I use email with my T but it is something we agreed on from the start. I need that contact in order to heal from everything. He could have said "No" when I asked him in our first session. He said Yes. I even offered to pay for his time. He will reply if I say "reply needed" ... And he may reply to others. He may or may not even read what I send him. That kinda hurt for a while but I realized it was also a part of the deal.

I think it is just important to know exactly what the rules are in these situations. That keeps the client safe.
