Send Text Messages to Your Customers with Klaviyo SMS


Klaviyo, a marketing automation platform was built to help businesses learn more about their customers and communicate with them on a more relevant, personal level.

The platform now offers SMS marketing to all customers.

What is the value of having SMS and email in one platform?

Ease of setting up an account: Klaviyo doesn’t deal in days or weeks; we work in minutes.

Setting up SMS in Klaviyo requires a single click. You can start sending text messages without lengthy onboarding or contract negotiations.

If you prefer it for your brand, you can provision other code types (e.g. toll-free, short codes or vanity short codes) whenever you want.

SMS Pricing: Paying for SMS in Klaviyo is just as simple as setting it up. First, your first 50 messages are free. Yup, free. This gives you the opportunity to test SMS functionality and gather results before fully committing to it financially. Paying for SMS is also extremely flexible—you only pay for the messages you send. No buying in bulk ahead of time and wasting your hard-earned dollars.

With Klaviyo, you can set automatic refills and spending limits so you always have funds to send messages but never spend more than you want to—the best of both worlds.

Omnichannel solution: By combining SMS and email in one platform you can segment and automate campaigns to send relevant text messages to  customers that help your business grow. 

Our solution is for businesses of all sizes, small or enterprise. You no longer need third-party point solutions that require too much time and too many resources to manage.

With an omni channel service like Klaviyo, you can create and personalize the customer experience across channels—email, push notification, web, and SMS—from a single platform. 

Whether you’re already sending SMS through another platform or looking to add SMS to the mix, Klaviyo can get you up and running in minutes and generate meaningful results.

Customer success: Some customers, like PerfectKeto and Hint, are already experiencing an ROI of over 30x using Klaviyo SMS. On average, customers using Klaviyo SMS also experience click rates of over 25 percent leading to a ton of engagement, website visits, and purchases.

SMS compliance: Before you start sending SMS messages, you should be familiar with the rules surrounding SMS in the U.S. While the specific rules between email and SMS marketing may be slightly different, the core concept is the same: ensure you can acquire and manage consent from your customers before you send them any messages.

The SMS product is built for ease of use.  It will take care of the difficulty of managing every single customer’s consent through the customer’s profile. Klaviyo also makes it easy to seamlessly collect and manage consent from your customers. 

Phone numbers and forms: Before you send, you also need to set up your phone number.

Once that is done use the Klaviyo Form Builder to add a field to a form that collects phone numbers and includes proper consent language for your business.

You can add a phone number block to an existing signup form or build a new form using the form template library.

Klaviyo will automatically store and track the time and source of consent on every customer profile.

You can always see who’s subscribed and be confident you’re only texting with customers who want to hear from you. 

Switching platforms: If you’re coming to Klaviyo from another platform, you can simply upload a list of current SMS subscribers who’ve given you their consent and continue sending text messages to them.

Klaviyo will store consent on their profile and allow you to update profiles with SMS consent—no more wasting time by having to match customer lists in countless spreadsheets.

Best of all, you never have to log into multiple platforms ever again. Klaviyo takes care of consent across email and SMS, removing the risk of communicating incorrectly.  

Efficient marketing:  In Klaviyo, you can simply drag in the split and add a text message. The split criteria can check to see if the recipient has opened your prior email. If not, they’ll receive the follow-up text message as long as they’re subscribed. 

By sending a second message to non-email openers via SMS, you increase the number of conversions and/or engagement with every automation you build.

You can also improve your overall brand experience using SMS in automations

Customers often desire order, shipping, and delivery confirmations, so they’re a great way to get customers to subscribe. As part of your opt-in language, you can include the fact that they can expect to receive other promotional offers in addition to the transactional messages.

Test your text messaging campaigns: You can test out sending product offers and flash sales via a text message campaign. This is a great way to acquire subscribers and then use text messages to sell more of your products in ways that people love to receive communication. 

All of these messages can be personalized with relevant data about your customers in just a few clicks.

Just like you can create dynamic emails, you can use the same logic in SMS messages.



Data Science: Klaviyo is where you go to grow. We know how important it is for you to test, learn, and improve quickly, and we’re excited to bring that power to SMS.
