this is the output of FYLD.com blockchain

If you CC them on an email, it somehow gets timestamped and added to their blockchain to prove you sent that email with that content at that time.

You ARE giving them a complete copy of the email, so yeah that's scary and sketchy as fuck, so probably don't do that.
