Every company that offers SMS marketing capabilities boasts dozens of features for brands.

But not all SMS marketing platforms are created equal, and that makes choosing the best one for your business a complicated challenge.

SMS marketing automation, or text message marketing automation, refers to the ability to create, send, and deliver SMS communications at scale. Vendors make promises ranging from sophisticated personalization and segmentation to A/B testing, artificial intelligence-led analytics, and more.

But what’s the best SMS marketing service for your specific business needs? Which one will best help you:

  • Meet your goals?
  • Appropriately track SMS attribution as part of your holistic marketing funnel?
  • Segment your audiences based on zero- and first-party data?
  • Use that data to personalize your text messages for higher, more sustainable customer engagement?

Below is our list, in no particular order, of 4 of the top SMS marketing tools for delivering the kind of customer experience today’s consumers demand. It’s not a comprehensive list, and of course we’re a little biased. But we’ve tried to select a list of SMS marketing platforms that encompasses a wide range of different business sizes and use cases.

Here, we break down why you might want to use each SMS marketing software—and why you might not.

1. Klaviyo

Why you might not want to use Klaviyo for SMS

  • You need your provider to offer a fully managed SMS program. While Klaviyo doesn’t run your SMS program for you, we do work with a wide range of SMS-certified agency partners that can. Klaviyo also offers onboarding to help you get your SMS program up and running, as well as customer success managers to help your SMS and email program see better results.
  • You’re looking for a more ad-hoc pricing model, rather than one that’s inclusive of carrier and platform fees. Klaviyo offers transparent month-to-month plans and annual contracts with no additional fees, so you can choose whatever path makes the most sense for your business.
  • You need access to SMS campaign features such as audio and video messaging. Klaviyo does not support these features at this time.
  • You need to send transactional SMS notifications in an ecommerce platform other than Shopify. Klaviyo only supports Shopify transactional SMS at this time.
  • You need advanced conversational SMS capabilities. Klaviyo does not offer live sales agents or a concierge team to respond to customer inquiries via two-way conversation at this time.
  • You need to send SMS in South America, Asia, and/or Africa.

2. Postscript

3. Yotpo

Founded in 2011, Yotpo acquired SMSBump in 2018 to round out its suite of offerings for loyalty and referrals, subscriptions, reviews, and visual user-generated content. The company’s mission is to help ecommerce brands “create better shopper experiences in every way imaginable” across the entire customer journey.

Why you might want to use Yotpo for SMS

Why you might not want to use Yotpo for SMS

  • You need your provider to offer a fully managed SMS program. Yotpo only offers chat support and support from customer success managers. They do have a professional services team, but not for SMS program management.
  • You want access to a broader array of built-in ecommerce integrations. Yotpo offers around 50 for SMS; Klaviyo, for example, offers over 300.
  • You want to consolidate your SMS program with an experienced email provider. Yotpo officially launched email in 2023 and now supports just a few thousand brands. Klaviyo, by contrast, supports email marketing for over 143K brands and has been an industry leader for over a decade.
  • You have advanced segmentation needs, such as including or excluding multiple segments from an SMS campaign. Yotpo does not support this at this time.
  • You need visibility into multi-channel attribution and reporting. Yotpo reports attribution separately.

4. Attentive

Attentive was launched in 2018 as a point solution providing SMS marketing services for midsize to enterprise online retailers. In 2022, Attentive also launched email marketing.

Why you might want to use Attentive for SMS

Why you might not want to use Attentive for SMS

  • You need a self-serve SMS marketing software. Interaction with your Attentive customer success manager and support team is required to accomplish even basic tasks, such as changing your attribution window or scheduling a pop-up.
  • You want access to a broader array of built-in ecommerce integrations. Attentive offers around 100; Klaviyo, for example, offers over 300.
  • You want to consolidate your SMS program with an experienced email provider. Attentive officially launched email in 2023. Klaviyo, by contrast, has been an industry leader for over a decade.
  • You’re not ready to commit to a long-term contract. Month-to-month services are available, but long-term contracts are the default with Attentive. Make sure you understand the full costs, including potential platform fees, additional carriers, and professional services fees.
  • If you send a lot of MMS, Attentive’s pricing might not be the best fit for your brand. Unlike other SMS marketing services—Klaviyo, for example, gives you 1,600 characters, with or without emojis, as part of a single MMS—Attentive gives MMS the same character count as an SMS message (160 characters plain text; 70 with emojis). The result is that the same MMS message may cost slightly more on Attentive.
  • You want to pick the attribution model that makes most sense for your specific business. Attentive’s default SMS attribution model is aggressive: 1-day view, 30-day click. Technically windows are customizable, but only with help from your CSM.
  • You require sophisticated segmentation capabilities. Attentive’s segment builder only supports a few segment conditions, which limits your ability to reach the right people with the right messages.

How to choose the right SMS marketing solution for your business

Keep in mind that when it comes to maximizing your SMS ROI, each text message marketing platform has its own strengths and weaknesses. Selecting the one that’s best for your brand is a daunting process, and a lot of it comes down to asking the right questions.

Choosing the best SMS marketing service for your business depends on what you’re trying to accomplish with your SMS marketing strategy. For example:

  • Are you more focused on engaging customers and potential customers, driving revenue, or both?
  • Does your SMS program cater to specific segments such as VIPs and loyal customers, or does it need to have broader appeal?
  • Where does SMS fit in relation to your email marketing program? For example, do you need the ability to launch hybrid flows that involve both emails and text messages?
  • What kind of SMS marketing attribution model makes the most sense to you?

Before you make your final decision, there are a few text marketing features no business should compromise on. At a minimum, your text messaging service should:

  • Provide built-in SMS marketing compliance in the countries of your interest.
  • Offer short code and toll free numbers.
  • Offer options for multi-step sign-up forms, click-to-text forms, and gathering SMS consent at check-out.
  • Integrate seamlessly with third-party technology.
  • Allow for A/B testing of text campaigns.
  • Provide sophisticated metrics, data and predictive analysis functionality.
  • Enable data capture through actions like browse abandonment and personalization through MMS, dynamic images, coupon codes, and more.

In an economically challenged, data privacy-forward world, where paid targeting is getting less precise and consumers are getting more selective about which brands they deem worthy of their money, SMS marketing is one of the best ways to connect with your audience.

Your SMS marketing platform is what powers it all.

Choose wisely.
