I have a double opt in email list on the 4 websites and 2 blogs that I have. I don’t have one on the other websites that are optimized only for Adsense since I will not be trying to sell them anything and usually email marketing doesn’t work that well with pay per click optimization sites.

But with blogs, I think that a double opt in email list is pretty important if you have enough traffic right now to justify using one. If you have only a couple hundred visitors a month on your blog, then I would not waste my money at that point on the autoresponder program. But if you have a couple hundred unique views a day on your blog, then it may be worthwhile. You can always test it out and see if you are making up the difference for the program in the extra money you see.

Another added plus that I learned was that if you have a double opt in email list you will not have to worry about spam bots joining your email list. These bots can’t confirm the email so they never get put on the list. If you want to learn more info on email list, then I recommend you check out.
