On Android, the Gmail app uses a plain text mobile signature, while the Outlook app keeps a slightly richer one. For a fully formatted signature with an image, set it in Gmail on the web and send from a computer when it matters. Here is how to handle each app.
In the Gmail app
- Open the Gmail app and tap the menu (three lines), then Settings.
- Tap the account you want.
- Tap Mobile Signature and type the text you want.
- Tap OK. Gmail adds this to messages you send from the phone, as plain text.
Because this is text only, keep it short: name, role and one contact line.
In the Outlook app
- Open the Outlook app and tap your profile, then the gear for Settings.
- Tap Signature.
- Type or paste your signature. Outlook on Android holds more formatting than Gmail, though complex layouts still simplify.
Getting a formatted signature
For a signature with a hosted image and styled links, the dependable approach is to build it in the signature generator and paste it into Gmail on the web following the Gmail guide. That signature rides along on mail you send from a computer. On the phone itself, plain text is the practical limit for Gmail.
A note on images
Even where an app accepts an image, the picture must be hosted at a public web address to load for recipients. Host your photo or logo publicly and use that link in the generator.
