SMS Assistant AI Text Messages
SMS Assistant AI Text Messages is Klaviyo's built-in copywriting tool for SMS campaigns. You open it from the SMS campaign editor, pick a campaign type, describe your promotion or product, and it returns three ready-to-send text options in seconds. It lives inside Klaviyo's marketing platform, so the copy lands directly in your campaign workflow without switching tools.
Most SMS copy generators are standalone apps that hand you text and leave compliance as your problem. Klaviyo's SMS Assistant is trained on carrier regulations and blocks forbidden content before you send, which matters because a rejected message costs you a segment and a subscriber's trust. The trade-off is you need a Klaviyo account with SMS enabled; this is not a free standalone writer.
Ecommerce marketers, SMS specialists, and growth teams at retail brands use it to draft promotional texts, product launch announcements, and newsletter-style SMS without spending hours on character limits and compliance wording. It fits teams that already run email and SMS from Klaviyo and want faster first drafts inside the same editor.
