You get an email that only says

It clearly states my requirements when requesting an appointment. If they don't follow up meeting those requirements the email gets deleted without a reply.  

... cases where I send a polite request for an appointment with clear details on day/time preferences, and I get a response like this (real example):

or are simply new to the business. Also remember that TER ladies don't have the market cornered and if you don't reply someone will.  
When I started I was probably at fault but then I learned the etiquette etc.  
in all you can miss out on a potentially good, long term customer if not patient enough. This applies even to relationships but at the end of the day to each it's own and you can decide what's better for you.

I can tell you some stories!!! And it's about today's communications!!! If I could stab someone in the eye I would!!! Please RANT for me too!!!!

On second thought, it would depend on exactly who sent it.

I have a form letter that I copy and paste when I get such emails.  If they don't provide information after my form letter I ignore.  If they persist in communicating and still won't provide screening information I block their emails.  End of story.

Well I book exclusively through p411.  But in the event I were to contact through email,  I would first offer the target day and see if they respond that it is possible before I start blasting my references and other identifying information

What I do most of the time too

From this man's POV, there are 6, more like 20, MN women who,  
if they messaged me, "Get over here I need your attention for an hour or two"
I'd be in the shower, out the door, and in the car in under 10 minutes.
On the rare occasion that happens those women become instantly more interesting than they were 2 seconds ago.

When I email I wonder if the ladies think "what the &*^%.....I tend to write a detailed letter...I happen to love the spoken, written word so I love to write. What I get in return sometimes is a one line response....which leaves me thinking so much for putting your heart into it....just hoping I would get that in return....I guess I just answered my own question, lol....

That's easy...the effective way is to be pre-screened in advance for a lady on you "to do" list, then when the urge strikes she will have all the formalities out of the way, and then you can do the "are you available now?"  routine.

Is what happens in your session. Many ladies who absolutely rock your world in a session are very business-like in their communications. Your heartfelt letters are noticed and will serve as a great start that could lead to a wonderful session with a beautiful lady!
