We're in the process of adding an "invite your friends" feature to our dating site, and I was wondering if anybody has any tips/past experience in the best way to utilize the invites. Here's what I have so far :
1 - Will be CAN-SPAM compliant
2 - Allow users to select from their addressbook which contacts to invite to
3 - Have a compelling message / call to action in the email : "John thinks you should try out sitesite.com, where is is looking for his soulmate"
4 - If no action from the user for a week, send another invitation "Invitation reminder, you're missing out on meeting thousands of singles at sitesite.com"
5 - Is it better to have a html-heavy invite (hi5,zoosk, msn messenger) or more text-based (facebook, gmail, ghcat) ?
Anything I'm missing to help convert these invites into members ?
