I am impressed by how responsive you are. Thanks
In terms of rule based sending, I wouild like to use ListMail to send out eBirthday cards to patients. This means having a rule element that is able to evaluate dates. ie, is today's day and month equal to day and month in birthday date field, if yes, send. If you can do this, I would bet dentists would make good use of ListMail since the do all types of date driven stuff.
One bit more on clarification of duplicate screening on import. Does ListMail filter out duplicates relative to the list being inported into, or the whole data base. If it is screening with regart to the specific list, what happens when you move a record from one list to another and this produces a duplicate for that list. What would be nice to happen is that you would have an option to merge the two records to that any empty fields in one would be filled in by the other record, setting one list as the priority list.
Thanks
