If you are looking for an email management software and you want your emails to get through SPAM filters, Aweber is one of the best choice you can make. Aweber has the strongest relationships with most hosts including Yahoo, Gmail and MSN and hotmail. You have the highest chance of deliver-ability with it and avoid your messages from going into your client’s SPAM folder.
Another Email Manager Autoresponder solution that I use is 1AutomationWiz. This integrates shopping cart and autoresponder. Just connect it with your Merchant Account. 1Shopping Cart is the 1 shopping cart system that the top marketers out there are using .
There are also free alternatives to check into.
For example MailChimp has both a free and paid option.
