I would love to be able to send emails bcc to multiple constituents (so that they can't see who is on the email thread), AND have that email show up on each of their individual timelines as an interaction. It's so disappointing that I have to put everyone in the "to" line in order for it to be recorded. :(
I would like to see this as well. It's not professional to share email addressess when sending a bulk email, so being able to BCC Bloomerang while also BCCing all other emails would be a great solution!
