As an email marketer, you’re always trying to improve your campaigns through the use of copy, design, personalization, artificial intelligence, and beautiful images. But with so much competition for subscribers’ attention, you need to get creative about how to entice readers to click through and care about your message. Enter: Animated GIFs in email.
Email marketers are increasingly turning to animated GIFs in email to provide extra visual interest in their messages and according to our 2023 State of Email Design Report, 58% of marketers said they’re using animated GIFs in their marketing emails and 43% said there was somewhat of an improvement in email performance when GIFs are used.
So how can you get in on this action? In this blog post, we’ll cover:

What is an animated GIF?
GIF, which stands for Graphics Interchange Format, is an image format developed by CompuServe in 1987. Due to wide support across browsers and email clients, GIFs have been a popular image format since the early days of the internet.
More importantly, though, GIFs can be animated. Similar to how a flipbook works, GIFs rapidly display a series of images to produce the illusion of motion. In the internet’s early years, GIFs (and the marquee and blink tags) were the primary method of adding movement to a web page.
A lot has changed since the 1990s. Animated GIFs are enjoying a renaissance both on the web and in email marketing. While there is still some debate as to how you actually pronounce “GIF,” most will agree that GIFs can be an excellent marketing tool.
What are the benefits of animated GIFs in email?
Whether you prefer a hard “G” or like to rhyme GIF with a certain brand of peanut butter, let’s look at why GIFs are so useful in emails.
Adding animation in email with a GIF is a great way to grab your subscribers’ attention, point them toward an action you want them to take, or keep them scrolling to make sure they get your whole message.
Grammarly uses a very subtle animation to draw attention to their offer leaving you wanting to spend more time reading—and hopefully—taking action on the email.
2. Show off your products and services
You know your product is great. Make sure your subscribers know it, too. There’s nothing like an animated GIF to show off how your product or service works.
ILIA Beauty showcases their product in action with real people.
3. Simplify a complex idea
If a picture is worth a thousand words, then an animated picture is probably worth even more. Use an animated GIF to illustrate a complex idea or show your subscribers that things are even easier than they think.
Baggu took simple cleaning directions to the next level by animating them. By making four different animations, the subscribers have to scroll to see the whole story.
4. Tease something new or coming soon
Do you have some new content or product you’re about to release? Have a great offer coming out soon? Use an animated GIF to create awareness or interest in your product—and have subscribers looking out for your next email.
Linus’ electric bike is just hinted at in the shadows in this email. Subscribers will have to click through to see the actual product.
5. Draw attention to your call-to-action
Animated GIFs can be used to draw subscribers’ to a certain action you want them to take.
Pond5 uses an animated GIF to draw attention to the email’s primary call-to-action (CTA), “Download free clip.”
6. Adds personality
We used the faux video technique to create an animated GIF of a video featuring us to help add some authenticity and personality to a seasons greetings email.
Considerations when using animated GIFs in email
As is the case with most things in email, there are some very specific considerations you need to think about when using animated GIFs in email.
Animated GIFs are supported almost everywhere. In 2019, Outlook expanded its support for animated GIFs, but this only affects Office365. Outlook 2007-2019 still don’t support animated GIFs.
Here’s a quick chart of which email clients do and don’t support animated GIFs:
To maintain a great experience where animated GIFs are not supported, be sure to make the first frame contain everything you need as a static fallback.
You could also provide a fallback for Outlook by hiding the normal GIF image and displaying a static image and/or different content inside Outlook conditionals:
<!--Animated Version for everywhere else-->
<!--[if (gte mso 9)|(IE)]><!-->
<img src="YourAnimatedFile.gif" style="display: block; padding:0; margin:0; height: auto; max-width: 100%;" border="0" alt="" width="538" height="269" />
<!--Static Version for Outlook-->
<!--[if (gte mso 9)|(IE)]>
<img src="StaticVersion.gif" style="display: block; padding:0; margin:0; height: auto; max-width: 100%;" border="0" alt="" width="538" height="269" />
When it comes to email client support: it’s helpful to know which email clients are popular with your audience. If Outlook 2007-2019 is a top client with your subscriber base, take the time to ensure your fallback is working as planned.
(Also, it might be a good idea to use a solution like Email Guardian to look out for any broken emails before hitting the send button!)
You can test load times with a tool like Litmus’ automated pre-send testing checklist to see if your images are taking too long to load. On average, we’ve found that just over half of recipients only spend less than two seconds on an email. So your animated GIFs need to load fast to make an impression.
We tested different file sizes to find their average loading speeds over different connections. On average, a 4.4MB animated GIF can take over two times longer to load over a 4G LTE connection than over an Ethernet connection.
Here are some average speeds for different file sizes on different connections based on our own experiment:
Average content download speed (in seconds)
These times are the content download speed and don’t take into account the time to first byte (TTFB). TTFB is a way to measure the responsiveness of a web server. So if you’re hosting your images on a server that is slow to respond, the load times for the animated GIFs would increase for your subscribers.
On top of slower load times, animated GIFs with larger file sizes will also use up data faster, which your subscribers probably won’t be happy about.
Since you don’t have control over your server speed, your subscriber’s connection, or your subscriber’s data plan, it becomes extremely important to make sure that your animated GIFs are small enough to ensure that your audience can view it no matter where they’re opening your email. We recommend 1MB at the largest.
Animated GIFs can pose a problem in terms of accessibility for a variety of reasons.
Content flashing rates between 2 Hz and 55 Hz can harm users with photosensitive epilepsy. In addition, users who are visually impaired may have difficulty reading or reviewing content on a GIF before the animation changes. So, ensure your animated GIFs either have smooth transitions or don’t animate from one frame to the next at a high rate.
And, since GIFs are image files, you should always include appropriate alternative text for users who rely on assistive technology like screen readers. Images are inherently inaccessible for a lot of people, so providing copy and context allows them to understand your message more clearly.

If you need to bring more color or some background transparency to your animated content, then an animated GIF may not be the way to go.
GIFs are not graceful when it comes to transparent backgrounds. But, you can bring an animated alternative to email in the form of an animated PNG (APNG). Be sure to take note of the same compression tips and tricks we share next since APNGs also like to pile on the kilobytes (KB).
And if you’re looking for yet another alternative to animated GIFs, you might want to explore CSS animations.
How to add Animated GIFs in an Email
Adding an animated GIF to your email is exactly the same process or code that you’d use to embed any other image file into your email:
<img src="http://yourwebsite.com/path/to/awesome.gif" width="100" height="100" alt="Description of your gif”>
But how do you go about creating an animated GIF?
How to create animated GIFs for emails with Adobe Animate
You can create GIFs in a number of ways. Online makers allow you to animate a selection of photos or turn a video into an animated GIF, or you can use software such as Adobe Photoshop or Adobe Animate to make custom designs move.
Here’s an overview of how to make an animated GIF in Adobe Animate. (Our animated GIF creation progam of choice.)
Step 1: Create a new file and input dimensions
To make a GIF in Adobe Animate, first create a new file and input the dimensions you would like this to be. Pro tip: Create your animation at twice the size for retina display, just as you might for static imagery.
Step 2: Import the graphics to be animated
You can design your animation directly onto the canvas, using the software’s shape and drawing tools, creating a layer for each element. If you created the design for your animation in Adobe Illustrator, you can simply copy and paste your vector graphics onto your canvas. Otherwise, you can import graphics into Adobe Animate by going to file > import > import to stage. Or if you’re importing a graphic that will be reused multiple times, you can “import to library.”
Step 3: Create your animation
Now you can use the timeline to create your animation. There are a lot of possibilities with software like this, and it would be hard to touch on all of these in a single blog post. However, there’s a wealth of resources out there with many helpful guides on YouTube, in Adobe’s online tutorials, and within the software itself.
I would recommend paying particular attention to content around symbols, tweening, and ease. With these three functions alone, you can create highly engaging animation that helps grab attention, push your message, and delight your audience. All while bringing buckets of brand personality to your emails.
A symbol is a graphic, button, or movie clip that you create once and then re-use by selecting it from the library.
Once you’ve created a symbol, you can re-use it within your animation—this is called an instance. If you were to edit your symbol, such as by changing the color, it would be made across all instances (similar to email partials). But if you were to edit an instance, your change would only apply to that one instance.
For animated GIFs, we suggest only converting your design elements to graphic symbols. Both movie clips and buttons have their own timeline attached to them, so you can animate them independently of the main timeline. However, as any animations created outside of the main timeline aren’t honored when you export your animation as a GIF, it makes sense to stick with graphic symbols which only animate on the main timeline.
Tweening is how you animate from one state to another. You can use either shape, motion, or classic tweens.
A shape tween can only be used with shapes or elements that you’ve drawn on to either the canvas or vectors imported using AI importer preferences (rather than as a bitmap). This is because a shape tween enables you to alter the shape of an object. For example: You could add a circle to one keyframe on your timeline, add a square on another, then morph your circle into your square with the shape tween.
Motion tweens are used to create animation movements by specifying different values between the first and the last frames. With this kind of tween, you can alter an object’s properties—including position, size, color, effects, filters, and rotation.
Classic tween is very similar to motion tweening. It was carried over from Flash and is retained within Animate as an additional option. This is my preferred way to apply motion tweening, as easing techniques (discussed below) are a little more straightforward to apply.
Easing goes hand in hand with tweening. If moving an object from one position to another using the timeline is the cake, then easing is the frosting!
Using Animate’s ease functionality, you can make the tween accelerate or decelerate at the beginning or end. Or add a little bounce when the tween completes. This really helps bring some personality to your animation.
The ease applied to this tween starts the animation quickly and slows at the end.
In this example, we applied a bounce-in ease to the tween.
For information on how to apply easing check out this video on YouTube.
Step 4: Export your animated GIF
Saving your animation out of Adobe Animate as a GIF is nice and simple. Just head to File > Export > Export Animated GIF.
How to optimize your GIF for email
Regardless of whether you use Adobe Animate or something else—keeping your GIF size for email down is crucial for email. There are a few things worth considering to help you keep your animations as light as possible.
Tools like Animate and Photoshop have limited compression options for GIFs; it’s often better to use external software instead for compression. We recommend ImageOptim, which is free to download, or EZgif, a free online GIF optimizing tool, to get your file size down to its optimum weight. We recommend keeping the size below one megabyte (MB), but the optimal file size will vary and depends on email load time.
Including photography or gradients in your animation adds weight due to the amount of colors and shades these contain. A GIF can only contain 256 colors—compared to a JPEG which can include upwards of 16 million—which often results in the quality taking a hit. Keeping things simple is key.
The shorter the animation, the better. Each frame your animation contains adds weight to the GIF. Since an animation should really be about complimenting your copy, limit how long your animation plays and encourage readers to move down the email.
If you find that your GIF is carrying a little too much weight after saving and compressing, you can remove frames using Photoshop or EZgif.
Proofing your animated GIF
Now that you’ve created your GIF, you may want to get feedback or approval before placing it within your email. With a real-time collaboration tool like Litmus Proof, you can centralize everyone’s comments and approvals.
