As one of the people UTR who doesn't post much and doesn't write reviews, I will often send an e-mail to someone whose ad in Eros or BP appeals to me and I'd like to learn more about, but most do not respond.   I do it to know as much up front as possible before making any decision and develop some kind of e-mail rapport.  So my question is why does someone who makes e-mail communication possible, not respond to e-mails.  Sounds like a stupid business practice.

... they want your business. Try asking this question - Can I see you for one hour on xday at ytime.

Only those who are desperate for biz will bother to respond. The hot girls, the ones that you never heard back from, are busy answering real appointment requests and seeing guys.

And discussions. This site is a plethora of information. But what you do NOT do is email ladies with questions. They do not exchange info like that over emails. It can be used as evidence if you are L.E. the email process is for setting up appointments and being screened. If you have a question that you MUST ask her then you better ask it in very general and vague, non descript lingo. Or they may feel you are LE trying to set them up.
Respect the process.

I alwayas anwser emails because some people can only communicate via e-mail. If a provider doesn't want emails then they should not put that down as a way of contact. That is just my opinion.

Nothing like being attacked for trying to get as much information as possible before making a decision.  Not everyone has the ability/privacy to inquire about rates or general location from their office.  Midtown east can range from Third and 32nd to Lexington and 55th and general location is an important thing to know if you have a certain amount of time during the day.  And if LE wanted to bust anyone they wouldn't first send an e-mail-they'd call.

the sites you have chosen. Backpage girls are not into communication and Eros is, well, awful. Try private messaging on TER. Go to Date-Check or Preferred411. Maybe your luck will change.

....depends on what you're saying/asking.  Many reasons (some good, some bad) why an email will be ignored/deleted.

It's kinder and gentler there.  But it's true that just emailing out of the blue with questions won't get you far.  Start by doing your homework and seeking girls who are either on TER, P411 or Date-Check and also have web sites.  Between these sources you can answer all your questions without pestering the providers.  Then, once you know who you want to see, contact them by whatever means they ask for on their site.  Some prefer a phone call, some an email, some you can PM here or PM on Date-Check and P411.  Tell them you love their pictures and reviews and would like to set up an appointment.  Present the screening info they ask for on their site, or list your other creds like your P411 and DC listing info and provider OKs, or TER whitelists.  Some will ask for your board handles, but many guys want to remain anonymous.  If your other references are good you might get by.

Explaining to you why nobodies emailing you back. Don't ask next time. Sorry you feel attacked.

My experience jibes with inicky46.  You just have to be smart about what you e-mail...if a provider offers an e-mail address, then it's fair to send an e-mail.  But for reasons others mentioned, it's stupid to ask detailed questions in that mail.  Usually, a simple question like "are you available on X day at Y time" will get a response that is either "yes" or "no" and "I need the following information before we continue" or some secondary means of communication ("call my assistant to firm up an appointment").  Some providers PREFER e-mail; others don't use it.  Remember, it works both ways - they don't know who you are, and you don't know who they are, so don't send and don't ask anything detailed.

Really, you actually said that....ROFL.

You're just using the wrong technique. You have convince the provider that you plan to book her services. So, in your first email, start by saying where you saw her ad and that you're interested in booking her for whatever (one hour incall, etc.). You're available at such and such times, what's her availability? And, by the way (now you ask your first question). Now she has an incentive to answer your question. She'll probably try to advance the sale in her next email and ask you for screening info. You can either give her your info, and ask your next question in your next email, or take a chance and say something like, "Great. Before I give you my screening info, I just want to make sure you offer the services I'm looking for." Then ask your question. The more you convince her you're for real and you're ready to book her, the more likely you are to get a response.

Whether the response is reliable, though, is something you then have to evaluate.

Finally an answer with some useful advice.  Thanks Monk.
