Generally pretty good service. Messages are received very quickly. Something to improve: 1. Need a better User Interface throughout the site - current interface is so out dated 2. Need better Import functionalities, accept more than just name and phone number columns, e.g. Group? 3. Better Reporting, say easier to view sent messages by transaction? 4. Automatic Opt-Out processing: should notify user that someone opt-out. Say, place the number if an "Opt-out" group? 5. Contact view: 5.1 Only show modification interface when user want to edit, otherwise, just show read-friendly interface. 5.2 Add search criteria - filtered by group, name, number, etc 6. Keep the same low rate for ongoing purchases - people could simply register another account to by pass the rule. Good luck and keep on moving forward.
