I will generally respond to such queries, but if I've had a number of similar queries that day, I will refer you to my site. It's annoying to answer those emails when that information is clearly laid out on your site (in terms of rates) and in reviews (in terms of location, services offered, etc). A little research can go a long way.
I also don't like discussing services, it takes the fun out of the actual appointment (if it happens). As well, I prefer messages from gents who sound as though they actually want to see me and they aren't just messaging every SP on CERB looking for the best rate.
