How to add an HTML email signature in Gmail
Gmail lets you paste a formatted signature straight into its settings. Here is how to do it, and how to fix the usual problems.
Add your signature
- Build your signature in the signature generator and click Copy signature.
- In Gmail, click the gear icon, then See all settings.
- On the General tab, scroll down to Signature and click Create new. Give it a name.
- Click in the signature box and paste with Ctrl+V (Windows) or Cmd+V (Mac).
- Under Signature defaults, choose when it is used: for new emails, and for replies and forwards.
- Scroll to the bottom and click Save changes.
Get the best result
- Host your images online. Gmail shows images from a public web address, not from your computer.
- Tick "Insert this signature before quoted text in replies" if you want it above the conversation history.
- Keep it short. Four to six lines is plenty.
- Send yourself a test email and look at it on your phone as well.
Troubleshooting
If images appear broken, they are not hosted at a public address. Upload them to your website or hosting and use that address in the signature.
If fonts look different, Gmail only supports a limited set of fonts. Use a standard one such as Arial or Georgia.
If the signature does not appear on new emails, check the Signature defaults setting on the same screen.
