Yearning, it's a very good email. If she doesn't mention it, simply ask her "did you get my email" at the beginning of the session. If she didn't, giving her a hardcopy would be a totally non-awkward thing to do. Bring a printout as a backup, just in case, even if you don't feel like giving it to her.

My t never responds to emails (unless it's scheduling stuff), but at the beginning of the session mentions something like "you sent me an email" and then we talk about that.

Good luck for your session!
