Klaviyo SMS Assistant

Klaviyo SMS Assistant is a copywriting tool. An AI copywriting assistant inside Klaviyo's SMS campaign editor that turns a short brief and a campaign type into three compliant text message drafts, two single-segment and one two-segment, in seconds.

Klaviyo SMS Assistant is an AI copywriting feature that lives inside the Klaviyo SMS campaign editor. Instead of staring at a blank message field, a marketer selects a campaign type, adds a short brief, and receives three ready-to-edit SMS drafts within seconds. The assistant is tuned for the constraints of text messaging, where brevity and carrier compliance matter more than in almost any other marketing channel. The workflow is deliberately narrow. Four campaign types are offered: Promotion, Product Announcement, Newsletter, and Other. Choosing one shapes the vocabulary of the output, so a Promotion brief leans toward urgency and sales language. The brief itself takes an optional product name plus a free-text description of the campaign. The assistant then returns two shorter messages sized to a single SMS segment and one longer message that spans two segments. Clicking any suggestion appends it to the existing editor content rather than overwriting it, so partial drafts survive. Compliance is the feature's main differentiator. Klaviyo states the assistant is trained to avoid forbidden SMS content and to align with mobile carrier regulations, which is a meaningful safety net for brands entering text marketing for the first time. The vendor positions it primarily for those newcomers, though experienced SMS marketers can use it as a starting point for iteration rather than a finished product. It is not a standalone tool. There is no separate app or free tier: the assistant only exists for Klaviyo customers sending SMS campaigns to predefined segments. That makes it a convenience layer on top of an existing CRM rather than a reason to switch platforms. Brands already on Klaviyo get a fast first draft and a compliance check; everyone else is looking at the cost of the full platform.
