I am currently using Campaign Monitor for an ESP for email blasts but I'm not wild about it. My primary issue is that I maintain multiple lists from various campaigns. It's becoming increasingly difficult to consolidate these lists when I send out email blasts and even further difficult when I have to do a resend. For example lets says i have 20 email lists, i can check them all off and send but when I have to resend to those who haven't opened I have to go to each and every list and create a condition, very annoying.
Are there any suggestions for ESPs that can simplify this workflow for resends by consolidating the misc lists etc?
