This can happen for a number of reasons including but not limited to:
  • Interest groups that are rebuilt on send will include constituents that were were opted into the interest but not yet in the group. This is desired behavior as the purpose of an interest group is to match the interest opt-ins.
  • If an online group is mapped to an offline groups and the offline group includes constituents that are not in the online group, they may be included in the email send.
Note that if someone who is not in the Email Delivery report received the email unexpectedly, it may be that an email address in the Email Delivery report is setup to forward emails to the email address not in the Email Delivery report. There is no way for Luminate Online to be aware of this or affect this behavior in any way.
