If you want to integrate with PayPal and Amazon – AWeber wins. I prefer AWeber to MailChimp, but that’s only because it lets me integrate with Google Analytics. Also, if you have affiliate marketing links on your site, MailChimp will cancel your account without notice! Nobody knows why, and MailChimp says they will assess it, but it still happens with no warning!
The main weakness I see is the price-point where small companies are concerned. If you don’t need all of AWeber’s bells and whistles, there’s no reason to pay for them. You’ll also want to make certain that if you are trying to cancel your account, you’re not just accidentally suspending it. This is especially important where the free trial is concerned, as AWeber requires your credit card info.
You see, the people on your email list are your best customers. They have visited your site and found it interesting enough to subscribe for more content. For that reason alone, they are much more likely to listen to any offers you may send them (affiliate promotions, product sales, discount coupons, etc.). So, having a large email list can actually be quite profitable, which is why bloggers and website owners hold them in such high regard.
After you have entered your "List Name" you will need to enter a "List Description." Here is where you will describe the kind of information you'll be sending from this list. There is a 400 character limit for the "List Description." Subscribers will see your "List Description" on the unsubscribe page if they ever go to unsubscribe from your list. Once you are done entering your "List Description" click the "Next Step" button.
