I have an optin list in Aweber that is single optin, but here is the problem that I am having. For some of the subscribers, instead of being sent the first email in my autoresponder series, it is showing their last message as confirmation when the list is not double optin.
Can someone explain to me why this might be happening? Why are they getting sent a confirmation email or why is Aweber showing confirmation for their last message?
Do you think they are using fake email address? I have looked at many of the email address and they do not appear to be fakes.
Any help would be greatly appreciated. Thanks.
