High retention is the way to high income.  We have been using this system for years for primarily two categories of members:  New Members and Members in Pre-Cancel.  Just enter their names and email addresses, choose the category they should be in, and the system starts sending them the appropriate emails.  Of course we also call our members, but sometimes we cannot reach them, so the emails help fill in the gap & validate our conversations when we do reach them.  It’s well worth the monthly cost.
