Hey, I just started a contest where all you need is an email and name to join. This contest is for dog owners, and the prize is a dog item. I did this because I have a website with 30k unique hits per month and I wanted to start getting emails, but I am wondering how much should I spend to acquire each 1 email. As in, ATM my prize is a $10 item, how many emails should I be happy with when i give that out. Thanks.
