With fun, engaging creative, Yesmail spread the word about an HP clearance event. At first glance, the email looks like a static email, with art displaying HP products. Then poof! One by one they begin to disappear in a puff of smoke. The playful message that shoppers needed to hurry or miss the best deals was effective: Compared to the same event the year before, the 2012 campaign saw a 132 percent lift in clicks, a 37 percent lift in conversion and generated a 29 percent lift in revenue per message sent, even with a send volume higher than that of the previous year.
