One of the final clinchers in the decision to move to Aweber was when I found out that you can completely integrate your Feedburner emails as well as have your new Aweber email subscribers count towards your Feedcount. For those of you out there who like to display the number of readers your blog has you can rest assured knowing that all your new subs will be included in that count.
One of the best features of AWeber is the ability to create a series of emails that are automatically sent out to new subscribers. This allows you to create an eCourse or some sort of introductory guide for your latest subscribers. This is fantastic as you can market it as an incentive for people to subscribe (e.g. subscribe and get our free 7 day eCourse) and once setup, you can leave it to be sent out automatically.
