Here’s how to change your email signature in Gmail, plus a few extra tips so it actually looks good and professional.

How to Change Email Signature in Gmail

On a computer (browser)

  1. Open Gmail and sign in.
  2. Click the gear icon in the top-right corner (Settings).
  3. Click “See all settings”.
  4. In the General tab, scroll down to the Signature section.
  5. Click the signature you want to edit (or Create new to make a fresh one).
  6. Use the editor box to:
    • Change your name, title, and contact info
    • Adjust fonts, colors, and alignment
    • Add links (website, LinkedIn, etc.)
    • Insert an image or logo
  7. Under Signature defaults , choose:
    • Which signature to use for new emails
    • Which signature to use for replies/forwards
  8. Scroll to the bottom and click Save changes.

Now compose a new email and check that your updated signature appears.

On Gmail mobile app

Android

  1. Open the Gmail app.
  2. Tap the three horizontal lines (menu) in the top-left.
  3. Tap Settings.
  4. Choose the account you want to edit.
  5. Tap Mobile Signature or Signature settings (wording can vary slightly by version).
  6. Enter or change your signature text.
  7. Tap OK or Save.

Note: The mobile signature is usually plain text and separate from your desktop signature.

iOS (iPhone/iPad)

  1. Open the Gmail app.
  2. Tap the three horizontal lines (menu).
  3. Tap Settings.
  4. Choose your email account.
  5. Turn on Mobile Signature (if it’s off).
  6. Type your new signature.
  7. Tap Back to save and exit.

Again, this is usually a simple text signature, not as fancy as the desktop version.

Quick example signature (you can copy the structure)

You can paste something like this into the signature editor and customize:

Jane Doe
Marketing Manager | Acme Corp
+1 (555) 123‑4567 · [email protected]
www.acme.com

Keep it short , readable, and not full of quotes or long disclaimers unless your company requires them.

Styling tips so it looks modern

  • Keep it to 3–6 lines; shorter is more professional.
  • Use one main font (e.g., Arial, Sans Serif) and 1–2 colors at most.
  • Add your website and one or two key links (e.g., LinkedIn, portfolio).
  • If you use a logo or headshot, make it small so it doesn’t dominate the email.
  • Send yourself a test email to see how it looks on both desktop and phone.

Mini FAQ

  • Can I have multiple signatures?
    Yes, in Gmail settings you can create several signatures and pick different defaults for new messages vs replies, or switch signatures from the compose window.

  • Why doesn’t my signature show on replies?
    Check Signature defaults in Settings and make sure a signature is chosen for “On reply/forward.”
