Alterable
Add live, personalized images to any email. Rendered fresh at open time, no code, works with any ESP.
About Alterable
Alterable adds content to marketing emails that is rendered at the moment each email is opened rather than when it is sent. Its services include countdown timers, dynamic images drawn per reader, dynamic products priced at open, local maps to the nearest store, slideshows, polls, surveys, scratch-card giveaways and critical message banners that can be switched on after a send.
Users design an image in a visual builder, set rules such as a deadline or what to show when data is missing, then paste a single image tag into their email template and swap in their ESP's merge tags. It works with Klaviyo, Mailchimp, HubSpot and any platform that sends HTML email. Content is delivered as standard images with no JavaScript, and sending domain authentication is unchanged.
Alterable is aimed at brands running flash sales, abandoned cart, loyalty and local store campaigns, as well as agencies, who can give each client its own team with a separate ESP, images and teammates on one plan.
