SMS marketing platforms: How to choose the best one for your business

Nearly 90% of today’s consumers would prefer to read a text rather than open an email or answer their phone. Marketers across industries are taking note, and expanding their strategies to reach customers over text.
SMS marketing offers countless benefits — it’s cost effective, has high open rates, and offers strong engagement rates. But there are also countless platforms on the market. With so many options available with different features, pricing models, and integrations, it’s challenging to know which one is best for your business’s specific needs.
Additionally, with SMS security and compliance becoming more top-of-mind for businesses, it’s essential to choose SMS marketing software that will help you text compliantly and build trust with your customers. But knowing what compliance features to look for adds another layer of complexity.
We created this guide to give you all the resources you need to choose the best SMS marketing platform for your business. We’ll cover:
- The different types of SMS marketing software available
- Reviews of the best types of software
- What essential features to look for in a text marketing platform
- Compliance features to consider
Before we start, you might be wondering how Heymarket fits into this. We’re an SMS marketing platform that covers a wide range of needs and we’ll explain how below. But with so many types of businesses and marketing software out there, there’s a chance a different kind of platform might be a better fit. We’ll explore all of that and more.
What is an SMS marketing platform?
An SMS marketing platform (also called a text marketing platform, SMS marketing software, or SMS marketing solution) empowers businesses to connect with their leads and customers at scale, primarily by sending one-to-many texts.
Traditionally, SMS marketing platforms just allowed for sending SMS, but nowadays SMS marketing software supports a variety of channels, including SMS, MMS, Facebook Messenger, Apple Messages for Business, WhatsApp, and more. Some SMS marketing platforms also incorporate email and app-based push notifications for a comprehensive approach to mobile marketing.
SMS marketing benefits
Businesses across industries use SMS marketing because it offers a scalable and cost-effective way to reach customers on their preferred channels. Eighty-five percent of smartphone users prefer messages to emails or calls, and text messages have a 98% open rate (email, on the other hand, has an average 20% open rate).
But beyond just reaching more people, texting allows marketers to engage and nurture their audience into loyal customers. Consumers are 4.5x more likely to respond to an SMS marketing message than an email. And people who get a marketing text are 40% more likely to convert than those who don’t.
Types of text marketing platforms
While nearly every type of business can benefit from SMS marketing, there are a variety of platforms serving different business sizes and needs. Here’s a breakdown of the most common types of SMS marketing software:
Outbound focused: For businesses that mainly want to send texts to lists
Outbound-focused texting platforms are geared toward helping businesses reach large numbers of people at once. They primarily allow for sending 1-way text messages to lists of contacts, also known as a text blast or mass text message. They may have some 2-way texting features, but most of their functionality focuses on outbound texting.
Pros of outbound-focused platforms:
- Easy to set up: Because these platforms focus on sending texts to lists, they’re usually easy to start using.
- Large list sizes: These platforms typically allow you to send texts to large groups of people with minimal restrictions. (When this is the case, be mindful that you’re texting compliantly by only messaging those who have agreed to receive your texts – more on this below.)
Cons of outbound-focused platforms:
- Limited functionality: Even outbound-focused platforms tend to offer basic 2-way texting, but this can restrict how much your contacts can respond to your texts or ask questions about your products and services.
- Marketing-only: If you need to use texting outside of your marketing team, outbound-focused platforms offer few features that your customer service, sales, and other teams can get value from.
- SMS-only: Many of these platforms just support SMS (some also support MMS). But with 90% of internet users trying other chat apps, supporting other messaging channels is becoming increasingly essential for businesses.
- Compliance considerations: As mentioned above, these platforms allow you to send texts to large list sizes, but that may come at the cost of compliance features that help ensure you’re only texting opted in customers.
Conversational, omnichannel messaging: For personalized 1-way and 2-way texting across the full lifecycle
Conversational messaging platforms offer the ease of use of outbound-focused tools, but support both large-scale outreach and ongoing two-way conversations. Many now go beyond texting alone, combining SMS with email and other messaging channels so teams can manage outreach, replies, and follow-ups in one place. They also include personalization and compliance features that help businesses build stronger, more consistent customer relationships.
Pros of omnichannel messaging platforms:
- Intuitive: These platforms are quick to set up to start having conversations in minutes.
- Multi-directional: Conversational marketing platforms allow for both outbound and inbound texting, so customers can respond to any text and have a 1-on-1 conversation.
- Business-wide uses: Because they’re multi-directional, conversational marketing platforms are useful across the customer lifecycle. They offer features to use across your business, from customer service to sales and internal operations.
- Robust: In addition to mass texting, conversational marketing platforms offer advanced marketing features. You can segment contacts into targeted lists, schedule texts, create automations, send text templates, and use custom fields that automatically personalize your texts.
- Omnichannel: Conversational marketing platforms offer SMS and MMS, plus popular messaging channels like Facebook, Instagram, Google Business Messages, Apple Messages for Business, and WhatsApp.
- Opt-in management and security: These platforms help you track customers’ opt-in and integrate texting with your CRM and other business apps, giving you full control of your data.
Cons of omnichannel messaging platforms:
- Cost: Conversational messaging platforms can sometimes be more expensive than outbound-only platforms, but they also allow you to use one centralized texting platform for all of your customer messaging. Plus, sending personalized and targeted texting campaigns has an ROI of 4x.
Build-you-own texting platforms: For enterprises that want to create custom solutions
Build-your-own texting platforms are geared toward businesses invested in customizing their own SMS marketing solution. They offer near endless features, and often require businesses to develop their own applications. Some offer low- and no-code solutions requiring basic technical knowledge.
Pros of build-your-own texting platforms:
- Flexible: These platforms can perform a wide variety of functions as long as your business invests the time and resources to set them up.
- Powerful: These platforms allow brands to build robust messaging experiences, from automated campaigns to workflows for your call center.
- Omnichannel: These platforms allow you to connect with a wide variety of other messaging channels.
- APIs and integrations: These platforms include robust APIs and integrations, so you can connect SMS to your website and other tools.
Cons of build-your-own texting platforms:
- Resource intensive: These solutions base their costs on the number of messages you send, so they can be costly for businesses sending higher message volumes. They also require internal time and resources, including development costs for setup and maintenance.
- Technical setup: Build-your-own solutions are technical, so your team will need a developer or someone who’s familiar with coding to implement them.
- Complex interface: Once you’re set up, it takes time and training to get your team up and running on the platform.
- Intensive to maintain: Because these solutions are so programmable, they can also be more difficult to maintain.

The best conversational SMS marketing software: Heymarket
Heymarket is a conversational messaging platform that helps businesses manage both outbound outreach and one-to-one conversations across channels. In addition to SMS and MMS, Heymarket now supports email in its omnichannel shared inbox and brings together web chat and popular messaging apps in one place. That gives teams a shared view of customer conversations and helps them respond faster without switching between tools.
Strengths 💪 Heymarket is a strong fit for teams that want to use messaging across the full customer lifecycle, from lead capture and marketing outreach to customer service and follow-up conversations. It combines list growth, segmentation, campaigns, templates, personalization, and two-way messaging in a shared workspace built for teams.
Heymarket’s standout strength is that it pairs outbound messaging tools with collaboration features like shared inboxes, assignments, and private comments. Businesses can use custom fields, CRM integrations, and automations to send more relevant messages and keep conversations organized across teams. With newer omnichannel capabilities, Heymarket also supports email alongside texting in a unified workflow.
Drawbacks 🚩 Heymarket is designed for businesses that want more than simple one-way promotional texting. If your team only needs basic mass text sends and does not need shared inboxes, two-way conversations, automations, or cross-channel messaging, it may offer more functionality than you need.
- Heymarket offers annual and monthly plans starting at $19/month
- Businesses then purchase messaging bundles for $30/1000 messages
- Heymarket offers a 14-day free trial
- SMS, MMS, email, web chat, omnichannel messaging (Apple Messages for Business, Facebook and Instagram Messenger, WhatsApp)
- List building
- List sends
- Scheduled messages
- Drip campaigns
- Automations (including CRM automations)
- Customer profiles
- Segmentation
- Compliance tools including opt-in management
- Compliance certifications including HIPAA and SOC 2 Type 2
- Security tools including SAML SSO, 2FA
- Advanced 2-way SMS with a shared inbox, message routing, assignments, and private comments
- Personalization with reusable templates and custom fields
- Reporting
- Robust integrations including Salesforce, HubSpot, Microsoft Teams, Shopify, Slack, and more
Heymarket is a strong option for teams that want to combine campaigns, two-way conversations, and team collaboration in one place. It is especially useful for businesses that want to manage texting and email together through a shared inbox, while also using lists, automations, and personalization to scale customer communication.
The best outbound-focused SMS marketing software: Attentive
Attentive is an SMS marketing platform that focuses on eCommerce brands. While it also supports email, Attentive emphasizes that it’s an SMS-first platform.
Strengths 💪 Attentive provides all of the crucial features marketers need for sending outbound SMS at scale. It offers customizable opt-in tools that help with compliance, which is especially helpful if you’re focused on sending texts to large list sizes. You can also build customer profiles based on their actions and segment them based on behaviors to create campaigns.
Attentive’s biggest strength is in its customizable reports, which allow you to analyze revenue data from your messaging campaigns. While Attentive focuses on outbound marketing, it also allows recipients to text keywords or numbers to trigger an auto-reply.
Drawbacks 🚩 With Attentive’s focus on outbound texting, it has limited options for answering customers’ questions or having two-way conversations with them. To forward messages to your customer service team, you would need to integrate Attentive with your customer service platform. Attentive has the integration to allow this, but it complicates the experience for your team and potentially your customers.
- Attentive does not list its pricing on its website, but other sites have estimated it to be around $300/month
- Attentive offers a 30-day free trial to test its features
- SMS, MMS, and email
- List building
- List sends
- Scheduled messages
- Campaigns
- Customer profiles
- Segmentation
- Compliance tools
- Keyword auto-replies
- Personalization
- Reporting
- 100+ integrations with primarily eCommerce and martech tools
Attentive is a good option for large businesses that want to send scaled outbound campaigns, but is not an all-in-one solution for brands that want to have 2-way conversations with customers directly within the platform.
The best build-your-own SMS marketing software: Twilio
Twilio is a comprehensive solution for SMS marketing. With the right resources in place, businesses can use it to support nearly any marketing strategy. While many of Twilio’s tools are built for developers, it offers plenty of no-code features that just require basic technical skills to set up.
Strengths 💪 Twilio is a flexible SMS marketing solution because you’re essentially building from scratch. It has powerful APIs that allow you to build SMS marketing into your website and existing apps. It also offers robust capabilities for segmenting your contacts and building automated campaigns to nurture them through their full customer journey using their Studio feature. Additionally, Twilio can be cost effective since you’re primarily paying for how many messages you send, your carrier fees, and your phone line(s).
Drawbacks 🚩 Twilio offers no-code features and an extensive code library, but its setup requires enough technical knowledge to know where to copy and paste the code. If you don’t have that skill set on your team, you may be better off looking for an out-of-the-box solution that you can get up and running within hours.
- Messages from $0.0079/text plus carrier fees of ~$0.003/text
- Phone numbers from $1.15/month
- SMS, MMS, Facebook Messenger, Google’s Business Messages, WhatsApp, and web chat
- List building
- List sends
- Scheduled messages
- Campaigns
- Segmentation
- Automations
- 2-way SMS
- Personalization
- Link shortening
- Campaign tracking
- APIs to connect with a wide variety of platforms
Twilio offers features to support SMS marketing plus texting throughout the entire customer lifecycle. It’s a fitting option for businesses with some technical resources who are willing to dedicate time to setting up, customizing, and maintaining their solution. However, it is not an out-of-the box solution and requires both time and basic coding familiarity to get up and running with.
How to choose the best SMS marketing platform for your business’s needs
With a wide variety of platforms on the market, it can be overwhelming to choose the right one for your business’s specific SMS marketing needs. Here are the most important questions to ask and factors to consider:
1. Do I just need to send texts for marketing, or throughout the customer journey?
Your answer to this question will determine if you can go with an outbound-focused solution (like Attentive) or a conversational marketing solution that allows you to connect texting to the rest of your customer lifecycle (like Heymarket).
2. What channels are my leads and customers on?
Send out a survey or poll your customers to understand which communications channels they prefer to use. If it’s primarily SMS, you can choose an SMS-first solution. If email is also important, look for a conversational or omnichannel messaging platform that supports both texting and email in one place.
If they want to reach you on a variety of channels—like SMS, email, web chat, Facebook or Instagram Messenger, Apple Messages for Business, or WhatsApp—an omnichannel solution will better support your needs.
3. What are your crucial CRMs and apps?
Most SMS marketing platforms offer integrations and APIs to connect texting to the business apps you use every day. But not all integrations offer the same capabilities and depth of features. Evaluate how important it is for your team to send texts from your main platforms. If, for example, you need to be able to build SMS campaigns and send text blasts from HubSpot, you should choose the platform with a HubSpot integration like Heymarket that allows you to add texts to HubSpot Workflows and send list messages directly from your CRM.
4. How important is security and compliance?
Most SMS marketing platforms have some compliance features, but if security and compliance are a priority for your business, you should look for platforms that:
- Allow customers to automatically opt in and out based on simple keywords like STOP
- Allow your team to manage opt in and opt out in your texting platform: from your customer profiles, when you create a contact, when you import contacts, and at scale through APIs
- Security certifications such as SOC 2 and industry-specific standards like HIPAA
Essential features to look for in an SMS marketing platform
Basic features
Nearly every business that does SMS marketing needs these basic features. Ensure the SMS marketing platform you choose includes:
- Contact segmentation: The ability to filter customers based on their contact details or behavior into lists
- List messaging: The ability to send a mass text to a segmented list of customers
- MMS: Visual messages attract 20% more campaign opt-ins than SMS. Ensure the platform supports sending multimedia messages
- Templates: The ability to save frequently-used messages to use in campaigns, scheduled messages, and automations
- Personalization: You should be able to insert merge tokens into your text templates that populate with customer details the moment they send
- Keyword auto-replies: Customers should be able to text a keyword and automatically trigger a response
- Keyword opt-in and opt-out: Your contacts should be able to subscribe and unsubscribe to your SMS messages by texting a simple keyword like START, STOP, or QUIT
Advanced features
Depending on your business’s specific needs, you might need advanced features to support your SMS marketing strategy. Look for these ones:
- Drip campaigns: You should be able to create a series of messages that send on a specific schedule or number of days apart to engage leads
- Automations: Beyond keyword auto-replies and campaigns, some platforms allow for advanced automations. They can automatically send a text based on the time of day, customer intent, or what messaging channel they’re using. They can also streamline non-messaging tasks like adding a customer to a list or campaigns, or assigning the conversation to a team member.
- Reports: Robust texting platforms offer reports analyzing messaging performance, volume, and campaign metrics
- Advanced opt-in management: Beyond simple keyword opt-in and opt-out, advanced messaging platforms should allow your team to manage customers’ opt-in throughout the platform, including on their contact record, when you upload contacts from a CSV, and through APIs
Best practices for growing your SMS marketing ROI
Now that you know how to choose an SMS marketing platform and the core features you need, here are the key steps to keep in mind as you launch or hone your SMS marketing strategy. These best practices will help you improve engagement while minimizing unsubscribes to grow your overall ROI from SMS marketing.
1. Always get customers’ permission to text them
To stay compliant with telecom regulations like the Telephone Consumer Protection Act (TCPA), all businesses that text must get customers’ opt in before messaging them. There are a variety of ways to do this, such as texting a keyword or filling out a form on your website.
Most importantly, you need to understand opt in and opt out, only text customers who you can demonstrate have agreed to receive your messages, and make it easy for them to unsubscribe. Your business texting platform should make it easy to see your contacts’ opt-in status, and only send texts to opted-in customers.
2. Segment your lists for the most relevant texts
Once you have customers’ permission to text them, don’t go blasting texts to every contact on your list. Segmented messages drive 83% higher engagement on average. Your texting platform should allow you to segment your lists based on audience behaviors and preferences. The smaller the list and the more personalized your messages, the more likely your recipients will engage.
3. Encourage conversations
One of the most unique aspects of texting is how easy it is for customers to reply and start an immediate conversation. Embrace conversational marketing by sending content that provides genuine value, then encouraging your recipients to respond with questions. This approach focuses on the customer’s needs rather than marketing a product, allowing you to improve engagement, build better relationships, and ultimately convert more customers.
4. Personalize every message
Brands that personalize their texts see an average 4x in ROI. You can do this easily by using text templates and adding custom fields that automatically insert each customer’s details when you send the message.
5. Automate and scale
As your SMS marketing strategy grows, chances are that your engagement and list size will grow too. With more messages to send and respond to, automations can help you meet the demand by auto-piloting simple messaging tasks so your team can handle more texts in less time.
