Overview

Alterable replaces the static images in your email campaigns with images generated the moment each recipient opens the message. Setup is one image tag: design it in the editor, paste the embed code into Mailchimp, Klaviyo, HubSpot, Braze or any platform that supports HTML images, and send as usual.

At open time, Alterable uses the current time, device, location, local weather and language to render the right image for that reader. You set the rules and a default covers everyone else.

Building blocks include countdown timers that stay accurate on every open, dynamic images and products that change with targeting rules, maps to the nearest store, scratch-and-win cards and one-click surveys that work inside the inbox. Each image reports impressions by device, country and time of day.

Developers get a REST API, Zapier and Make apps, and an MCP server for AI assistants. Free plan available at alterable.com.

Dates show when a record was saved. Some older records use the listing’s update date; they are not proof of a fresh check. Missing source records are shown explicitly.
