Where to find your signature settings in Gmail

Your email signature lives in Gmail's Settings, not in the compose window. Open Gmail, click the gear icon in the top right corner, then select See all settings. Scroll down until you see the Signature section — it appears about halfway down the page, after the "Labels" section and before "Forwarding and POP/IMAP".

If you have multiple email accounts connected to Gmail, you'll see a dropdown at the top of Settings that lets you pick which account you're editing. Make sure you're in the right account before you make changes, because each account has its own separate signature.

Key Takeaways

  • Your signature settings are in Gmail Settings under the Signature section, not in the compose window.
  • You can create different signatures for different email accounts if you have more than one connected to Gmail.
  • Gmail lets you add formatting like bold text, links, and images to your signature, but keep it short so it doesn't overwhelm your emails.
  • Once you save your signature, it will appear automatically at the bottom of every new email you send, but not on replies unless you turn that on separately.
  • You can turn off your signature for individual emails by unchecking a box in the compose window.

Creating a new signature from scratch

In the Signature section, click the radio button next to Create new. A text box will appear where you can type whatever you want — your name, job title, phone number, website, or any combination. There's no required format; write what makes sense for your situation.

If you want to add formatting, use the toolbar above the text box. You can make text bold or italic, change the font size, add a link, or insert an image. To add a link, highlight the text you want to link, click the link icon, and paste the URL. To add an image (like a company logo), click the image icon and upload a file from your computer.

Keep your signature reasonably short. A signature that's longer than three or four lines can make your emails harder to read, especially on phones. Once you're happy with how it looks, scroll down and click Save Changes.

Editing or replacing an existing signature

If you already have a signature and want to change it, click inside the text box in the Signature section and edit the text directly. You can add or remove words, change formatting, or delete the whole thing and start over. The changes take effect as soon as you click Save Changes.

If you want to keep your old signature but create a new one alongside it, click Create new instead of editing the existing one. Gmail will let you have multiple signatures and pick which one to use for each email. This is useful if you have different roles — for example, a work signature and a personal one.

Controlling when your signature appears

By default, Gmail adds your signature only to new emails you write, not to replies or forwarded messages. If you want your signature on replies too, scroll down in the Signature section and check the box that says Insert signature before quoted text. This puts your signature above the original message, which is the standard way to do it.

Even after you set up a signature, you can turn it off for any single email. When you're composing a message, look at the bottom of the compose window. You'll see a small link or toggle that says Insert signature or shows your signature name. Click it to remove the signature from just that email.

Adding images or logos to your signature

To add an image, click the image icon in the formatting toolbar above your signature text box. You can upload a file from your computer, search Google Images, or paste a URL if you have one. Keep the image small — most signatures use images that are less than 200 pixels wide so they don't make emails slow to load or hard to read on phones.

If you're adding a company logo, ask your IT department or manager if there's a standard version you should use. Some organizations have specific rules about logo size or placement in signatures. If you're using an image just for yourself, make sure it's something professional — a photo, icon, or straightforward graphic works better than a large banner.

Troubleshooting signature problems

If your signature isn't appearing on emails, first check that you actually saved your changes. Scroll back to the Signature section and make sure there's text in the box and the radio button next to your signature is selected. Then click Save Changes at the bottom of the page.

If you're sending from a different email account than you thought, your signature might not show up because each account has its own. Check the "From" line in your compose window to make sure you're sending from the account where you set up the signature. If you need the same signature on multiple accounts, you'll have to create it separately in each one.

If your signature looks different on your phone than on your computer, that's usually because the phone is reformatting the text to fit a smaller screen. This is normal and not something you can prevent — just make sure your signature is straightforward enough to read when it's squeezed down.

Removing your signature

To delete your signature completely, go back to the Signature section in Settings and clear all the text from the box. Leave it blank, then click Save Changes. Gmail will stop adding a signature to your emails.

If you have multiple signatures and want to remove just one, click the radio button next to a different signature to make it active, or click the radio button next to No signature if you don't want any. Then click Save Changes.

Frequently Asked Questions

Can I have different signatures for different people I email?

No, Gmail doesn't let you pick a signature based on who you're emailing. You can have multiple signatures and manually choose which one to use for each email, but you can't set rules like "use signature A for work emails and signature B for personal emails." You can only have one active signature at a time, or no signature at all.

Will my signature show up on emails I send from my phone?

Yes, if you set up your signature in Gmail Settings on a computer, it will appear on emails you send from the Gmail app on your phone too. The signature is stored in your Gmail account, not on any one device, so it follows you everywhere.

Can I add a signature to emails I've already sent?

No, once an email is sent, you can't add a signature to it. Signatures only appear on new emails you compose after you set them up. If you need to add a signature to an old email, you'll have to forward it or resend it as a new message.

What if my signature has a link but it's not clickable?

Make sure you used the link tool in the formatting toolbar, not just typed the URL as text. Highlight the text you want to be clickable, click the link icon, and paste the full URL including "https://" at the start. If the link still isn't working, check that the URL is correct by clicking it yourself before you send.

Can I use HTML code to make my signature fancier?

Gmail's signature editor doesn't support raw HTML code. You're limited to the formatting options in the toolbar — bold, italic, font size, links, and images. If you need something more complex, you might need to use a third-party tool or ask your IT department if your organization has a signature template system.
