Kiya and Dalila, sounds like we have experienced something similar!
Angel, my T doesn't really do the phone (he has voice mail but often doesn't check it), so I guess they each have their way of communicating. I didn't get my T's email until he took on another professional role for me. When you have to change an appointment or something, playing phone tag can be so inefficient. (I don't use the email for therapy, or to give updates, usually just for logistics, which sometimes can get complicated because of his dual role!)
