How to Add an Animated Email Signature in Gmail and Outlook

An animated email signature usually places a GIF beside your name and contact details. You add it through your email client's signature settings, but the useful check comes afterward: send an email and look at what arrives. A signature that moves in the editor may appear as a still image for a recipient.

Add a GIF to your email signature

Start with the original animated .gif file. Open it before inserting it to confirm that it plays, and inspect its first frame separately. If your logo fades in from an empty frame, change the opening so a static version still shows the logo.

Resize and compress the file before adding it to the signature. Check that the lettering remains legible at its intended display size; reducing its dimensions in the signature editor is not a substitute for reducing a large file. Use an animation you own or have permission to include in your emails.

Add the signature in Gmail on a computer

Use Gmail in your desktop browser for these steps. Google's signature instructions explain the settings and how to choose a default for new messages and replies.

1. Open Settings > See all settings. Under General, scroll to Signature.
2. Create a signature or select the one you want to edit, then add your contact text.
3. Put the cursor where the GIF belongs and use the image button. Upload the file, select it from Drive, or provide its public image URL using the options available to your account.
4. Choose the signature defaults for new emails and replies or forwards.
5. Select Save Changes at the bottom of the settings page. Open a new message and check that the intended signature appears.

If an image is missing, check its sharing and upload method. Google's signature troubleshooting guide explains the available image sources and the public-sharing requirement for Drive images. A private image that you can see while signed in may be unavailable to a recipient.

When creating an animated email signature with MySignature, keep contact details outside the animation and make sure the first frame is useful on its own. Send the finished email to check the result across clients.

Add the signature in Outlook

Choose the instructions for your Outlook app. Microsoft's signature guide covers new Outlook, classic Outlook for Windows and Outlook on the web.

New Outlook for Windows and Outlook on the web

1. Open Settings > Accounts > Signatures and select the sending account if prompted.
2. Choose Add signature, give it a name and enter your contact details. Use the editor's image control to insert your GIF.
3. Choose whether to include it in new messages and replies or forwards, then select Save.

Classic Outlook for Windows

1. Open a new email and choose Signature > Signatures from the Message menu.
2. Select the email account, create or select a signature, and enter your contact details.
3. Use the Image button to insert the GIF. To resize it, right-click the image, choose Picture > Size, and keep Lock aspect ratio selected.
4. Set the defaults for new messages and replies or forwards, then select OK. Open a fresh message to check the saved signature; the message used to create it may need the signature added manually.

Repeating the layout check across several apps means opening the same message in each one and comparing the results. MailSlurp is an email testing platform with device previews that capture the delivered email across selected clients and devices, making it easier to compare image size, text wrapping and spacing.

Which email clients support animated GIFs?

The exact app, version and recipient settings matter more than a blanket "Outlook supports GIFs" answer. Microsoft documents GIF playback in Outlook for Microsoft 365, Outlook 2024 and Outlook 2021, while disabled animations can leave only the first frame visible. Its troubleshooting instructions distinguish older Outlook controls from Windows animation settings.

Include the phone app in your checks if you send from or to mobile devices. Compare the email that arrives there with the desktop version, rather than assuming one successful desktop test covers both.

Test the signature in a received email

Send a short message from the account and app where you installed the signature. Include ordinary body text above it so you can judge the spacing between the message and the sign-off. Test a new message and a reply, since those can use different signature defaults.

Open the received email in the clients you need to support and check the following:

• Image and text: the GIF loads at the intended size, and the name, phone number and website remain readable on a narrow screen.
• Animation and fallback: watch the received GIF to check playback, then inspect the first frame on its own. A screenshot helps assess layout but cannot establish that the animation plays through correctly.
• Links: click the website, booking and social links from the received message. Check the destination even if the visible label is correct.
• Replies and missing images: reply to the message, inspect any repeated signature, and check that contact details still make sense with images hidden.

For a walkthrough of comparing the complete email in different Outlook clients, follow the Outlook rendering guide. If only the signature is missing, first check the selected sending account and its new-message or reply default. If the image alone is missing, check the image source and access permissions before rebuilding the signature.

After a correction, save the signature and send a fresh message from each app you use. Reopen that new email to verify the change; an older message will still contain the signature it was sent with.
