The importance of subject lines in emails

According to e-mail service company SubscriberMail CEO Jordan Ayan, most retailers never bother checking email subject lines to test if the words or phrases are being filtered by a spam filter or if they are being deleted without being read by the recipient. It was found that close to 40% of the attendees at a direct marketing trade association event never tested subject lines. Most consumers never bother opening a mail from someone they don't know and if you add words like 'free' or write all in caps then you are only ensuring your email goes straight to the trash can.

SubscriberMail recently listed problematic words and phrases in a white paper entitled “The Seven Dirty Words you can’t say in subject lines; plus 100 others.”
