Attentive

Attentive is an SMS and email marketing platform built for e-commerce and retail brands. It uses purchase history, browsing behavior, and other engagement signals to time and target messages to individual subscribers, rather than sending one blast to an entire list. The platform handles list growth (signup forms, pop-ups), segmentation, and automated flows like cart abandonment, back-in-stock alerts, and post-purchase follow-ups, alongside one-off campaign sends.

It's aimed at retail and DTC marketing teams who treat SMS as a direct revenue channel rather than just a notification tool, and who need to coordinate messaging across text and email without annoying subscribers with irrelevant offers. Attentive has leaned heavily into AI features for message timing, send-time optimization, and content generation to help teams scale personalization without manually building out every segment and flow by hand.

What sets it apart is its scale and specialization in retail text messaging specifically, with a large base of e-commerce brands and deep integrations into commerce platforms like Shopify and BigCommerce. It competes most directly with Klaviyo, Postscript, and Yotpo SMS, and is generally viewed as one of the more enterprise-oriented options in that group, with pricing and contracts geared toward larger merchants rather than small independent stores.
