Klaviyo is a marketing automation platform designed to help you engage with your customers where they are most active. Whether it’s over text or emails, it connects you with your most valuable customers faster. This CRM for texting includes features like subscription links, MMS, cross-channel automation, and more to help you build and strengthen customer relationships.
With Klaviyo, adding customers to your sales pipeline is easy. It allows you to create shareable SMS subscribe links so you can gather new sign-ups through email CTAs, social media campaigns, and QR codes. And since many of your customers will be on mobile, Klaviyo provides dynamic text blocks that allow you to create one SMS sign-up form that automatically optimizes for mobile visitors.
Once you have your list you can start sending prompt, personalized text messages in response to customers’ real-time behavior and data. Automating these responses is easier with the CRM’s 20+ prebuilt automation flows for multiple scenarios.
But what truly simplified the text messaging automation when we tested Klaviyo was its drag-and-drop flow builder. It is not only easy to use but also gives you complete control over your message sequences, allowing you to easily lay out each of your automation.

That’s not all. Like Shape, Klaviyo ensures your texts are personalized by properly segmenting your customers. It has a segment builder that allows you to group your list and send your messages based on factors like predicted lifetime value, previous purchases, discount code usage, and other data. These segments update in real time so your messages are always relevant.
Klaviyo does not just send messages, it supports 2-way conversations by allowing you to respond to each customer in real-time whether directly through the CRM or through third-party integrations with Gorgias and Zendesk.
As expected from any credible CRM for SMS, Klaviyo is compliant with texting regulations across several countries, including GDPR, CCPA, TCPA, and PECR, as well as the Canadian, Australian, UK, and New Zealand Anti-spam legislation.
Its SMS delivery technology operates via API which ensures seamless integration and reliable message delivery. This also supports the platform’s broad compliance with several texting regulations.

Unlike several other providers we tested, Klavioy’s carrier fees are built into its pricing so before sending your messages, you know exactly how many credits you’ll use. However, this cost can run high causing several small business and startup users to point this challenge out in reviews.
Credit costs per text message vary with location. For example, users in the US require 1 credit per SMS and 3 per MMS while those in Canada require 3 credits per SMS and 5 per MMS.
When you are starting, it offers a generous free plan perfect for getting familiar with all the workings of the CRM. The free plan includes 150 free monthly SMS/MMS credits and any applicable carrier fees.
Subsequently, you can upgrade to the E-mail and SMS plan that starts at $45 for up to 1500 contacts, 150 SMS and MMS credits, and at least 15,000 monthly email sends. This fee increases as you add more credits.
Altogether, Klaviyo shines for its auto-segmentation for efficient targeting, comprehensive SMS templates, as well as its built-in carrier fees. However, one major drawback is that message credits do not roll over. You can only use them within the designated period which is not ideal considering the high cost. Also, if your business operates in several geographical locations, configuring settings like opt-ins can be difficult.
