Is It Safe to Email Editors? Spam Filters Are Causing Unexpected Problems
It wasn't so long ago that freelance writers hesitated to email editors because email queries and other communications might not be the right form. Now comes word that as many as one email in four never gets delivered, even email that the intended recipient wants. This startling number comes from 'More e-mail scandal' an article by Brian Livingston on InfoWorld's web site. Granted, most of the comments and research there is aimed at opt-in email, but it's apparent that other, legitimate emails are also going missing. The problem is twofold: spam and spam filters.
