In my opinion, Aweber is The Best email autoresponder on the market today. As someone who is a HUGE FAN of Aweber, I find it sad that you left them without calling customers support OR MYSELF, JUPITER JIM, (on skype, of course) to help walk you through things. It is so easy, breezy when they just walk you through everything step-by-step over the phone.
Back to my using AWeber to build a loyal following…in December I was asked by the New York Times to contribute a mini op-ed. I think I almost doubled my subscribers because I already had the system in place to capture those subscribers when they visited my website from the NYT page. Not that I have a huge number of subscribers yet, but I am getting there in part because of using a professional system.
Pam, we are sure JetPack has nice features and all but it allows you to add a blog / comment subscription module only. On the other hand services like MailChimp and Aweber are professional email service providers offering many powerful features which allow you to really benefit from the email list you are building. As far as simplicity is concerned, we are slightly more inclined towards MailChimp, they have a great user interface even for absolute beginners, they have excellent documentation, and lots of resources to learn how to use each feature available.
Before you can send AWesome emails with AWeber, you'll need someone to send it to. The easiest way to begin building your list is to import contacts that have opted-in to your email list, or gave you permission to send them emails. These could be subscribers you've emailed from another provider, or a list of contacts that you've built through your business.
