If you’ve clicked on this article, I bet you’re curious about the curiosity gap. Well, according to Campaign Monitor, “The average person sends and receives approximately 121 emails per day.” Personally, I have never met someone who wished they would receive more emails in their inbox. While email marketing campaigns can be a valuable tool due to the large number of individuals who utilize emails every day, it can be difficult to encourage your audience members to actually open the said email and read it all the way through. How can you improve your email open and click rates? The curiosity gap can put brain science on your side and encourage open and click rates.

Let’s check out how you can use the curiosity gap to your advantage!

What is the Curiosity Gap?

For starters, if we are going to implement a strategy, we should probably know what it is! The curiosity gap is defined as the missing space between the information that a reader is given (what they already know) and what information is being withheld (what they want and need to know).

Using the curiosity gap can encourage readers to stay engaged in a piece of content in anticipation of an answer that was foreshadowed or alluded to by a previous statement.

Think back to the last time you watch a favorite show of yours. During the first few minutes of the show, the narrator says something like “This week on Bachelor in Paradise…”. Then the screen shows short clips, without context, from this week’s episode leaving out important details. As an audience member, you see yelling, tears, and drama galore. Your brain wants to fill in the gaps and make sense of what is actually happening here! Who is that crying? Why are they crying? What will the outcome be? Producers do this purposefully! To capture your attention and keep your mind curious about the surrounding events encourage you to watch until the end of the episode. You can use similar psychology to encourage readers to open up and read your content, both in emails and blogs!

The Curiosity Gap appeals to brain science

Brain Science Behind It

The great thing about the curiosity gap is that it works in parallel with how the human brain functions naturally. According to Britaninica’s Curiosity Compass, “Epistemic curiosity [is] the drive to eliminate information gaps and learn new explicit information. When you feel that thirst to acquire new knowledge, your brain actually responds as if you are actually thirsty or hungry – that’s where the areas sensitive to unpleasant conditions light up.” As a business, why not use this to your advantage? You can essentially ‘quench your audience’s thirst for knowledge”!

Curiosity Gap – Ideal Placement

So, where should you place key phrases to utilize the curiosity gap in emails? The answer is the subject line. A 2021 Barilliance study found that “64% of consumers decide to open emails based on the quality of the subject line.” This one is the subject line like your bait while fishing for readers. If you can convince the reader’s mind that your email contains information that will close the gap of the information they want to know, they are more likely to open and read it!

However, it is important to consider the length of your title or subject line. Using a catching phrase can be helpful, but not if the phrase is so lengthy that it is cut off and cannot be viewed. This is especially important for mobile devices since the number of characters that can be viewed in the email subject line on mobile devices is even more limited than on desktops.

You can also include phrases related to curiosity at the beginning of the body of your email or article. Similarly to the reality TV episode example mentioned previously, this can encourage your readers to stick with your content until the conclusion of your piece.

Lastly, you can connect your content to current events that readers may already be curious about. For example, if you know that Selena Gomez is trending online right now, including a tie to her in your content may attract more of your audience’s attention.
