I have my assistant respond to emails and always emails the day before to confirm . I always am available to respond to requests . I do not like request that ask whats on the menu. Or ask for selfies. I need to know its you.  
excuse my French READ MY FUCKING REVIEWS I am not inclined to email details about our session or send selfies.  
If you have a specific request i am happy to reply.

Bro what with asking what’s on the menu?  Use some common sense.  Read the reviews

Maybe ask them...?  

I doubt you'd get anything but a polite reply if you asked for what you're looking for. Maybe something like:  

"Hi! My name is _______, here's my screening info:  

I would love if we could talk a bit before meeting. Thanks!"

I met with Adeline not long ago.  Emails were through her assistant, and all were clear and concise.  There was one hiccup in the process that was out of everyone's control, and Adeline did email herself to apologize and reschedule. I found the process to be just fine. Our meeting went off without a hitch amd we had a wonderful time. I am looking to plan another date soon. If you read Adeline's reviews, you will get a ton of information about her and I don't know what else you would want to know.
