How many emails are appropriate or usual to set up a first date?  I am finding that Florida seems to like quite a few while up north, less in writing is preferred.   A first email sharing reference info and a brief introduction is lovely but I am uncomfortable with excessive emails before meeting.  How much is too much?   Thanks for your thoughts...

will send a reminder email at the 2 week point and then 1 week ahead and finally 48 hrs. ahead.  

I don't like too many emails, either, as a provider. All my information is either in my reviews, website, or ad. All of my information is there. I often ignore emails with one lines/sentences pertaining to "what are ur rates" "what do u offer" "do you offer A B C or D" etc. etc., because all of that is already covered. The emails I will reply to, yet with slight annoyance, are the ones that simply ask if I'm available on this day at this time. This just takes up a lot of time and too much back and forth, especially if I have to wait for your responses. I try to mention it in my ads that when contacting, please include ALL information of your first initial inquiry, such as time/day you'd like to meet, for how long, membership name, where you're staying, and references. That way I can plan and verify, then respond promptly to confirm. If dates are scheduled in advanced, then I follow the same process of confirming a week ahead, the day of, then about an hour or so before our scheduled time to let you know I'm getting ready to leave.  

I 'm in Florida and I like to send one email with my screening  details and the proposed time for our date.  If all is ok with the lady, that's it.  Done deal.  Not sure what else there is to say.  I'm not looking for a pen pal.  

e-mail me over 50 times. I cancelled our meeting. Then he e-mailed me again two months later, I decided to see him. He was a newbie back then and didn't know better. Lol! Now he's one of my favorite clients. It's funny how things work itself out.

...told me that a gentleman E-Mailed her more than 60 times then finally asked if she offered BBFS.  

A few emails are good for me but will not talk about anything sexual. I like an introduction with things that will make me feel comfortable meeting someone new. Playful banter and flirting can only heighten our experience. I also require a get-acquainted phone call which some gentlemen find a little inconvenient. I like to hear the gentleman's voice and pick up on their personality. I'm not sure if I'm alone in this communication or if other ladies do the same.  

Are they intrusive? Did the gentleman provide you with your required information? If you have to go back and forth and you are not making any progress it is time to end it.  A serious inquiry will have done his due diligence and will not waste your time.   If the date is set a couple of weeks or months in advance, I never did mind a little flirting and banter back and forth to keep the fun going.  
Guess there really is no right or wrong way. What ever you are comfortable with is how you should run your business.
