To use HTML formatting in your signature, check Use HTML and format the Signature text with the desired HTML mark-up. Plain text signatures work with messages formatted both in HTML and in text. To configure a plain-text signature, enter the text you want to append to each outgoing message in the Signature text field. If you have multiple email accounts, you must configure signatures separately for each account. Click Tools Edit > Account Settings, and then, in the left panel, select the account for which you want to create a signature.
