I would email my first two Ts sometime before each session with all the things I wanted to talk about because I had a hard time opening up fully during session and that was slowing down my progress. With the first T I actually just guessed her email - she worked at a private practice and there was a general email address that would go through to the receptionist and I just edited that with my T's name and it went through. She asked me how I got her email so I had to tell her that I just guessed it because I didn't want to send personal stuff to the receptionist. She didn't seem to mind and let me email her before each session. My next T was at the same practice and I told her that I had been emailing my previous T before sessions and she said I can continue to do that with her if I need to so I did.

My current T said that I could email her if I need to after our first session but I don't know if that was just because there was a three week gap until my next session (because of Christmas). I didn't emailed her though. As far as organising appointments, I just do that at the end of our session each week. If I need to change it or cancel I will email her. She only works two days a week I believe so calling her on her days off wouldn't be appropriate.
