Well, email works really well for me, as T checks his email a zillion times a day, so I can be assured he will get my message. He is not very good with phone messages or calling back, so I can't think of a reason I would ever use that method over email. I email him only about stuff like canceling or rescheduling appointments. I save the therapy stuff for face to face. I agree that for some people who email their Ts about substantive issues, it seems to blow up in their faces and they get hurt or misunderstand the messages. In those cases, it does seem prudent to stop the emails and wait until session or do phone calls instead.
