Great article comparison and review! Man I wished I had read this before getting in bed with mailchimp.com – You are correct they have the WORST customer service there is… I have been waiting for more than 24 hours now for a resolution as to why they suspend my account – turns out I didnt answer some questions in a lengthy email they send out. I could not call them because they do not have a phone number.

MailChimp always tempts me in terms of design and looks, and more over they keep adding new features, which will be helpful in your Email marketing campaign. The Best thing about MailChimp is, it’s free for first 2000 subscribers, and you will not be charged anything until you have crossed their free limit. This is useful for bloggers, who are worried about moving from Feedburner to another paid Email marketing services, as with free you have nothing to lose.
With a newly redesigned email editor, which makes it easy to pick back up on draft messages right where you left off or turn them into drip messages, AWeber is an email marketing app that does it all. If you need a professional email tool that’ll help you grow your lists and offer live phone support if you get stuck, it's a great email app to try. - Matthew Guay
I’m not sure but as far as I can remember (or at least about 2 years ago) I found a function to activate the subscribers without their needing to opt-in (even though a warning from Aweber would pop up). I lost about 70% of my subscribers in my very small list back then when I changed, but I’ve been able to grow it ten-fold since. And I used opt-in, because I didn’t want anyone to complain to me later.
If I didn’t post for a while, and then sent something out, I’d get a handful of unsubscribes from people who basically forgot they were on my list. This method wasn’t ideal for building the know, like and trust factor. Yes, of course, I would say that I should be working on consistency (and I am — which is why I hired a Content Director!), but until I have that locked down, I wanted a different way to give people a solid, valuable user experience when they first join my list.
Now, you can automatically send highly relevant emails encouraging them to buy the product or service they were considering. Customers who received multiple abandoned shopping cart emails are 2.4 times more likely to complete the purchase than those who receive only one followup email, according to Experian. Try sending the first message one day after, a second message 48 hours after, and possibly a third message within three or four days of abandonment.
