Coy, as someone who lives (now) in Atlanta because I met my spouse on an Atlanta dating site (7 yrs. this Sept.!), I might suggest some articles from success stories either from your site or articles on internet dating in general. People come to these sites not only to find others but to understand and be motivated by the process and the service.
Offer tips and have them optin for something like a free guide to hot spots around ATL or tips on meetup situations. Seek out MeetUp groups for not only dating but individual interests groups. Check out the Atlanta Wine Club and see if they will let you sponsor a singles wine tasting or hook up with an upscale wine store for the same (I have one opening up next month right in front of my store.)
By offering interaction with the visitor who leaves an email address, you have a list to do email promotions for.
Good luck and let us know how you are doing.
And if anyone gets married, my store is dedicated to brides and babies :-)
