Or, does??send only one copy of the message to the recipient? ? For example,?john@...?is a member of three different subgroups. ? If a message is sent to all three subgroups, does John receive three versions of the same email (or does the system eliminate all but one message)? ? The use case I am inquiring about includes the same email address within multiple subgroups (not different email addresses for same recipient). ? If the answer is ¡°no¡±, then is there a setting that enables receipt of only one copy of the message??
