The Gmail app on Android doesn’t have an HTML signature field. The good news: it will use the signature from your web Gmail account automatically. There’s also a manual workaround if you need a device-specific signature.
Option A — Use your web signature (easiest)
- Set up your signature in web Gmail on desktop.
- As long as you haven’t set a mobile-specific signature in the app, the Android Gmail app will automatically use your web signature on sent mail.
Option B — Manual workaround
- Add your signature to web Gmail, then email yourself a message so it includes the signature.
- On your Android phone, open gmail.com in Chrome, open that email, and press-and-hold to select all of the signature, then Copy.
- In the Gmail app go to Settings → your account → Signature settings, clear any old text, press and hold to Paste, then Save.
