How does Rule treat duplicates of addresses?
When member importto Rule, any duplicates are sorted automatically.
-Note that this may be a reason why your imported member's number may deviate from your total membership count before the member import.
-Please also note that members of course can be registered with different email addresses. But duplicates are sorted as said away.
-For campaigns to multiple tags as recipients, where the same address appears in both tags, the email addresses are automatically merged so that only one mailing occurs.
