I would like to know what did you do with unconfirmed subscriber list ? (For double-opt in)
There are only few reason I can think of why they are at that "Unconfirmed" list category..
1) They simply do not want to be subscribe to your list
2) They did not receive the confirmation email after singing up
3) The confirmation email went to junk box
Either way... What will you do with these email list?
I'm using Get-response and I'm thinking of either change my optin into single opt-in method or upload the list 90 days later directly into my existing list....
What do you think?
