Animation in emails is a great way to make your campaigns stand out, feel more alive, and boost engagement. But not everyone knows that Letteros has a built-in GIF editor that lets you create and edit GIFs right inside the builder.
Today we'll show you how to do it quickly and easily!
Why use GIFs in emails?
✔ Grabs attention — animated elements stand out more than static ones.✔ Conveys emotion — you can show a product in action or add dynamics.✔ Saves space — a short GIF replaces a long explanation.
Important: don't overload your email with GIFs, or it will load slowly.

Tips for working with GIFs
