In this series, we share tips to create engaging copy for your buyers, from crafting effective emails to e-books, and more.
In email marketing, subject lines are the first part of your message that readers encounter. After all, if your subject line doesn’t grab their attention, then your readers won’t open your email or click through to access your content, a product demo or other offer – and they’ll never see your fine-tuned copy and CTAs. Are you feeling the pressure to make your subject lines pop? To take some of the weight off your shoulders, we’ve boiled down the most important takeaways for formulating subject lines that are eye-catching and get your core message in front of your audience. As a copywriter that writes dozens of subject lines each week, I leverage these strategies every day.
Let’s begin by placing ourselves in a reader’s position. On her train ride into the office, Brenda checks her email on her smartphone. Her inbox is crammed with 19 new emails. The first subject line reads: Six remarkable reasons why…
Subject line real estate
Clocking in at 26 characters, Six remarkable reasons why … falls within the typical range that a mobile email app previews: 25 to 30 characters of limited real estate. To unlock the remainder of that subject line, Brenda would have to open the email. But why would she? There’s no incentive; those 26 characters fail to illuminate the value with which the email can provide her. She deletes the message.

Here’s the subject line in its entirety, at 58 characters. The clipped-off text informs us of the email’s purpose, a subject of great interest to dance-enthusiast Brenda. But because that information wasn’t readily available to her, Brenda disregarded the email – an understandable response to an overflowing inbox. The email’s sad fate could have been avoided by frontloading key words, as shown below:
6 ways dancing boosts health
At 28 characters, this subject line frontloads key words and would likely appear in its entirety on a mobile device. Though crafting short subject lines can be a successful strategy, it’s not the only strategy. You can certainly leverage more characters, and if you do, we recommend using 60 or less. As you write longer subject lines, remember to frontload the most critical and relevant words.
Tactical messaging advice
Balancing subject line length while packing in your key terms is just one step you should take toward getting your message seen. Now we have a second balancing act for you: teasing information. This means engaging your readers with enough material to pique their interest but not so much that you give away all the value of your subsequent copy. For recipients to open an email, they have to believe that there’s more to discover – so don’t divulge all your information at the outset. Consider the difference between these subject lines:
- Dancing improves heart, bone & mental health
- Myriad health benefits of dancing
Yes, #1 is informative and thorough, but it fails to encourage readers that they have more to learn. Brenda could look at that subject line, digest the information it conveys, then continue scrolling, satisfied to have a new fun fact. Dissimilarly, #2 could lead Brenda to wonder what those health benefits are. To uncover the answer, she would have to open the email.
So, teasing information is one best practice for subject line crafting. Keep reading to discover seven more strategies for leveling up your subject lines.
