I have seen many providers that are email only. Some who gave out a phone number only at the last minute to get directions,or a room number, and some who were strictly email right on through the date, without ever having a voice conversation.  

If there is a choice of email or phobe, I will always choose email. With ladies that only have a phone number contact, I usually use text. I'm not much of a phone call guy.

Not a single appointment was made by any of those dudes. Not. One. Directing them to my contact form didn't make one iota of a difference.  

My (admittedly limited) experience says don't bother. The ones who are worth your time know how to read and follow instructions.  

I have come to prefer email or better yet P411 for our first contact. I no longer try for last minute appointments and things seem to go much smoother. If my lady takes time to do good screening for everyone, I feel its safer for both of us, and last minute phone dates seem to me like good screening would be difficult......but I'm not a screener it's just my humble opinion.

Phone for the approach.  When to switch is her call.

Who tends to my phones but I reply to emails and look at contact forms myself. I find that Email only is also an alternatively specially if you don't have time to be on the phone. Some providers find that having the contact form filled out shows how serious the guy is but, that is not always true, some guys are old school and prefer to have the "human touch over the phone". I know girls who require the potential date to fill out the form and once screening is performed and he checks out, they will call him.  
Either way, I think that at some point you do want to establish phone contact in order to see if you click as communication and chemistry are essential on a date.

But, to each his/her own.  I see ads every day, some say phone only, some say email.  If you don't feel comfortable calling her, move on.  We all have our preferences.  Do what you're comfortable with.

...all info by e-mail. I expect to get a phone number after passing screening if one isn't posted somewhere. I only call on the day of the appointment to confirm in the morning & then to let her know I'm there so she can give me the room/apartment number. This is the procedure I have grown accustomed to since all of the ladies I see do it this way. I have seen one that is by phone but it's not my preferred way. I did also see one that wanted a phone conversation as part of screening. Once I've seen the lady a few times all of this is interchangeable. But I still initiate a date with e-mail.
I'd say stick with what your doing. It does make sense to me to text or call on the day of since the need for contact is more immediate.

the provider (she can answer me when time allows) and for me, the hobby phone stays in it's hiding place.

The only time I need the phone number is to let her know I'm leaving, now in the area and to get the room number of the incall.

Do what is best for you. Email helps in screening prior to waste of time calls. Some never do phone calls and keep it text or email..... I have to talk to the person in order to confirm. Many weirdos pass screening and are crazy via phone.  

It is completely upto you how you do it. Many great gals do email only. Obviously it works well for them.  

I like to get the personality before confirming, that is what I am comfortable with. I don't like much email/texting prior. Call. Plus it makes it easier for same day appts. Some gals take a few days to screen, I can screen in less than an hour if I get enough info.

Never a right or wrong answer on this.

As I use that as another part of my screening process. Kind of like how the eyes are a window to the soul, well I'm not looking into anyone's soul on the phone but a brief conversation can tell so much. The sound of their voice, the words they choose, etc give me a better "picture" of who I'm going to be entertaining.  Also my voice is another selling point and just adds to the anticipation.

Phone call guys are usually last minute, late night, and drunk. They also want to chat you up for a fkin hour and have jack off material, rarely provide screening info. and even if they "tell" you who their refs are, you still have to write the stuff down to go look them up. Email simply makes the most sense. Time wasting idiots are deleted, and you tend to the serious guys.

With phone calls, you don't find out who is full of shit until after you listen to them yap for a while, and it's far from discreet. Most married men and providers I know, are rarely alone or in a position to make or take phone calls at random. Men rarely leave a voice mail, and a provider has no clue when or if she should even call that number back. Bottom line...phones are trouble, and always have been. I have to use a phone for my agency, and I spend more time answering it, than making freaking money!

I'm going to continue to use email for first communication. Phones are way too much of a pain in the ass. I do see their usefulness as a screening tool, though, both as info to search and to 'read' the voice of the prospective client. The few times I have been contacted by a person that I didn't want to see, I found them on the blacklists by googling their phone number.

Everywhere but

I put a phone number on all ads EXCEPT the ones I post in Milwaukee. It has to be email only first.. So much general stupidity here. If I put a number in my ad, I get calls like "I  think I want to see you but are you Black or half Black? Ohh, I only like white women, can I have a discount?" Do I get angry at the idiots? Nope, because I'm almost finished school & I'll be the one injecting their stupid butts with antibiotics to cure that funky gonorrhea they got from the street corner.
