It is often for connection and sometimes to let her know about things going on between sessions. Also, I almost always write an "afterthoughts" email to process our sessions immediately afterward. Her policy is to reply to emails when I specifically ask for a response, though she often replies when I don't.

Honestly, she seems to be the same through email and in session. She doesn't write a lot, so sometimes it might seem abrupt, but her words and tone are warm like in session. She does have a huge confidentiality clause as her signature, which, at this point in our relationship with her always pushing 'reply' to my emails and my address firmly in her contacts, it seems kind of silly. She did recently decide that because texts aren't as private I shouldn't send anything but scheduling texts--no more personal ones (she has an iPhone which pops up the message that anyone looking at the phone could potentially see--whether another client if it's on her desk or her husband if she's at home).
