including a Link in an SMTPsocket email

I’m creating and sending an email message. I want to include a hyperlink in such a way that the identity of the link (Unsubscribe) appears in the email, but the destination of the link (http://www.mysite.info/unsubscribe?XX=somestuff) does not appear until the link becomes activated, e.g. by a mouse hovering over it. Is this possible?

Solved by sending the msg. as HTML. Thanks, Michel.
