Set a signature in Roundcube to add your contact details to messages sent through webmail.
- Open Roundcube and select Settings, then Identities.
- Select your email identity and enter your signature. Use the HTML option if you need formatting.
- Save the change, then compose a new message and send yourself a test.
If the signature does not appear, check Settings, Preferences, Composing Messages for the signature insertion option. Your phone or Outlook uses its own signature settings.
