I e-mail, and my T has reassured me over and over that it is okay. She can't respond to all of my e-mails, but ones that are urgent she replies rather quickly. She keeps telling me I am a good writer (i don't believe her), and it is a way for me to tell her things that I have trouble saying face to face.

I know other clients text her (i only ocassionally do), so I am assuming they e-mail her as well.
