To create a link that allows to you to forward to a friend use the tag %PERS_FRIEND%. This directs you to a page that asks your name, friend’s email, friend’s name, and a personalized message. After filling out the form the friend receives a “thought you may be interested in this mailing” letter with a link on the bottom. To create a clickable link that will forward the mailing to a friend you can use the format
<a href=”%PERS_FRIEND%”>Click here to forward to a friend</a>
