About 55% of the people on my email list have the "Confirmation Pending" status. I've read the average for double opt-in is about 30-40% so I seem high. Once they subscribe, they are directed to a page that says "Check your spam folder". I've customized my welcome title to say "MY SITE NAME - Please confirm you subscription". I had my girlfriend test out my email opt-in and the confirmation email went straight to spam.
I'm reluctant to go to single opt-in because I want to know that my subscribers want to be there and are real but this seems a little ridiculous. Any ideas?
