It's not normal nor is it professional and it's basically rude to not acknowledge an email, but these girls do have other lives and this is a weird profession that gathers all kinds of providers. She may be away she may be busy or she may just be inconsiderate but  2 emails in 3 days is hardly stalking.  

If you've never seen her than it's unlikely it's personal as to why she chose to ignore you, call it an oversight as benefit of the doubt and move on.. Plenty of lovely ladies happy to show you a good time

Most will/should at least acknowledge the initial email. I know my standard response is that I'll be in touch once screening is complete. But I have known some very low volume independents who may only check their "work email" once a week. But receiving no response if you fail screening for whatever reason is pretty common, especially if you're blacklisted somewhere. Most providers won't tell you if they found you were blacklisted, because they don't want you to try to use different contact information next time. Even if you failed for another reason, they want to avoid conflict by not telling you, because some guys can get very upset by it and seek revenge.

Thanks Nyx_GG. So you're suggesting it is normal to not acknowledge the original e-mail while you're checking the references or if she decides not to see me (due to my references not clear). I must admit I find that a little strange. I've had previous instances where the provider acknowledged my e-mail in a hours and then took 3-4 (sometimes more) days to check the references and get back which- for the reasons you pointed out- is totally understandable. I can't think of any problems anyone can have with that.  
   
 My OP was about the # of attempts a hobbyist should make if he doesn't get an acknowledgement. As a few people suggested 2 sounds like a fair number. But I'm going to stick with just one for future. If she doesn't acknowledge -with due respect - that's loss in her income.  
   
 As I said in one of my previous responses, in this particular case (a first for me), I've sent just two e-mails and not a flurry as appears from a few responses. End of topic for me. No harm no foul .

Sometimes it can take several days to screen a new client, I've even had times where it's taken weeks to hear back from some references. Two to three business days to complete screening is common in my experience. Repeated contacts while still in screening could be viewed as a red flag to many providers. Problem clients, and LE, will try to rush screening hoping that you'll get sloppy and let them through.  
     
  Or perhaps you just didn't pass screening, and she's trying to avoid any potential conflict by ignoring you. Repeated contact attempts at that point is just more likely to convince her you're to be avoided, and may result in her blacklisting you.  
     
  My advice is to make one request, and if you haven't received a response within three business days, then I feel it would be acceptable to send a follow up email to check on your status. If you still don't get a response, then it's time to move on.
