Been working good for me. Using CC option and the popup always sets it when I write a reply or compose an e-mail. I'm sure there are other options, but this is fine for me.

Stupid pop up window and the CC or BCC address always shows an add option. It is quicker for me to add a CC address then wait for this app to rotate through its functions. They make it hard to find how to cancel your account. Stay away from this one
