My T has been consistent, replying to my emails typically within a couple of hours with brief (although still meaningful) replies, so this hasn't caused problems. His replies have given me immediate relief during crises even though they're usually just a couple of sentences. At other times, when I have a realization of some sort between sessions, I think I get even more insight or clarity as I try to articulate it in writing.

I see this as very helpful, but I do think he maybe should have stated what his email policy was right up front. I limit myself so it's less than one email per week on average, which has been fine, but I don't know where the limits are. Maybe T's don't want to state the limits up front because they don't actually want to encourage their clients to text, email or call? "Up to 4 emails a week" sounds like an invitation. Maybe the limits should be in the small print at least, so the T could point to it later and the client would not feel they were being rejected or punished?
