Gmail App on Android
The Gmail app on Android only supports plain text signatures set through the app. For HTML signatures, set them via Gmail web:
- Open Gmail.com in Chrome on your Android phone (or computer)
- Tap the gear icon → See all settings
- Scroll to the Signature section on the General tab
- Create a new signature and paste your HTML code
- Choose defaults for new emails and replies
- Save changes
⚠️ Important: Gmail web signatures only appear when sending from the Gmail web interface. The Gmail Android app has its own plain-text-only "Mobile signature" setting (hamburger menu → Settings → [account] → Mobile Signature).
