GIF animation in emails boosts click-through rate, holds attention, and makes a specific block stand out among static content. There are plenty of tools for creating one, but each has its own purpose.

If you need an animation for a messaging app or a social media post, pretty much any service will do. If you need one for an email newsletter, though, the choice becomes clearer: what matters is file size, compatibility with email clients, and how the animation gets embedded in the email. Let's break down three popular options — Giphy, Ezgif, and Letteros.

Giphy

A catalog of ready-made animations. Go in, find something suitable, download it or copy the link. No sign-up, no settings.

Giphy is built for messaging apps and social media. Ready-made animations from the catalog rarely fit an email's brand style. You can upload your own image, but editing is minimal: cropping, speed, size — and that's it.

What it can do

What it can't do

Quickly search ready-made animations

Create animation matching your brand style

Download a file without signing up

Add text, a logo, or brand colors

Basic cropping

Control file size for an email

Best for: quickly finding a ready-made animation for a messaging app or social post. Not suitable for email.

Ezgif

An online editor and converter. Upload a set of images and get an animation out. There are more tools: frame order, speed, file-size optimization, adding text, stitching multiple animations together.

For those who understand how animation works at the frame level, Ezgif is a solid working tool. But two drawbacks remain for email tasks.

First: the interface takes some figuring out. A beginner will spend time on settings instead of getting results.

Second: Ezgif knows nothing about email. It won't tell you the acceptable file size for an email, won't check whether the first frame reads clearly in email clients, and won't warn you about Outlook's limitations.

What it can do

What it can't do

Build an animation from a set of images

Optimize for email clients

Edit frame order, speed, size

Show how the animation looks inside an email

Optimize file size manually

Fit into the email-building workflow

Add text over the frames

Account for Outlook's limitations

Best for: one-off tasks — you have a set of images and need to build an animation. Not convenient for regular newsletters.

Letteros

Letteros has an animation editor built right into the email builder. It's simple: upload a few images, set the order and speed of the frames, and you get a finished animation — all within the same interface where you're building the email.

No third-party services, no switching between tabs. Make the animation, drop it into an image block, check it in preview.

A few practical rules for working with the editor:

— Use 3–5 frames. More than that, and the email will take longer to load.— Keep an eye on file size: ideally under 1 MB.— Check the first frame separately. Outlook doesn't play animation, so the reader will only see that one. The first frame needs to make sense on its own.

What it can do

Limitations

Build animation from images inside the builder

Builds from images, not video

Adjust frame order and speed

Requires a Letteros account

Insert the result straight into the email

Check the result in preview

Best for those who send newsletters regularly and don't want to build animations in a separate service every time.

Giphy and Ezgif are standalone tools, disconnected from the newsletter-building process. After creating an animation, you have to separately check it for compatibility with email clients and manually insert it into the email. In Letteros, the whole cycle — from uploading frames to the final email — happens in one interface.
