It would be nice if when we're using the "Email inc. additional emails" functionality, it would just automatically use the "primary" email addresses for Person 1 and Person 2 on a record. It's hard to remember (or, get everyone in the firm to remember) to mark Person 2's primary email address as "additional", but if we don't, they get left out of any emails we're sending to the household. I like the "additional" checkbox if one person has multiple emails they want us to use, but not for Person 2's primary contact method.
