Quick Email to existing customers
Once in a while we just want to send a quick email message to a customer, but still have it appear through their portal (to be able to track it with their account).
For instance, someone wrote "please update our billing email address to firstname.lastname@example.org" on a piece of paper along with their mailed in payment this month. It would be cool to make a quick email in their account that says "Hey. We just updated your email as requested. Thanks!" Without creating a ticket, and still have everyone know that it was taken care of.
Not to replace emails entirely, but to just have a basic quick communication available. Maybe?
