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.

Where to find the built-in GIF editor in Letteros

  1. Open the email editor.
  2. Select the "Image" block.
  3. In the panel on the right, select "Edit" → "Create GIF".

How to create a GIF from images

In the editor:

  • Upload several images (for example, different angles of a product).
  • Set the display order.
  • Set the frame-change speed (for example, 0.5 sec).
  • Save the finished GIF.

Tip: use a maximum of 3–5 frames so as not to overload the email.

How to create a GIF from video

  • Upload a short video clip (up to 10 seconds).
  • Trim the moment you need.
  • Adjust the quality and size.
  • Export the GIF directly to the Letteros media library.

How to insert a GIF into an email

  • Drag the "Image" block to the desired location.
  • Select the created GIF from the media library.
  • Check how it looks on different devices (you can use the preview).

Tips for working with GIFs

✔ Don't exceed a file size of 1 MB — otherwise the email will load slowly.✔ Check how the GIF displays in Outlook (it's better to have a fallback frame).✔ Use animation for key elements, not for the entire email.

Conclusion

The built-in GIF editor in Letteros lets you create great animations without third-party programs — right in the process of working on your email. This saves time, simplifies campaign preparation, and makes your emails more engaging.
