How to change your Gmail signature

Open Gmail in a web browser, click the gear icon in the top right, and select See all settings. Scroll down to the Signature section, click in the text box, delete your old signature, type or paste your new one, and click Save Changes at the bottom of the page. The new signature will appear on all emails you send going forward, but won't change signatures on emails you've already sent.

If you use Gmail on your phone or tablet, you cannot edit your signature in the mobile app itself. You'll need to open Gmail in your phone's web browser, follow the same steps above, and the change will sync to your app. Gmail's mobile app only lets you turn signatures on or off, not create or edit them.

Key Takeaways

  • Gmail signatures are edited through Settings, not from the compose window, and the change takes effect on all future emails.
  • You can use text, links, images, and basic formatting in your signature, but the mobile app cannot edit signatures—use a web browser instead.
  • If you have multiple Gmail accounts, each account has its own signature, and you can set a different signature for each one.
  • Signatures do not retroactively change on emails already sent; only new emails from that point forward will include the updated signature.

Step-by-step: Desktop browser

Start by logging into Gmail at gmail.com. In the top right corner, click the gear icon and select See all settings from the dropdown menu. This opens the full Settings page.

Scroll down until you see the Signature

Once you're satisfied with your new signature, scroll to the very bottom of the Settings page and click the Save Changes button. Gmail will confirm the save. Close the Settings tab and return to your inbox—your new signature is now active.

Adding formatting and images to your signature

The signature text box includes a small formatting toolbar. You can make text bold or italic, change the font, adjust text color, and add links. To add a link, highlight the text you want to link, click the link icon in the toolbar, paste the URL, and click Apply.

To insert an image, click the image icon in the toolbar. You can upload a file from your computer, paste a URL, or search Google Images. Keep images small—large logos or photos can make your signature unwieldy and slow down email loading. Most people use images only for company logos or small headshots, typically under 100 pixels wide.

Setting different signatures for multiple Gmail accounts

If you have more than one Gmail account, each one has its own signature setting. Log into the first account, set its signature through Settings, then log out. Log into your second account and repeat the process. Each signature is stored separately and will only appear when you send from that account.

When you're composing an email in Gmail and you have multiple accounts, you'll see a dropdown menu showing which account you're sending from. The signature for that account will automatically appear at the bottom of the compose window.

Why your signature isn't showing up

If you've set a signature but it's not appearing on your emails, first check that you actually saved your changes—scroll to the bottom of Settings and confirm the Save Changes button was clicked. If it was, refresh your browser and try composing a new email to see if the signature appears.

Another common issue: if you have the signature setting turned off in the mobile app, it won't show on emails sent from that app, even though it's saved in Settings. Open the Gmail app, tap your profile picture, go to Manage your Google Account, then Personal info, and check that signatures are enabled. On desktop, signatures are always on once you've saved them.

Removing your signature

To remove your signature entirely, go to Settings, scroll to the Signature section, click in the text box, select all the text, and delete it. Leave the box empty and click Save Changes. Your emails will no longer include a signature.

If you want to keep a signature saved but temporarily turn it off, you can do this in the Gmail mobile app by disabling the signature toggle. On desktop, there's no toggle—you either have a signature or you don't.

Frequently Asked Questions

Can I have different signatures for different types of emails?

Gmail's built-in settings don't support multiple signatures within one account. However, if you use Gmail for both work and personal email, you can create a second Gmail account with its own signature, or use a third-party tool like Boomerang or Gmail's native templates to set up different signature options.

Will my signature appear on emails I forward or reply to?

Yes. When you reply to or forward an email, your signature will appear at the bottom of the message, below the original email thread. This is standard behavior and cannot be changed in Gmail's settings.

Can I use HTML code in my signature?

Gmail's signature editor doesn't accept raw HTML. Use the formatting toolbar instead to add bold, italics, links, and images. If you need advanced HTML formatting, you may need to use a third-party email client or tool that supports custom HTML signatures.

Does my signature take up storage space in Gmail?

No. Your signature is stored in your account settings, not in your email storage quota. It won't count against your 15 GB of free storage.

What happens to my signature if I change my Gmail password?

Your signature remains unchanged. Changing your password does not affect any of your Gmail settings, including your signature.
