The usability of most of the site is actually not bad; I even like the design look and feel. However, the signup process is where I had (and am still having) trouble with. Just simply getting a reply from them on anything takes hours and hours, but when you look search usability and mailchimp.com, they are all kinds of busy writing blogs about their mobile usability testing and how great they are. So they are so focused on their mobile they forgot that the #1 focus should be getting new users fast, and keeping them with good support… what a JOKE! Mailchimp.com is usability and customer support FAIL!
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.
