Never have any contact with my regular therapist outside of sessions, unless one of us needs to reschedule or something. It's much the same with my uni therapist/mentor, but I have texted her a couple of times just to let her know that I did something she asked me to do as well as specifically requesting that I let her know once I'd done it, lol. There was also one time when she looked really sad as I was leaving at the end of my session; I think she felt like she hadn't been able to help me the way she would have liked to, so later that evening I sent her a text saying that I had gone straight home and completed something for my coursework and that our session had actually helped me. She replied saying "thank you for telling me." So it will just be little things like that, I suppose.
