What a Gmail signature is and why you might want one

A signature in Gmail is a block of text that appears automatically at the bottom of every email you send. It usually contains your name, job title, phone number, or a short message — anything you want readers to see without typing it each time.

Gmail lets you create one signature that goes on all your emails, or different signatures for different email accounts if you manage more than one through Gmail. You can also turn your signature off for individual emails if you need to.

The signature lives in your Gmail settings, not in the email itself, so you can change it once and it updates on every message you send going forward.

Key Takeaways

  • You create and edit your signature in Gmail Settings under the "General" tab, in a section labeled "Signature".
  • Your signature can include text, links, images, and formatting like bold or italics, but keep it short — most people read it in a glance.
  • If you manage multiple email addresses in Gmail, you can set a different signature for each one.
  • You can disable your signature on a single email by unchecking the signature box that appears in the compose window before you send.

How to open Gmail Settings and find the Signature section

Start by opening Gmail in your web browser and signing into your account. In the top right corner, you will see a gear icon. Click it and select "See all settings" from the menu that appears.

You are now in Gmail Settings. Look for the tabs at the top of the page — you should see "General", "Labels", "Inbox", and others. Click the "General" tab. Scroll down the page until you see a section titled "Signature". This is where you write and format your signature.

Writing and formatting your signature text

Click inside the text box under "Signature" and type what you want to appear at the bottom of your emails. A typical signature might read: "Jane Smith | Marketing Manager | (555) 123-4567 | jane.smith@company.com".

Gmail's signature editor lets you make text bold, italic, or underlined using the toolbar above the text box. You can also change the font, text size, and text color. Use these tools sparingly — a signature that is too colorful or large can look unprofessional and may not display the same way on every device.

You can add a line break by pressing Enter, which helps separate your name from your contact details. You can also paste a link into your signature — highlight the text you want to link, click the link icon in the toolbar, and paste the web address.

Adding an image to your signature

To add a logo or image to your signature, click the image icon in the toolbar (it looks like a small picture frame). A menu will appear with options to upload an image from your computer, search the web, or paste an image URL.

Keep images small — a logo should be no more than 100 pixels wide so it does not make your signature take up half the screen. If you upload an image from your computer, Gmail stores it on your Google Drive, so the image will stay in your signature even if you delete the original file.

Setting different signatures for multiple email accounts

If you manage more than one email address through Gmail (for example, a work account and a personal account), you can create a separate signature for each one. At the top of the Signature section, you will see a dropdown menu that says "— No account —" or shows your current email address.

Click that dropdown and select the first email address you want to set a signature for. Write or paste that signature in the text box. Then click the dropdown again, select the next email address, and create a different signature for it. Each signature will appear only when you send from that account.

Turning your signature off for a single email

Once you have created a signature, it appears on every email you send by default. If you need to send one email without your signature, open a new email to compose. At the bottom of the compose window, you will see a small checkbox next to your signature text. Uncheck that box, and your signature will not appear on that email.

The signature stays in your settings — you are only removing it from this one message. The next email you send will have your signature again.

Saving your changes

After you finish writing and formatting your signature, scroll to the bottom of the Settings page and click the "Save Changes" button. Gmail will confirm that your settings have been saved.

Your signature is now active. The next time you compose a new email, your signature will appear automatically at the bottom. If you do not see it, refresh your browser or sign out and back into Gmail.

Frequently Asked Questions

Can I use HTML code in my Gmail signature?

Yes. In the Signature section, click the three dots menu icon and select "Plain text" to toggle it off. This lets you paste HTML code directly. Be careful — broken code can make your signature look strange or not appear at all. Test it by sending a few emails to yourself first.

What happens to my signature if I delete my Gmail account?

Your signature is stored in your Gmail account settings. If you delete your account, the signature is deleted too. If you want to keep a copy, copy and paste your signature text into a document before you close your account.

Can I schedule my signature to change on a certain date?

Gmail does not have a built-in feature to schedule signature changes. You would need to manually edit your signature in Settings whenever you want to update it. Some third-party email tools offer this feature, but they require extra setup.

Why is my signature not showing up on emails I send?

Check that you saved your changes after creating your signature — many people forget to click "Save Changes" at the bottom of Settings. Also check that the signature is not turned off for that specific email (look for the checkbox in the compose window). If you just created the signature, try refreshing your browser.

Can I add a signature to emails I receive?

No. A signature only appears on emails you send. It is added by your account, not by the person who wrote the message. If you want to reply with a signature, compose a new email instead of using the reply button.
