Quick answer
How do I add an animated GIF to my email signature?
Open your mail client's signature settings, put the cursor below your contact details, insert the GIF as an image, then select it and add a hyperlink to the page you want people to visit. Save, and send yourself a test email. The GIF is inserted exactly like a static image — the only variable is whether the reading client animates it.
Key facts
- Insert method
- Add the GIF as an image in the signature editor — there is no separate animation setting.
- Gmail
- Settings → See all settings → Signature → insert image, then add the link.
- Outlook
- File → Options → Mail → Signatures, or Settings → Compose and reply on the web.
- Hosting
- Gmail can hold the image itself; Outlook is more reliable when the GIF is hosted at a public URL.
- Common failure
- Pasting a still screenshot of the GIF instead of the GIF file.

Before you insert anything
- 1Export your banner as a GIF at the size you designed it — do not plan to resize it later.
- 2Have the destination URL ready; an unlinked banner wastes the click.
- 3Check the first frame reads on its own, in case the animation is blocked.
Platform instructions
Adding your banner in Gmail
- 1Click the gear icon, then See all settings.
- 2On the General tab, scroll to Signature.
- 3Select an existing signature or create a new one.
- 4Place the cursor beneath your contact details and use the insert-image control in the signature toolbar.
- 5Upload the GIF from your computer, or select it from Drive if you keep assets there.
- 6Click the inserted image, then use the link control to add your campaign URL.
- 7Scroll to the bottom and click Save changes, then send a test email to yourself.
Gmail typically animates GIFs in signatures. If the image is too large, go back to the editor and export a smaller canvas instead of dragging the image handles.
Testing properly
A signature looks correct in the client you built it in almost by definition. The useful test is receiving it somewhere else.
| Test | What it tells you |
|---|---|
| Send to a Gmail address | Whether the animation plays in the most common consumer client. |
| Send to an Outlook address | Whether your first frame is doing its job. |
| Open on a phone | Whether the text is still readable at reduced width. |
| Click the banner | Whether the hyperlink survived being saved. |
| Reply to the test | Whether the banner repeats awkwardly in long threads. |

GIF not working?
- Only the first frame is showing
- The reading client is rendering the GIF as a still. Several Outlook builds and some corporate mail configurations do this. You cannot force it from the sender side, so make the first frame self-sufficient.
- Animation is disabled by a system setting
- Reduced-motion and accessibility settings can stop animated images playing. Again, the first frame is your fallback.
- The file is too large
- Big GIFs load slowly or get stripped by some gateways. Reduce animated elements, shorten the loop or simplify the background.
- It was inserted the wrong way
- Pasting a preview or linking to a temporary URL often produces a broken image later. Insert the file through the signature editor's image control.
- The image is cached
- If you replaced a banner and still see the old one, the client may be showing a cached copy. Test with a fresh message or a different address.
- Formatting is being stripped
- Plain-text mode removes images entirely. Confirm the signature is used in rich-text / HTML composition.
Email client support
Animated GIFs are supported by most modern mail clients. The important exception is Outlook for Windows (classic), which shows the first frame as a still image.
| Email client | Animated GIF | What to expect |
|---|---|---|
| Gmail (web, iOS, Android) | Plays | The GIF animates and loops as exported. Images may be proxied and cached by Google. |
| Apple Mail (macOS, iOS) | Plays | Animation plays. Wide banners are scaled down to the message width on iPhone. |
| Outlook.com / Outlook web | Plays | Animation plays in the browser client. |
| Outlook for Windows (classic) | First frame only | The GIF is shown as a still image using frame one. Nothing is broken — the message just has to work without motion. |
| Outlook for Mac / new Outlook | Plays | Animation plays in current builds. |
| Yahoo Mail, Superhuman, Spark | Plays | Animation plays; the banner is scaled to the reading pane width. |

Common questions
Some Outlook versions render animated GIFs as a static first frame. This is client behaviour rather than a fault in your file, which is why the first frame should contain your core message.
