Are you wanting a substantive response? I've had a similar email issue and I get assured she does read them but her response is a 1/2 liner, picking up v briefly something in the email and then referring to discussing it in the next session. I've sort of a bet with myself when she'll run out ideas to say the exact same thing in different ways but she's not failed me yet!

Also I kinda promised to bring up in session what ever I wrote to keep the intensity in the sessions

Could this be an option?
