Create a Gmail signature
An email signature is text, like your contact information or a favorite quote, that’s automatically added at the end of Gmail messages as a footer.
Add or change a signature
You can put up to 10,000 characters in your signature.
- Open Gmail.
- In the top right, click Settings Settings.
- In the "Signature" section, add your signature text in the box. If you want, you can format your message by adding an image or changing the text style.
- At the bottom of the page, click Save Changes.
Add a signature if you're using the "Send mail as" feature
If you use the "Send mail as" feature to send from different addresses in your account, you can add a different signature for each address.
To select an address, use the drop-down menu above the signature text box on the Settings page.
If you don’t see the drop-down menu:
- Open the Accounts and Import settings page.
- Check that your addresses are listed in the "Send mail as" section.
If you notice extra characters in your signature, it's because some versions of Gmail don't support features like bolding or italics.
To remove the extra characters, remove any special formatting in your signature.
If you see "Plain Text" above the signature box, you need to turn off Plain text mode before editing your signature.
- Open Gmail.
- Click Compose.
- In the bottom right, click More options .
- Uncheck "Plain text mode."
Signatures are separated from the rest of your message by two dashes.
To see your signature, go to the bottom of a message, then click Show trimmed content .
- If you added a photo or image from Google Drive, you'll need to share your image publicly for it to appear in your signature. Note: If you use Gmail with your work or school account, ask your administrator to let you share images publicly.
- Search for an image, like your company logo, then get the image URL.
- Add your own image to Google and use that URL.
