You won’t believe it! (Actually, I think you will.) Clickbait headlines often work on social networks and across the web, but they’re not a good idea for your marketing emails.

That’s according to “The Art and Science of Effective Subject Lines,” a new study out today from Return Path. The company looked at more than nine million emails sent by “prominent global brands” to more than two million consumers between January 1 and February 28 of this year.

Return Path found that emails with clickbait-like words in the Subject line had lower read rates when compared to similar emails sent with less clickbait-like subject lines. For example, emails using the phrase “secret of” performed well below average (almost nine percent) and the word “shocking” led to a 1.22 percent drop in read rate. On the other hand, when the wording used more tame language like “get rid of” and “what you need to know,” read rates performed a little above average.


The study also found that subject lines with language suggesting a sense of urgency were among the best performers across the board. The phrase “still time” performed a whopping 15.54 percent better than average, and similar phrases were successful, too:

  • expiring: 1.63% above average
  • last chance: 1.05% above average
  • limited time: 3.05% above average
  • now: 0.24% above average
