Set up your email account(s)

To set up your signature, simply go to the Settings menu:

Go to the HTML section



In your user interface, under the “Email signature” section, select and copy the “HTML code” displayed below the signature:

That’s it – your signature is now set up and will be automatically updated whenever you make future changes.



When you exit “HTML” mode, you can also add text to your signature.

All that remains is to test your signature by sending yourself an email BUT PLEASE NOTE: the link in your signature is NEVER active whilst you are editing the email; it only becomes active once the email has been received.
