Dear community, I'd appreciate hearing about your experience with a challenge I'm facing in Dynamics CRM (Customer Insights - Journey).

In CRM, we have contacts that interact with our company from different roles: partners, alumni, donors, event attendees, newsletter subscribers, etc.

They also have different emails for different roles: corporate emails, private emails, etc.

So, in the end, we end up with duplicates, which I can merge, of course, but it raises the following questions:

• What happens with their consent/subscriptions?
• How do I distinguish, in segments/journeys, which email to use for different communications?
• How should I behave with forms? For example, if I have different emails for different roles in a related table, how would I match them with existing contacts
• And if I match them to that contact with flows, then for example, with event forms, I will need to send an email confirmation, and Journey is set up to send it to emailaddress1.

So, for forms, I assume the obvious approach is to use leads, not contacts, but then I will need to create an event registration for a lead, not a contact? How would I then see this history?

Thank you to everyone who finds time to answer it
