Okay so, I've been running giveaway type contests for quite some time now. Honestly I don't do these to build up a list but really just to get some exposure to new sites.
I have a bunch of lists, some are pretty dated, over a year old.
The problem I'm having is that I can't really make jack from them after the giveaway ends. Mailing offers in the niche that matches the site doesn't really seem to work on the contest lists. It seems like about 95% of the list just signs up for a chance at the prize and the open rate is awful. Mailing the list about updates to the site sends some traffic so I keep at it.
Trying to keep them engaged with a loop doesn't seem to work, I feel like I'm trying to keep the attention of a bunch of rocks.
I'm at the point where I'm thinking about just deleting the lists entirely.
Optionally I could start mailing free CPA offers. I'm just trying to figure out what to do with these lists here. Please don't respond with something like "Sell them to me" or "Sell Solos."
