Pushpages are sent out per User ID, and also to a user's Primary and CC Emails. 

Here are some reasons recipients may receive multiple emails from the same Pushpage job:
  • The same email address appears in multiple user accounts and Pushpage generates one email per recipient in the distribution group. (i.e. spouses commonly share the same email address so if both parents are in the Distribution group, they will receive the email once per parent).
  • Users appear in multiple distribution groups that the same Pushpage issue is sent to in separate job sends of the same Pushpage issue (i.e. School schedules one job with a Distribution group of 7th grade parents then a few minutes later schedules a job with a Distribution group of 8th grade parents and parent is listed in both Distribution groups). 
  • The same email address appears in both the Email and CC Email fields.
