Email Countdown Timer
Alterable
Personalized email images, rendered at open time.
Alterable generates images for your emails at the moment each subscriber opens them. Add a countdown timer that ticks in real time, swap a hero image based on the reader's device, location, weather, time of day, or language, show a map of their nearest store, or drop in a scratch-and-win card or a one-click survey. Build the image, set the targeting rules, and paste one line of HTML into any email platform that lets you edit HTML, including Mailchimp, Klaviyo, HubSpot, and Brevo. Automate with Zapier, Make, or the API, and connect Claude or ChatGPT through the MCP server. No code.

Hey all, Matt here, I built Alterable. Started as a countdown timer for emails and grew into a full open-time image engine. Happy to answer anything about how the rendering works or what to build next
