...providers can get swamped with emails, many only have intermittent access to the internet, some are slow typers, lots don't really understand computers very well, and in the end you're gonna have to call anyway, so just cut to the chase and pick up the phone.

You can't delete a phone call, and usually there is more accountability on her side if you've actually spoken with her, or left voicemail.  That's not to say that VMs don't go unanswered either, but if I'm really jonesing to see a certain provider, I'll always call.  

Also providers appreciate phone calls, because it means the guy is probably more serious.  Actions speak louder than words, and a phone call is more action than an email.  The bane of providers are the "tire-kicking" men who like to dilly-dally with tons of get-to-know-you emails.  This is a waste of a providers time and energy, and IMHO is disrespectful.  Many providers don't use email for this very reason, too easy to abuse.  

All the providers on this board could tell us many stories of all the men who like to strike up email conversations, promising to book, wanting to set things up, blathering on about their life story, and then never making the call.  

If email is her only means of contact, sure, you have no choice.  If she's not responding to email then, that's another story, it means she doesn't want your business.  Best to move on to someone who does.
