Do you use single opt-in or double opt-in ?
Any reason that you are using single/double opt-in ?
I recently encounter this problem when using single opt-in
After i subscribe to my own list, the message cannot be deliver immediately,
the worst part is that it does not deliver to my hotmail account.
The only success message is to my Gmail account, but this happen after more than 12 hours.
Anyone know how to fix this problem?
I'm using GetResponder
