Your signature is also available on the mobile. Here are the steps how to use your desktop signature on the mobile:
- Go to the Gmail app on your iPhone (Gmail app on Android still does not support desktop or HTML signatures)
- Make sure you have the Mobile Signature option unchecked in your settings. Having this on will override the Desktop Signature. So make sure it is off.
- Now, just send an email to yourself. You’ll see the signature in the email you receive from yourself.
