I do not agree at all.
Messers are part of the game, always have been and always will.
But certainly not 80% of email enquiries are from dreamers and timewasters.
We are now in the age when an email is seen as a viable means of contact, solicitors, accountants, estate agents even doctors email day in day out, there is no need to pick up the phone for general enquiries these days.
If you sent me that cut and paste message as a potential customer i would certainly not want to deal with you.
