How It Works
Design once. Personalize for everyone.
No developers. No integrations. Build your image in Alterable’s editor, set your rules, and paste one URL into your ESP.
Design your image
Use the built-in canvas editor to create your base image. Add text, shapes, logos, and background photos. Full control over fonts, colors, sizing, rotation, and layering.
Set your targeting rules
Define conditions: show image A in London in winter, image B on mobile in the morning. No code required. Filter by location, device, language, time of day, weather, date, and more.
Embed and send
Copy a standard <img> tag into your ESP. Each recipient gets the right image, rendered fresh on open.
<img src="https://img.alterable.com/summer-sale" />Track impressions and rule performance in real time.
Targeting Rules Engine
Decide exactly who sees what. Without writing a line of code.
Alterable’s visual rules builder lets you stack conditions and map each combination to a different image variation, all from a drag-and-drop UI.

Questions about dynamic images
How does Alterable decide which image to show?
You stack conditions in the rules builder (location, device, language, weather, temperature, time of day, date, momentum or a query parameter) and map each combination to a variation. The rules are evaluated at the moment the email is opened.
What if none of my rules match?
The default variation is shown. Every subscriber gets an image; nobody sees a broken one.
Does it work in every email client?
Yes. Each dynamic image is an ordinary image tag pointing at one URL. There is no script and nothing for a client to block beyond images themselves.
Do I need to re-send the campaign to change the image?
No. The image resolves each time the email is opened, so updating a variation or a rule changes what readers see in mail that has already landed.
How many languages does it support?
Language targeting covers 22 locales, so one send can carry the right copy on the image for each of them.
