Techniques That Get Your E-mail Opened

In its welcome message, bluefly.com sent a discount offer and placed it in the subject line—a proven tactic. But beware, customers get used to formats and stop opening e-mails. So mix it up!
Subject line: Special 20% Discount For You!
First few lines of text: Congratulations and welcome to Bluefly!
Closing: Now that we’ve got you swooning, don’t delay. Compose yourself, cool off, and log on (http://web site address). The fashion is waiting.
Happy Shopping,
Indigo Mosca
