There are drawbacks, however, and they are threefold: first, the program seems to be falling behind on the social media front. Second, AWeber is a little on the pricey side, especially for businesses with very small lists (1000 and under). Once you hit the 2500-subscriber mark, costs are more in line with industry averages. The company has no send-based subscription plan, which means if you have a large list but send infrequent emails, there are probably better choices for you. Third, the company makes its free trial unnecessarily burdensome by requiring a credit card. This would be a minor issue if not for the fact that customers have reported complications with canceling the service.
Very nice comparison of Mailchimp and Aweber. It looks like both Aweber and Mailchimp will suspend you without notice for seemingly trivial reasons. I think it is always good to have a backup system of your own. I use autoresponderplus and 12all scripts and have backups of my campaigns. Aweber is a great service you just never no when you might offend them. It seems like Mailchimp is even touchier. I think the best solution is not to rely completely on any one service. Nice post!
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.
