I see this issue has been going on for over 10 years. It's honestly not even something I thought I would have to even ask about, I just assumed that multiple email addresses would be supported. Even the rinky dink CRM platforms support this function.

Sure, I can create multiple email fields so that I have the emails, but it won't track the correspondence. The only way would be to create multiple contacts for one person. 

The other problem this creates is that when a person switches companies and you update their email, you lose all previous emails. So again, an additional contact would be necessary. I'm going to try to figure something out to make it work, but this really needs to be addressed. Especially since users have been asking for this in excess of 10 years.
