Where to find and edit your Gmail signature

Your Gmail signature lives in Settings, not in the compose window. Open Gmail, click the gear icon in the top right, then select See all settings. Scroll down to the Signature section — you'll see it about halfway down the page. If you have multiple email addresses linked to your Gmail account, you can set a different signature for each one using the dropdown menu at the top of the Signature section.

The signature box itself is a text editor. You can type plain text, paste text from another document, or use the formatting buttons to add bold, italics, links, or images. When you're done, scroll to the bottom of the Settings page and click Save Changes. Gmail will apply your new signature to all outgoing emails from that moment forward.

Key Takeaways

  • Gmail signatures are set in Settings under the Signature section, not in the compose window.
  • You can create a different signature for each email address if you have multiple accounts linked to Gmail.
  • The signature editor lets you format text, add links, and insert images before you save.
  • Once you save, your signature appears automatically on all new emails you send.
  • Changing or removing your signature takes the same path: Settings > Signature > Save Changes.

What you can include in a Gmail signature

A signature can be as simple as your name or as detailed as your full contact information. Common elements include your name, job title, phone number, email address, website URL, and physical mailing address. You can also add a company logo or personal image by clicking the image icon in the signature editor — Gmail will let you upload from your computer, search Google Images, or paste a URL.

Keep in mind that images increase email file size, and some recipients may have images turned off by default. Text-based signatures load faster and display reliably across all devices and email clients. If you do add an image, test how it looks by sending yourself a test email and viewing it on your phone as well as your computer.

Removing or disabling your signature

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

If you want to keep your signature saved but turn it off temporarily, Gmail does not have a built-in toggle. Your options are to delete the text (and retype it later), or to create a second email address within your Gmail account with no signature and switch between them as needed. Some third-party email tools offer signature scheduling, but Gmail's native feature does not.

Why your signature might not appear on replies

Gmail's default behavior is to include your signature on new emails but not on replies or forwarded messages. This is intentional — it keeps email threads from getting cluttered with repeated signatures. If you want your signature on every email, including replies, you can change this in Settings. Look for the option Insert signature before quoted text in replies and forwards and check that box.

Even with this setting on, some email clients that receive your message may strip out or hide the signature. This is a limitation of how different email systems handle formatting, not something you can control from Gmail's side.

Signature behavior on mobile devices

Your Gmail signature works the same way on the Gmail app for iPhone and Android as it does on a computer. When you compose a new email on your phone, your signature appears automatically at the bottom. The signature you set in Settings on your computer is the one that will appear on mobile — there is no separate mobile signature setting.

If you use Gmail's web version on a mobile browser, the signature also appears as you set it. Test your signature on your phone to make sure formatting, line breaks, and any images display the way you expect them to.

Common signature formatting issues and fixes

If your signature looks different in the preview than it does in a sent email, the issue is usually how the recipient's email client renders HTML formatting. Gmail's signature editor uses basic HTML, which most email programs support, but some older or less common clients may display it differently. Stick to standard formatting — bold, italics, and links — rather than complex layouts or unusual fonts.

Line breaks sometimes disappear or shift when an email is sent. If this happens, try adding extra line breaks in the editor, or switch to plain text instead of formatted text. You can also test by sending yourself an email and checking how it looks before you send it to others. If a signature with an image is not showing up for recipients, ask them to check their email settings — they may have images disabled by default.

Using signatures with Gmail labels and filters

Your signature applies to all emails you send from your account, regardless of which label or folder you are working in. Gmail does not let you assign different signatures to different labels. If you need separate signatures for different purposes — one for work, one for personal use — the only built-in option is to create a second Gmail account and link both to your main email client.

Filters and rules do not affect your signature. A filter that marks an email as read or archives it will not change or remove the signature you already sent. Your signature is part of the outgoing email, not something that filters can modify after the fact.

Frequently Asked Questions

Can I have different signatures for different folders or projects?

Gmail does not support folder-specific signatures. If you need multiple signatures, create a second Gmail account and link both accounts to your email client. You can then switch between accounts and each will have its own signature.

Will my signature appear on emails I send from my phone?

Yes. The signature you set in Gmail Settings appears on all emails you send from the Gmail app or mobile web browser, using the same signature you configured on your computer.

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

Your signature is stored separately from your password and will not be affected by a password change. It will remain exactly as you set it.

Can I use HTML code to create a more complex signature?

Gmail's signature editor does not accept raw HTML code. Use the formatting buttons in the editor instead. If you need advanced HTML signatures, you may need to use a third-party email client or tool that supports custom HTML.

Does my signature count toward Gmail's storage limit?

No. Signatures are stored in your account settings, not in your email storage. They do not use any of your 15 GB of free Gmail storage.
