9 Best SMS Marketing Platforms in 2026

Your customers probably don’t go far without their phones. That’s exactly what makes texting such a useful way to reach them. When you have a flash sale to announce, an appointment to confirm, or a last-minute event reminder to send, there’s a good chance your message will be seen quickly. In fact, 82% of consumers check a new text message within five minutes of receiving it.

The trickier part is choosing the right SMS marketing platform. There are plenty of options, and a longer feature list doesn’t necessarily mean a better choice for your business. An ecommerce store sending abandoned cart reminders has very different needs from a local salon confirming appointments or a nonprofit keeping supporters up to date.

That’s why we tested some of the best SMS marketing platforms, looking at what it’s actually like to create and send a campaign, set up automations, manage contacts, and track results. We also compared pricing and overall value to see where each platform makes the most sense.

What to consider when choosing an SMS platform?

As you compare your options, pay close attention to these factors:

• Opt-in compliance and 10-digit long code (DLC) registration: SMS is regulated more heavily than email. Look for a platform that helps you collect consent, manage opt-outs automatically, and guides you through 10DLC registration if you send messages in the US.
• Automation capabilities: Automated SMS saves time and helps you reach customers at the right moment. Look for workflows that support common SMS marketing campaigns, such as appointment reminders, order updates, and re-engagement sequences.
• Audience segmentation: The more relevant your messages are, the better they’ll perform. You should be able to segment contacts by purchase history, engagement, location, tags, or other customer data.
• Integrations: Your SMS platform should fit into your existing workflow. Integrations with your ecommerce platform, CRM, booking software, or email marketing tool make it easier to keep customer data in sync and automate campaigns.
• Pricing structure: Compare more than the starting price. Check how messages are billed, whether credits expire, if carrier or registration fees apply, and how costs change as your contact list grows.
• Two-way messaging: If customers are likely to reply with questions, confirmations, or support requests, make sure the platform supports two-way conversations instead of one-way broadcasts.
• Reporting and analytics: Look for reporting that goes beyond delivery rates. Metrics like click-through rates, conversions, revenue attribution, unsubscribe rates, and campaign performance help you understand what’s working and improve future campaigns.

Best SMS marketing platforms: overview

Here’s a quick overview of the top SMS marketing software compared.

1. EZ Texting

Best for: Sending bulk texts, alerts, and promotions to large contact lists

EZ Texting is a straightforward SMS marketing solution built to make mass texting and MMS messaging effortless. You can upload unlimited contacts, organize them into groups, and send or schedule SMS and MMS campaigns to thousands of recipients at once. For higher-volume senders, dedicated short codes can help deliver large volumes of messages more quickly.

That makes it useful for more than promotional blasts. A retailer, for instance, could announce a flash sale, while a restaurant could send a last-minute offer. You can also create automated workflows for use cases such as appointment reminders, welcome messages, abandoned carts, and after-hours replies.

One area where EZ Texting particularly stands out is list growth. Customers can opt in via SMS keywords, QR codes, embedded forms, or click-to-text links, and you can automatically organize subscribers by the keyword they use. Two-way texting then lets your team manage customer replies from a shared inbox rather than treating SMS purely as a broadcast channel.

I also found AI-assisted message creation, segmentation, reporting, RCS, and an API, plus integrations with tools such as Constant Contact, HubSpot, Mailchimp, and Zapier. The latter will allow you to keep your strategy focused on SMS while another platform handles your email marketing.

However, if you want email and SMS campaigns managed natively from the same platform, you’ll need to consider another tool. Its credit-based pricing also requires some attention because MMS messages consume three credits per recipient compared with one for a standard SMS.

Key features

• Bulk SMS and MMS campaigns
• Two-way texting and team inbox
• Automated SMS workflows
• Keywords, QR codes, and signup forms
• Dedicated short codes, 10DLC, and toll-free numbers

Pros

• Purpose-built for straightforward, high-volume texting
• Great selection of SMS list-building tools

Cons

• No native email marketing functionality
• MMS uses three times as many credits as SMS

Pricing

EZ Texting uses a credit-based pricing model, where one SMS sent to one contact typically costs one credit and an MMS costs three. Paid plans start at $25/month (billed monthly) for 500 text messages and one local textable number.

2. Attentive

Best for: Enterprises looking for deep personalization and behavioral triggers

Attentive is built for ecommerce businesses that treat SMS as a major revenue channel rather than an occasional marketing tactic. As such, you get advanced personalization, AI-powered messaging, and sophisticated customer journeys designed to maximize your conversions.

What’s interesting about the platform is how much customer data you can use to personalize campaigns. You can trigger messages based on browsing behavior, purchase history, cart activity, and predicted intent, making it particularly effective for ecommerce brands with large subscriber lists. The platform also supports MMS, RCS, two-way conversations, A/B testing, and AI tools that help optimize send times, audience selection, and campaign copy.

Despite that, smaller businesses or first-time SMS marketers may find Attentive’s feature set overwhelming, especially if they only want to send occasional promotions or reminders. It also requires more planning to get the most value from its automation capabilities, making it better suited to dedicated marketing teams than solo business owners.

Attentive recently expanded beyond SMS to include email marketing, allowing businesses to build coordinated cross-channel journeys. However, its strongest capabilities remain geared toward high-volume ecommerce brands that want to personalize every stage of the customer lifecycle.

Key features

• Advanced onsite capture tools (pop-ups, sign-up forms)
• Strong behavioral triggers tied to browsing
• AI send time optimization
• A/B testing
• Integrations with tools like Shopify, Snowflake, Salesforce, and Zendesk.

Pros

• AI-powered personalization and advanced customer journeys
• Strong compliance support

Cons

• Better suited to larger teams than small businesses
• No transparent pricing

Pricing

Unlike most SMS marketing platforms, Attentive doesn’t have publicly available pricing. Instead, you’ll need to request a custom quote based on factors such as your subscriber list size, monthly message volume, the channels you use (SMS, email, RCS, or push notifications), and any premium AI features you add. The platform also offers a free trial for eligible businesses.

3. Constant Contact

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

If you already use email marketing or plan to, Constant Contact lets you manage both channels from a single platform. Rather than treating SMS as a standalone tool, it makes it easy to coordinate text messages with your email campaigns and customer journeys.

Creating text messages is very easy. You can build campaigns from the same dashboard you use for email, segment contacts, personalize messages, and trigger automated texts based on subscriber activity. This makes it easy to send timely reminders, limited-time offers, event updates, or follow-up messages.

Beyond messaging, Constant Contact includes tools such as landing pages, sign-up forms, event management, surveys, social media scheduling, and AI-powered content creation. What’s more, you get a visual automation builder that lets you create and customize journeys that engage your audience at important touchpoints.

If you already use email to reach your customers or supporters, adding SMS can be an easy next step. You might announce a weekend sale by email, then send a quick text before it ends.

That said, businesses looking for highly advanced SMS workflows or extensive ecommerce automation may find the platform less flexible than tools like Klaviyo or Attentive. Also, SMS is available as a paid add-on rather than included with every email marketing plan, so you’ll need to factor it into your budget if text messaging will become a core marketing channel.

Key features

• Easy-to-use editor with built-in link shortener and live previews
• Customizable automation paths that include multiple channels
• Pre-made SMS templates and guided setups
• List growth tools, detailed analytics, and 300+ integrations with other apps
• AI content generator for email, text messages, social posts, and landing pages

Pros

• Beginner-friendly interface with strong contact management, templates, and automation features that make SMS accessible for small businesses.
• Combines email, SMS, social media, and events in one interface

Cons

• SMS is only available as a paid add-on
• Advanced SMS automation is limited compared to ecommerce-focused platforms

Pricing

Constant Contact offers SMS marketing as a paid add-on to its email marketing plans. Pricing starts at $10/month and includes up to 500 SMS messages. Businesses on the Premium email plan receive the first 500 messages at no additional cost.

For email, pricing starts at $12/month and includes automation, social media tools, and live support.

4. Klaviyo

Best for: Direct-to-consumer (DTC) brands and Shopify stores

Klaviyo makes the most sense for ecommerce businesses (especially those on Shopify) that want SMS to react to what customers are actually doing in their stores. Its biggest strength is the customer data behind each message. You can target shoppers using purchase history, browsing activity, engagement, location, predicted churn risk, and other profile data.

You’ll see that extra depth in Klaviyo’s automations. Klaviyo’s flows can trigger texts around events such as abandoned carts, purchases, or re-engagement and use branching logic to change what happens next based on customer behavior.

Both email and SMS use the same customer data, segmentation, and automation system, so you can build journeys that switch between email and text depending on the customer and situation.

Two-way conversations, AI-assisted optimization, list growth tools, and multi-channel attribution are also valuable tools for brands that want SMS to become a significant part of their retention strategy.

There’s a drawback here, though. Klaviyo takes longer to learn and works best if you have the marketing know-how to use its more advanced features. If you only want to send the occasional promotion, reminder, or announcement, it may be more than you need. Costs can also add up as your contact list and messaging volume grow, so it’s worth considering how much of its ecommerce toolkit you’ll actually use.

Key features

• Advanced Shopify and ecommerce triggers
• Unified customer profiles combining browsing, purchase, and engagement data
• SMS, MMS, RCS, and other mobile messaging channels
• Omnichannel reporting and revenue attribution
• Built-in consent, opt-out, and compliance management

Pros

• Effective segmentation using real-time ecommerce data
• Powerful email and SMS automation in one platform

Cons

• You’ll need to purchase a paid Email plan if you go over 250 profiles 
• Steeper learning curve for basic SMS needs

Pricing

Klaviyo calculates email and mobile messaging separately. Your base email plan depends on your number of active profiles and email volume, while your Mobile Messages plan depends on how many texts you expect to send. Prices start from $20/month (Email plan) and $15/month for 1,000 SMS messages (Mobile Messages plan).

If you want to experiment with SMS before committing to a paid subscription, there’s a free plan for up to 250 active profiles, including 500 monthly email sends and $5 of mobile messaging each month.

5. Mailchimp

Best for: Businesses that want SMS within a broader marketing platform

If you need to do a little bit of everything, Mailchimp brings email campaigns, SMS, landing pages, and automated customer journeys into one platform.

During testing, I found that the platform comes with pre-built SMS templates that empower team creativity and save time. Your SMS campaigns rely on the same audience data and automation tools as email, so you can use text messages where they make sense rather than building a separate strategy.

For instance, an online store could send an email about a sale and follow up with an SMS as the deadline approaches, while an abandoned shopper could receive a text automatically as part of a larger customer journey. Shopify merchants can even generate unique, single-use discount codes inside automated SMS messages, giving customers a more personalized incentive to come back and buy.

Mailchimp also gives you several ways to grow and engage your SMS audience. Text-to-join lets customers subscribe by sending a keyword, while two-way messaging means replies can be handled through Mailchimp Inbox. Built-in quiet-hour controls are another practical touch, automatically holding marketing texts until they’re appropriate to send.

The main limitation I found with Mailchimp is the pricing. SMS marketing is offered as a paid add-on to the Email Marketing plans. This means you may have to pay more than you would with a dedicated SMS marketing tool. Nevertheless, for businesses familiar with Mailchimp’s interface or brands that want strong email and SMS functionality, Mailchimp is a good option.

Key features

• User-friendly interface that’s easy to navigate
• Pre-built SMS templates
• A/B testing for email and SMS
• Text-to-join keywords and SMS signup forms
• Unique Shopify discount codes

Pros

• Beginner-friendly platform that makes it easy to create powerful automated journeys
• Supports SMS in the U.S., Canada, Australia, and over half of Europe

Cons

• Less advanced for SMS-first marketing strategies
• SMS requires a separate plan (credits) on top of the Email one

Pricing

Mailchimp’s SMS Marketing is a paid add-on, starting at $20/month, available on top of an eligible paid marketing plan. The add-on provides a monthly allowance of SMS credits, which are used when you send texts and, where supported, MMS messages.

So, for the Essentials plan plus SMS, the total price starts at $33/month. Note that you won’t be charged for SMS until you’re approved.

6. ActiveCampaign

Best for: SMBs comfortable with detailed automations and multi-step flows

Automation is where ActiveCampaign really earns its place on this list. Rather than using texts mainly for one-off campaigns, you can add them directly to automated multi-step workflows, triggering messages as contacts move through different paths based on their actions and data.

What impressed me most while exploring the platform was how naturally SMS fits into the automation builder. You can combine texts with email and other automation actions, add personalization, and use contact data to determine what happens next. This is useful when timing matters. For example, a training company could automatically text someone shortly before their course begins, while a subscription business could use SMS to reach customers approaching a renewal date.

ActiveCampaign has also moved further into two-way SMS. Its centralized SMS Inbox keeps customer replies and conversation history together, while the contact panel gives your team access to information such as tags, lists, and active automations without leaving the conversation. AI can even suggest replies using your Brand Kit, FAQs, website content, and previous messages.

There are plenty of tools for regular campaigns, too. The SMS editor supports personalization, shortened links, images, and scheduled sends, while opt-in forms and contact imports help you build your SMS audience. You can also bring email, SMS, and WhatsApp into the same automation, so you’re not managing each channel separately or building the same customer journey more than once.

There are some restrictions to consider. Broadcast SMS campaigns are currently limited to recipients in the U.S., U.K., and Australia, although automated SMS supports additional countries. Two-way messaging also requires a dedicated registered number in one of those three markets. This could make the platform less practical for an international audience.

Key features

• Extremely flexible journey builder with granular triggers and branching logic
• Integrated CRM and deal pipelines for sales/marketing alignment
• Two-way SMS Inbox
• AI-generated SMS content and reply suggestions
• SMS, email, and WhatsApp 

Pros

• Advanced  automation capabilities for behavior-driven SMS
• Strong two-way messaging with AI-assisted replies

Cons

• Broadcast SMS is limited to the U.S., U.K., and Australia
• May feel overwhelming for first-time users

Pricing

To get SMS in ActiveCampaign, you’ll need at least the Plus plan ($59/month billed monthly) and then the SMS add-on with a recurring monthly credit allowance. Prices start at $21/month with 1,000 credits included.

7. Omnisend

Best for: Ecommerce brands looking for a more affordable Klaviyo alternative

If you like Klaviyo’s ecommerce-first approach but not necessarily its price tag, Omnisend is worth a closer look. It offers many of the capabilities online stores actually need, including behavioral automation, segmentation, and coordinated email and SMS campaigns, while generally costing less across common contact tiers.

The visual automation builder lets you add email, SMS, and web push notifications to the same workflow, then use delays, conditional splits, and shopping behavior to determine what each customer receives next. That makes Omnisend a good middle ground for stores that want ecommerce automation without immediately jumping to a more complex platform like Klaviyo.

Other standout features that caught my attention were the Gamified opt-in forms and the preference center. The latter lets customers choose what content they want to see and how often. Omnisend also tracks clicks, conversions, purchases, and attributed revenue, which makes it easier to see whether SMS is actually contributing to sales.

Like Klaviyo, this email and SMS marketing platform is better suited to ecommerce businesses. As such, SaaS companies or businesses looking primarily for bulk texting may find much of its toolkit unnecessary. MMS is also limited to U.S. and Canadian recipients.

Key features

• Plug-and-play ecommerce automations
• Behavioral segmentation and real-time triggers
• Unique SMS discount codes
• Global SMS sending
• AI-powered personalization

Pros

• Strong omnichannel automation built specifically for ecommerce
• SMS available internationally, with volume discounts

Cons

• Less compelling outside ecommerce
• MMS only available in the U.S. and Canada

Pricing

SMS marketing is available with Omnisend’s Pro plan, which starts at $59/month. You can purchase Global SMS credits that start at $10/month for 1,111 SMS messages.

8. SimpleTexting

Best for: Two-way customer conversations

Reviewing SimpleTexting, I found it much easier to get around than some of the broader marketing platforms on this list, largely because texting isn’t buried among dozens of other tools. You can send a campaign, manage contacts, set up automations, and respond to customers without much hunting around.

The Inbox was one of the most useful parts of the platform. Incoming texts appear as individual conversations, and you can assign them to teammates, leave internal notes, snooze conversations, and see the contact’s details alongside the thread. For a service business, that could mean sending a schedule change to everyone affected and then handling individual questions from the same dashboard.

SimpleTexting is equally capable of broadcasting as it is of chatting. It supports mass SMS and MMS, scheduled messages, autoresponders, audience segments, polls, and data collection. Keywords and web forms also give you straightforward ways to grow your subscriber list.

What you’re not getting is a full email marketing platform. SimpleTexting integrates with tools such as Mailchimp, HubSpot, and Zapier, but if you want native email-and-SMS journeys, you’ll find other platforms on this list better suited.

Key features

• Mass SMS/MMS
• Two-way inbox
• Autoresponders
• Polls
• Team collaboration

Pros

• Good for managing customer conversations
• Unlimited contacts and incoming messages

Cons

• Not the best tool for sending individual messages
• No built-in email marketing features

Pricing

Plans start at $29/month for 500 messaging credits, with lower per-message costs at higher volumes. Incoming SMS messages are free, and unused credits roll over for one month. A 14-day free trial is available without providing a credit card.

9. HubSpot

Best for: CRM-driven SMS automation

HubSpot brings SMS into its broader customer relationship management (CRM) and automation tools. Rather than focusing on one-off texts, it lets you use SMS as part of customer journeys alongside your other channels.

You can send or schedule SMS campaigns, personalize messages with CRM data, segment recipients, and bring SMS into HubSpot’s automation workflows. For example, a business could text a lead with a meeting reminder, send an event update to registered attendees, or follow up with a time-sensitive offer based on where someone is in the customer journey.

HubSpot also supports two-way SMS, with replies flowing into its conversations inbox so teams can continue the interaction from the same platform. Of course, email and SMS can be combined in the same workflow.

Compared with Mailchimp and Constant Contact, HubSpot goes further into CRM data, lead management, and complex automation, making it more appealing to growing businesses with longer or more involved sales cycles. The downside is that you’ll pay considerably more to access that depth.

Another important limitation is geographic availability. HubSpot currently sends marketing SMS from US-based numbers and can only message +1 numbers in the US and Canada, so it’s not the right choice for businesses with an international SMS audience.

Key features

• CRM-powered SMS personalization and segmentation
• Highly customizable SMS and email workflows
• Scheduled and one-off SMS campaigns
• SMS consent and opt-out management
• Campaign reporting and attribution

Pros

• CRM data and automation for highly targeted SMS
• Combines SMS, email, sales, and customer data in one ecosystem

Cons

• Significantly more expensive than most SMS marketing tools
• SMS sending is currently limited to U.S. and Canadian numbers

Pricing

HubSpot doesn’t offer SMS as a standalone service. You need a Marketing Hub Professional or Enterprise plan (starting at $890/month), plus the Marketing SMS Long Code Add-On ($75/month). The add-on includes 1,000 message segments per month.

Check country coverage and SMS requirements

Before choosing an SMS platform, confirm it supports your business’s location and can reach your subscribers. Constant Contact’s built-in SMS is available to eligible businesses in the U.S. and Australia. ActiveCampaign limits broadcast texts to the U.S., U.K., and Australia, while HubSpot’s long-code SMS reaches U.S. and Canadian numbers.

For U.S. campaigns, look for tools that record written permission for marketing texts, handle opt-outs, and help with the registration required for your sending number. If you’ll reach subscribers elsewhere, check these requirements:

• Canada: Canada’s Anti-Spam Legislation (CASL) requires consent, clear sender and contact details, and an easy unsubscribe option for commercial texts. You must also process opt-outs promptly, no later than 10 business days after receiving them.
• U.K. and EU: Marketing texts to individuals generally need consent that specifically covers SMS. Under the UK’s PECR rules, a limited “soft opt-in” can let you promote your own similar products or services without a separate sign-up. You must collect the number directly during a purchase or sales discussion and offer — and honor — an opt-out at collection and in every text. Check each EU country’s national rules.
• Australia: The Spam Act 2003 requires consent, your business name and contact details, and an easy unsubscribe option. If your business name appears at the top of your texts as the sender, register that name through your messaging provider. Since July 1, 2026, unregistered sender names appear as “Unverified.” This registration rule doesn’t apply to texts sent from a regular phone number.
• New Zealand: The Unsolicited Electronic Messages Act 2007 requires consent, sender and contact details, and a free unsubscribe option for commercial texts. You must also honor opt-out requests within five working days.

Before committing, test how the platform stores consent and handles unsubscribes. Then, confirm that opting out stops both scheduled campaigns and automated promotional texts.

Choosing the best SMS marketing software for your business

The best SMS marketing software should balance automation, integrations, and compliance with ease of use. Choose a platform that’s more than you need, and you could end up paying for advanced features you rarely touch. Go too simple, and you may quickly run into limitations as your SMS strategy grows.

Start with what you actually want SMS to accomplish. That might mean sending promotions to a large audience, having one-on-one conversations with customers, automating ecommerce messages, or adding timely texts to your existing email campaigns. From there, compare the platforms that support those use cases at a price that makes sense for your sending volume.

And remember, you don’t need the most advanced SMS platform to get results. You need one that makes it easy to send relevant messages at the right time and gives you room to grow when you’re ready. If you want to combine SMS with the email campaigns you’re already sending, Constant Contact brings both channels together in one platform, along with automation, segmentation, and reporting. Start your free trial and see how SMS can fit into your broader customer communication strategy.

FAQs

Here are some frequently asked questions about SMS marketing.

1. Is SMS marketing still effective?

Yes, consumers are more receptive to business texts than ever. According to EZ Texting’s 2026 Consumer Texting Behavior Report, 67% of consumers say they’re more likely to purchase from a business whose texts they subscribe to. When paired with email, SMS gives you a direct line to customers who’ve already said yes to hearing from you.

2. Is SMS marketing legal in the U.S.?

Yes, SMS marketing is legal with consent. The Telephone Consumer Protection Act (TCPA) requires prior express written consent before you send marketing texts. You also need to honor opt-out requests promptly and register your phone number through 10DLC. A good SMS platform builds these safeguards into the workflow, so compliance becomes part of the process rather than a separate task.

3. Do I need a dedicated phone number to send marketing texts?

You need a registered number, but you have options. Most small businesses use a 10DLC long code, which is a standard 10-digit number registered for commercial messaging. Toll-free numbers and short codes (such as five- or six-digit numbers) are also available, though short codes are typically used by larger brands with high message volumes.

4. Can I keep my current business phone number?

Usually, yes. Many SMS platforms can enable text messaging on your existing business phone number after you complete 10DLC registration. This lets you send marketing texts from a number your customers already recognize.

5. How much does SMS marketing cost?

Pricing varies by platform, but most use tiered or contact-based models with per-message or credit components. Look for transparent pricing that fits your volume. Affordable options exist for small businesses, and many platforms offer free trials so you can test before committing.
