Currently, you can use an HTML signature in the Gmail web app google.com/gmail (for more details, please check our guide Can I use my signature on Android?) or only a plain text signature in the Gmail app on Android.
Please follow these steps on how to create a plain text signature and use it in your emails composed in the Gmail app on your phone on Android:
Step 1. Create a plain text signature.
To create a plain text signature, you can create a new signature from scratch by clicking New signature button (here is our detailed guide) or duplicate any of your signatures (here is our detailed guide).
Note: Plain text signatures are limited to text-only content and do not support images or hyperlinks. We recommend you include only User Info and Contact Info in this signature version.
For example, this is how a plain text signature can look:
Step 2. Install your signature.
2.1. After you have created and saved your signatures, open the signature preview link on your phone on Android, then tap on Copy to clipboard button or scan a QR code.
2.2. Open the Gmail app by typing its icon on your Android phone.
2.3. Select your mail account.
2.4. Then go to the Main Menu.
2.5. Open Settings.
2.6. Choose for which your mail account you would like to add your signature.
2.7. Scroll down to the Mobile signature settings.
2.8. Paste your signature into the settings, edit its design, and click OK.
Note: Make sure you don't have any transparent images in your signature (if you see any, select and remove them), then click OK to save all changes.
Nice work! Now, each email you send from your Gmail app on your Android phone will include your plain text signature.
