My old Blank Slate T did not allow emails or texts but I could ask her to call me if I was having a really hard time. My new T allows emails and always responds with something thoughtful. I texted her one time when I was running late but in general would not use texting as I don't want her to think that she has to stop whatever she is doing to reply to me. I'm happy with the emails! I try not to abuse it and so far so good.

If your T said that she doesn't mind, then take her at her word.
