Single Opt-in is better for Solo Ads, since solo ads is mostly cold traffic - your email follw up sequence and your intial thank you page are more important.
Make sure that your thank you page is personal and you introduce yourself and tell people to expect emails from you.
Hope this helps
If you are using aweber it is not good enough to simply toggle off the double opt in. You have to contact them and insist.
Hi Glenn, when you refer to single opt-in, do you mean only requesting an email contact? If one is requesting both email and say phone contact, would this be a double opt-in?
Double optin is when the subscriber has to confirm his subscription to be added on your list by clicking a link on a confirmation email that 90-95% of times lands into spam folder and will make you lose the subscriber forever.
Thanks Maurizio for clarifying.
no a double optin means before the optin is considered a sub it must go back to its email and verify it
Thanks Glenn for clarifying. Thought I was doing something wrong by requesting both email and contact number in capture pages.
