How do I add an email signature / alias in Webmail?

Open Webmail in your Solve account > click Settings > Sending > Email identities > Add an email identity. Then add your name, email address, and signature.

The top email identity listed acts as the default email address when sending messages. Other email identities can be selected from a drop-down list in the “From:” field. Create as many email identities as you need, and edit existing identities freely.
