Hey, Firstly I'm not sure if this is the right section to ask this doubt, il just give it a go..
So I ran this Facebook campaign which was collecting the user's name and email and was forwarding them to one of the dating site I have in file..and the users would then sign up to the respective dating site..
Now this number has grown large and reached 15,000 over a course of time..I'm not sure of how can it be monitized..due to the same fear, I haven't sent them a single email..
If you had any past experience or an idea that you think could work..can you please share it with me?? even a small idea or experience is appreciated, Thanx Guys..

outside of promoting other general dating sites:
- Men: Cougar Dating sites or Cougar Dating LPs to good converting offers (Sugarmomma angle works too) || Women: sugardaddy offers or Sugar Daddy LPs to converting general offers... or Run cougar dating offers for older single women
- Men: How to pick up women (and the billions of sub niche offers in this niche) || Women: get a quality guy/get your ex back/etc offers
- Men: Male muscle offers/diet offers/workout programs/truth about abs/fatburningfurnace || Women: truth about abs/fbf/diet offers/skin offers
Outside of those, bizop offers targetted to men saying shit like "women love successful men/etc"
Get creative man... just get some angles going and the conversions will flow.
How about if you can jump out of dating offers in email as the users must have already joined a lot of other dating websites...???
Not sure but I wanted to see what stackers have got for this. I am curious as well.
Millions of fresh (virgin) dating data available if anyone wants to buy, PM/Skype me.
If anyone is able to mail the data for me and wants to make some money, contact me too 
The "halflife" or "decay" on a collected email is very short. Ie if you capture the email and dont write to them within the first few days, your open and click through rates will drop drastically.
I suggest you:
1) spy - sign up to some of the top dating email lists that target your same demo - ie http://www.doubleyourdating.com/
2) survey - take a 1000 random sample of your list and mail them a survey to find out what your dealing with
3) build your AR sequence mixing value with offer - ie V V V O V V O V V O V O O O
I'd promote offers to them based on demographics, don't just promote dating style offers to them. If you get, for example, males ages 18-24 market deals that are tailored to them additionally to dating offers. You can also API the emails into a couple merchants if you have the conncetions.
how long has it been since you collected their emails / haven't mailed them. Depending on how long it has been, you may need to structure your headline / copy to even get them to open at this point.
As far as offers go, if it's males, try adult (if your mailing client will accept it), or just more dating like someone already mentioned, or muscle / get ripped, or one of those how to pick up girls ebooks. Might want to start your initial reachout to them without including any offers and try to rekindle whatever potential there is left in your list.
