In our organization there can be multiple contacts representing the same person at different accounts, meaning their contact primary email may or may not be the same email address. We are interested in implementing the marketing module but have a couple questions we cannot answer from looking over Microsoft's marketing module documentation.
1. In the situation that 2 contacts have the same primary email address and are part of the same segment that we send an email to, does the marketing module only send the marketing email once or will it send it twice? From this page it sounds like only 1 email will be sent: docs.microsoft.com/.../mkt-settings-default-marketing
2. Based on the scenario in question 1 how are the insights tracked in this scenario? will the insights on how the contact interactions (clicks/open/bounce) with the contact email roll up to both contacts?
