Change your Gmail signature in Settings

Your Gmail signature appears at the bottom of every email you send. To change it, open Gmail, click the gear icon in the top right, select See all settings, then scroll down to the Signature section. Delete the old text, type or paste your new signature, and click Save Changes at the bottom of the page.

The signature section sits about halfway down the Settings page. You'll see a text box where you can type directly or format text using the toolbar — you can make words bold, add links, change font size, or insert an image. Gmail saves your changes automatically once you click the Save button, so you don't need to do anything else.

If you have multiple email addresses in Gmail (called aliases or additional accounts), you can set a different signature for each one. Look for the dropdown menu above the signature text box that shows your email address — select which account you want to edit, then set that account's signature separately.

Key Takeaways

  • Go to Settings through the gear icon, then scroll to the Signature section to find where you edit your signature text.
  • You can format your signature with bold text, links, images, and different font sizes using the toolbar in the text box.
  • If you use multiple email addresses in Gmail, you can set a different signature for each account from the same Settings page.
  • Changes save immediately when you click Save Changes, and your new signature will appear on all emails you send from that point forward.
  • You can delete your signature entirely by clearing all the text in the box and saving, which removes the signature from future emails.

Add formatting and images to your signature

The signature text box includes a formatting toolbar similar to what you see when composing an email. You can highlight text and click the bold, italic, or underline buttons. You can also change font size, text color, and alignment. If you want to add a clickable link, highlight the text you want to link, click the link icon, and paste the URL.

To insert an image — like a logo or headshot — 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 so they don't make your email slow to load or look oversized on mobile phones. Most signatures use images under 100 pixels wide.

Set different signatures for different accounts

If you manage multiple Gmail accounts or have set up aliases (additional email addresses that send from your main account), you can create a unique signature for each one. In the Signature section of Settings, look for the dropdown menu at the top that shows your email address. Click it to switch between accounts, then set the signature for that account.

This is useful if you have a work email and a personal email, or if you send from a business address and a support address. Each one can have its own signature without you having to manually edit it every time you switch accounts.

Remove or disable your signature

To remove your signature entirely, go back to Settings, find the Signature section, and delete all the text in the box. Leave it blank and click Save Changes. Your emails will no longer include a signature at the bottom.

If you want to keep your signature saved but turn it off temporarily, Gmail doesn't have a built-in toggle. Your options are to delete the text, or to compose each email and manually delete the signature before sending. Some people keep their signature text saved in a document so they can paste it back in later if needed.

Troubleshoot signature problems

If your signature isn't appearing on emails you send, first check that you saved your changes — the Save Changes button must be clicked for the signature to take effect. If you saved but still don't see it, try clearing your browser cache and refreshing Gmail, or try a different browser to rule out a display issue.

If your signature appears in some emails but not others, check whether you're using different email addresses or accounts. Each account needs its own signature set up separately. Also verify that you're not using Gmail's "Undo Send" feature, which can sometimes interfere with signature display in the preview.

If you're using Gmail on your phone, note that the mobile app doesn't let you edit signatures — you have to use the full Gmail website on a computer or tablet. The signature you set on the web version will still appear on emails sent from your phone, but you can't change it from the mobile app.

Frequently Asked Questions

Can I have different signatures for different types of emails?

Gmail doesn't have a built-in way to automatically use different signatures for different recipients or email types. You can only set one signature per email account. If you need different signatures for different purposes, you'd have to manually edit the signature before sending each email, or manage separate email accounts.

Will my signature show up on emails I forward or reply to?

Your signature appears on new emails you compose. When you reply to or forward an email, Gmail includes your signature at the bottom of your response, below the original message. You can delete it before sending if you don't want it on that particular reply.

Can I add my phone number or social media links to my signature?

Yes. You can type your phone number directly into the signature text, or use the link tool to make social media handles clickable. Just paste the URL (like your LinkedIn profile link) and Gmail will turn the text into a clickable link that opens when someone clicks it.

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

Your signature is stored separately from your password, so changing your password won't affect it. Your signature will remain exactly as you set it until you manually edit or delete it.

Can I use HTML code in my Gmail signature?

Gmail's signature editor doesn't accept raw HTML code. You have to use the formatting toolbar to style your text. If you need complex formatting, you can compose your signature in a word processor, format it there, copy it, and paste it into Gmail — Gmail will preserve some of the formatting from the paste.
