Add a signature in Gmail settings in under two minutes

A Gmail signature is a block of text that appears at the bottom of every email you send — typically your name, job title, phone number, or a company tagline. You add it once in Gmail settings, and it attaches automatically to all outgoing messages. The process takes about 90 seconds and requires no special tools or permissions.

Open Gmail in your browser, click the gear icon in the top right, select "See all settings", then click the "Signatures" tab. Type or paste your signature text into the box, click "Save Changes" at the bottom, and you're done. The signature will appear on every new email and reply you send from that account.

Key Takeaways

  • Signatures are stored in Gmail settings and explore to all emails you send from that account automatically.
  • You can create different signatures for different email addresses if you manage multiple accounts in Gmail.
  • Signatures appear in plain text by default, but you can add links, line breaks, and basic formatting using HTML.
  • Mobile Gmail does not show the signature editor, so you must add or edit signatures on a computer or through the Gmail website.
  • A signature does not affect email security — it is straightforward text that displays at the end of your message.

Step-by-step: creating your first signature

Log into Gmail and look for the gear icon in the top right corner of the page. Click it and select "See all settings" from the dropdown menu. You will land on the Settings page. Click the "Signatures" tab — it is the fourth tab from the left, after "General", "Labels", and "Inbox".

In the Signatures section, you will see a text box labeled "Create new". Click inside it and type or paste your signature. Keep it short — a name, title, and phone number is standard. Press Tab or click outside the box to save what you typed. At the bottom of the page, click "Save Changes" in blue. Gmail will confirm the save with a message at the top of the page.

Your signature now appears on every new email you compose. If you reply to an existing email, the signature appears below your reply text. You can edit or delete your signature anytime by returning to Settings > Signatures and clicking the text you want to change.

Using different signatures for different email addresses

If you manage multiple Gmail accounts from one browser — for example, a personal account and a work account — you can create a separate signature for each one. Gmail stores signatures per account, not per browser, so each address has its own signature settings.

Switch to the email address you want to add a signature for (use the profile icon in the top right to switch accounts), then go to Settings > Signatures and create a new signature for that account. When you compose an email from that address, only that signature will appear. This is useful if you want a formal signature on work emails and a casual one on personal emails.

Adding formatting and links to your signature

By default, Gmail signatures are plain text. If you want to add bold text, italics, a line break, or a clickable link, you have two options: use the formatting toolbar in the signature box, or write straightforward HTML code.

The formatting toolbar appears above the signature text box. Highlight the text you want to format, then click Bold, Italic, Underline, or other options. For a clickable link, highlight the text, click the link icon, and paste the URL. Gmail will convert it to a working link in your emails.

If you prefer to write HTML directly, you can paste code like <a href="https://example.com">Visit our website</a> into the signature box, and Gmail will render it as a link. However, most people find the toolbar simpler and faster.

What happens to your signature when you reply or forward

When you reply to an email, your signature appears below your reply text, separated by a line. The original message stays below your signature. When you forward an email, your signature appears at the bottom of the forwarded message. In both cases, the recipient sees your full signature just as they would on a new email.

If you do not want a signature on a particular reply or forward, you can delete it before sending. Highlight the signature text and press Delete, then send the email. The signature will still appear on your next email — removing it from one message does not change your settings.

Signature size and best practices

Keep your signature under five lines. A long signature makes every email harder to read and can trigger spam filters if it contains too many links or looks like advertising. A standard signature includes your name, title, phone number, and company name or website.

Avoid using images, logos, or special characters in your signature unless you are certain the recipient's email client can display them. Some email programs strip out images or render special characters as question marks. Plain text with one or two links is the safest choice for signatures that work everywhere.

Removing or changing your signature

To delete your signature entirely, go to Settings > Signatures, click inside the signature text box, select all the text (Ctrl+A on Windows, Command+A on Mac), and press Delete. Click "Save Changes" at the bottom. Your emails will no longer include a signature.

To change your signature, open Settings > Signatures, click inside the text box, edit the text, and click "Save Changes". The new signature will appear on all emails you send from that point forward. Old emails you already sent keep their original signature — changing your settings does not alter past messages.

Frequently Asked Questions

Can I have more than one signature in Gmail?

Yes. In Settings > Signatures, you can create multiple signatures and choose which one to use when you compose each email. Click the dropdown menu above the signature box to select which signature appears on a new message. This is useful if you send different types of emails — for example, a formal signature for client work and a casual one for internal team messages.

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

The Gmail app on iPhone and Android does not have a signature editor, so you cannot add or edit signatures from your phone. However, if you created a signature on a computer, it will appear on emails you send from the Gmail app. To change your signature, you must use Gmail in a web browser on a computer.

Can I add an image or logo to my signature?

Gmail's signature editor does not have a built-in image upload tool. You can paste an image URL into an HTML link, but many email clients block images by default, so recipients may not see it. For a logo or image, it is more reliable to add it to your email message manually rather than in the signature.

What if my signature does not appear on emails I send?

Check that you clicked "Save Changes" at the bottom of the Settings page — the signature text box alone does not save your changes. Also verify you are in the correct tab (Signatures, not another settings tab). If you use multiple email addresses, make sure you created the signature for the account you are sending from, not a different account.

Does adding a signature affect my email security?

No. A signature is straightforward text that displays at the end of your message. It does not change how Gmail encrypts your email, does not weaken your password, and does not make your account more vulnerable to hackers. It is purely a formatting feature.
