging such a valuable marketing channel? Americans reportedly check their phones nearly 200 times a day on average, meaning it’s an easy way to connect instantly.

Finding the best SMS marketing platform isn’t necessarily an easy task, but it’s not for a lack of options. There are many different platforms on the market that allow you to automate and send texts at scale.

In this blog we’ll compare the best email and SMS marketing tools on the market. Read on for an in-depth comparison of the top options on the market, looking at factors like features, usability, automations, integrations, compliance, and support. We’ll also tell you how to pick the right SMS marketing tool for your team based on your business needs and goals.

What to evaluate before you choose

Small businesses who are on the lookout for a SMS marketing tool have a lot of options to consider, so it’s best to define evaluation criteria from the start. Teams should be on the lookout tools that are powerful enough to deliver on every expectation without breaking their budget.

This can look like clear opt-in compliance, simple automation triggers (like welcomes, reminders, and promos), proper segmentation, and reliable integrations. The best SMS marketing platforms will also offer predictable pricing models and accessible support.

1. Constant Contact: The best SMS marketing platform for businesses

Best for: Small businesses that want SMS and email under one roof.

Features: 

• Unified SMS plus email platform with approachable automation paths.
• Built-in SMS templates and guided setups. 
• Built-in list growth, compliance, analytics, and key integrations.

Constant Contact gives small business owners all of the core essentials in one place. We’re talking SMS, email, automations, list growth, compliance tools, and built-in analytics. Our set up is quick and beginner friendly, helping businesses scale fast without a steep learning curve.

If you’re a small business that wants to control your SMS and email marketing services under one platform, Constant Contact was designed for you.

Add in compliant list growths and automations that don’t require technical expertise to get started, and you’ve got yourself a very strong SMS marketing service for SMBs. 

Constant Contact was intentionally built with a simple setup. This allows small businesses to get up and running fast without having to sit through a steep learning curve or a complex technical setup. Teams can simply launch upon logging in.

Inside the platform, Constant Contact offers a visual builder that makes automation intuitive.

Users can drag, drop, and customize journeys without needing deep knowledge of marketing operations. Prebuilt paths give users the option to set up important touchpoints in minutes, not days or even hours.

Constant Contact also supports key customer relationship management (CRM) connections. This can include a simple Salesforce integration for syncing contacts and activity.

SMBs who use Constant Contact can also benefit from prewritten text message templates and a guided setup. This means businesses can launch compliant SMS campaigns quickly without needing prior experience or specialized marketing support.

Constant Contact also comes with an integrated list builder. This helps marketers make sure they’re compliant across geographies and that they’re giving subscribers proper opt-in options when necessary.

You can even segment contacts by engagement level to target your most active or at-risk subscribers — and Constant Contact will walk you through exactly how to do it.

Because everything in the platform — from templates to email marketing automations to built-in compliance — is built to deliver quick wins, most users can send their first campaign the same day they sign up. This is ideal for teams who want immediate impact.

2. Attentive: Advanced personalization for growing ecommerce brands

Best for: Ecommerce brands looking for deep messaging personalizations and behavioral trigger capabilities.

Features:

• Advanced onsite capture tools (pop-ups, sign-up units).
• Strong behavioral triggers tied to browsing.
• Highly personalized SMS/MMS campaigns with usage-based pricing.

Attentive, as its name would suggest, is built for the small business who wants to keep its customers in the loop. Designed with ecommerce in mind, Attentive offers strong automations, integrations, and workflows that in many cases are “plug and play.”

But, it’s important to note that pricing is typically charged on a per-use basis. Businesses should consider their use frequency when comparing prices.

Attentive is known for being one of the best SMS marketing platforms for advanced onsite capture tools. This includes things like pop-ups and sign-up units, which can be particularly useful for ecommerce demands who have to capture interest the moment it happens.

Attentive is able to trigger lead captures through behavioral triggers tied to browsing, cart activity, and purchase history. Busy online stores will feel the biggest benefit, but this feature may feel more advanced than some teams need.

The same could be said for Attentive’s personalization features, which are rather sophisticated. For a business that is looking for a more simple and straightforward email and SMS unification, Constant Contact is a good alternative and might make more sense price-wise.

3. Klaviyo: Shopify-first email & SMS for ecommerce and DTC brands

Best for: Online stores and DTC brands that want deep ecommerce triggers, data-driven segmentation, and tight Shopify alignment.

Features:

• Deep Shopify and ecommerce triggers and data-rich segmentation.
• Predictive analytics, lifecycle benchmarks, and A/B testing.
• Unified customer profiles combining browsing, purchase, and engagement data.

Stores that sell directly to consumers can benefit from Klaviyo’s deep Spotify integration and native ecommerce triggers. Think of those that ship online to their customers without using a third-party retailer or marketplace.

Klaviyo offers powerful capabilities, including data-driven segmentations that punch above their weight. This is made possible by the platform’s rich customer profiles. These combine browsing history, purchases, and engagement data to create full-scale customer profiles.

Built for growth-minded businesses, Klaviyo offers A/B testing, predictive analytics, lifecycle and milestone benchmarking. These capabilities allow businesses to optimize performance and, in turn, revenue over time.

These powerful flows and in-depth analytics can be useful and earn Klaviyo a spot on most “best SMS marketing software” lists.

But, the learning curve might be uncomfortable for some teams.  Klaviyo requires time, data volume, and marketing expertise. If teams need a tool with a faster setup and unified email and SMS, they should consider Constant Contact.

4. Mailchimp: All-in-one marketing starter

Best for: Generalists who want broad marketing tools and a familiar user interface (UI).

Features:

• Broad, beginner-friendly toolkit, with email, landing pages, basic CRM, and automations.
• Large template library for quick creative flexibility.
• Easy-to-use UI, but features and cost scale quickly as needs increase.

Mailchimp is certainly one of the most popular household names on our list, and there is a reason for that.

It’s a great tool for marketers who need to do a little bit of everything on a familiar UI. A little bit of everything includes email, landing pages, light CRM functionality, and basic automations.

Mailchimp also comes with a large library of usable templates, offering enough choices to empower team creativity.

However, as businesses add contacts or opt for more advanced features, costs can quickly add up. Teams should review add-ons and usage-based pricing before deciding whether Mailchimp is the right tool for them.

Also, while versatile, Mailchimp’s automation and SMS options may feel a bit over-complex for what SMBs are looking for. If your team’s idea of the best SMS marketing service is one where email and SMS feel unified, check out Constant Contact.

5. HubSpot: CRM-centric automation for scaling teams

Best for: Sales-led orgs that want CRM + marketing alignment and robust automation

Features:

• SMS features powered by deep CRM data and enterprise-grade automations. 
• Highly customizable multi-branch workflows across sales and marketing.
• Best for scaling teams, though key features sit behind higher-tier plans.

Like Mailchimp, HubSpot is also a popular choice and a regular feature among lists of the best SMS marketing platforms. If you want CRM fields and marketing automations to live in the same place as your SMS strategy, then HubSpot is worth checking out.

Many businesses use HubSpot for its CRM, so it seems logical to bring on HubSpot to help with SMS efforts, too. With sales, marketing, and service all in one spot, it makes it easy to send SMS messaging to the right contacts and the right time. 

But, keep in mind that many of HubSpot’s most valuable features sit behind higher-tier plans. Carefully evaluate the cost of every feature that you’ll need, because they can quickly add up.

Also, while HubSpot ’s automation engine is flexible, this can get complex very quickly. These multibranch workflows can require staff oversight, which can quickly overwhelm small teams. If you want something lightweight that has no risk of bloat, consider Constant Contact.

6. ActiveCampaign: Journey builder & deep automation

Best for: SMBs comfortable with detailed automations and multistep flows.

Features:

• Extremely flexible journey builder with granular triggers and branching logic.
• Integrated CRM and deal pipelines for sales/marketing alignment.
• Advanced automations that make it easy to orchestrate an entire SMS flow. 

ActiveCampaign is beloved among SMBs who seek out detailed automations and multistep flows. It comes jam-packed with a strong SMS journey builder that helps teams visualize the funnel through their customers’ eyes, a task that can be surprisingly hard for marketers.

Detail-oriented teams will appreciate Active Campaign’s fine-grained control over triggers, conditions, and branching logic. Teams can segment their SMS messaging based on customer engagement, actions, and lifecycle stages. 

For some teams, this might seem like a bit much. But for teams looking to tailor every step of the customer journey in a very specific way, this could be the best SMS marketing software out there.

For example, ActiveCampaign offers the ability to segment customers by engagement level, so you can adjust your messaging based on the receiver’s level of interest. (It’s worth noting that Constant Contact also has this capability.)

If you’re planning to take up ActiveCampaign, plan for some startup time, so your team can get familiar. The advanced automations can require consistent oversight, so it can be helpful to have a team member or two dedicated to knowing the ropes.

7. Omnisend: Ecommerce flows & multichannel

Best for: Ecommerce marketers who want SMS + email + push with plug-and-play flows.

Features:

• Plug-and-play ecommerce automations.
• Multichannel messaging across email, SMS, push notifications.
• Built specifically for online stores wanting fast, prebuilt workflows.

Omnisend is designed for ecommerce marketers, offering powerful workflows and triggers right out of the box. What makes it one of the best email and SMS marketing platforms is its ability to support multichannel campaigns.

It empowers marketers to send email, SMS, and push communications. This ensures customers are well-connected throughout their buying journey. And, it even offers opt-in and preference controls, so customers can choose what they want to see and how often.

Again, through the ecommerce lens, Omnisend comes with store-connected features like cart recovery, product recommendations, and browse-abandon triggers. There is no setup required, which makes it ideal for teams who have always wanted to set up these functionalities.

In this same vein, businesses outside of retail may find certain features tedious. SMBs who want broader use cases and simpler list-building tools may prefer a more versatile platform (like Constant Contact). This way, they can access certain features like signup forms and list tools.

Choosing the best SMS marketing software for your business

The best SMS marketing software for you should balance automation, integrations, and compliance with ease of use.

Choose software that’s more than what you need, and you might feel so overwhelmed by features you can’t bring yourself to even open the software. Anything less, and you’ll feel too frustrated to even start to consider return on investment.
