Like a fair number of marketeers, I use both single and double opt-in thru Aweber; I also have a second autoresponder that demands the use of double opt-in.

Since I'm still learning from the consequences of using each, and when single opt-in is most appropriate, I really appreciate your post and the links with it and the replies.

Double opt-in certainly weeds-out the window-lookers, but sometimes that is all I want, and I always keep questioning, way in the back of my mind, whether my opt-in email ended up in the spam bucket and was never even seen. All of the pre-filtering hints that my emails are not regarded as spam, but with a verify/confirmation rate of only 1 in 3, I really question the validity of the pre-filter.

I know my mindset is not that of the average Joe, but to opt-in and not confirm seems the result of only one thing provided the email is opened... poor copy for the opt-in email. But even with that aside, I know when I opt-in, I try to overlook the content and grammer of the resulting email because I intend to confirm and get that 1st "true" email. But then, I'm not one of those individuals who has ill intent or other motives in filling in a sign-up form.

But I ramble... thanks for the post!
