I have noticed that some organisations, not just modelling ones, seem to be uncomfortable with dealing with Emails. Visit - fine; phone - fine; email - no response. Not sure why, but if you do have an email contact then people expect you to service it in the same way you deal with other contacts. Gives a very bad impression otherwise as this thread demonstrates. Wading through the spam isn't a valid excuse as there are filters available which remove the bulk of it. it's also pretty obvious when you are looking at spam so it can easily be deleted. Maybe it's a computer literacy issue in this case?
