Crafting subject lines that get clicks is one of the most important skills you can develop in email marketing today. A subject line is the first impression you make in someone’s inbox—and it’s often the deciding factor in whether your email gets opened or ignored. For example, “Your 5-Minute Fix for Overwhelming Mondays” is much more likely to be opened than “Weekly Newsletter #4.” In this article, you’ll learn three simple and powerful strategies to write subject lines that your audience can’t resist clicking on. These include using curiosity-based phrases, adding personalization, and timing your sends just right. The phrase subject lines that get clicks refers to email subject lines that drive recipients to open and engage with your emails, increasing your chances of building relationships and making sales.
When your subject lines are on point, your entire email strategy becomes more effective. You’ll reach more readers, deliver your message, and grow your business more consistently. These strategies are especially helpful if you feel like your emails are getting ignored or lost in the shuffle. With each tip, you’ll also get clear steps for using them immediately in your business. Our goal is to boost your open rates and help you feel more confident every time you press “send.”
Here’s what we’ll cover:
- How to spark curiosity with just a few words
- Why personalization increases your chances of getting opened
- How timing your emails can make all the difference
Let’s explore how each of these strategies will help you write subject lines that get clicks.
Spark Curiosity with a Hint of Mystery
One of the easiest ways to get someone to open your email is to make them curious. Curiosity pulls people in because they want to know what they’re missing. A great subject line should leave just enough unsaid to encourage the reader to click and find out more. Think of it like a movie trailer—it teases the plot without giving away the ending. Phrases like “You won’t believe what happened…” or “One simple trick to grow your list” make people stop scrolling. When writing subject lines, you’re not just listing what’s inside—you’re creating interest. This is especially helpful when you want to promote a new product, service, or offer.
The Benefit of Creating Curiosity
Creating curiosity in your subject lines can instantly boost your open rates. When people are intrigued, they’re more likely to take that next step—opening your email. A well-placed question or mysterious teaser can help you stand out in a crowded inbox. This strategy builds anticipation and encourages engagement. It also makes your emails feel more personal, like you’re sharing a secret or inviting someone into something special. When used consistently, curiosity-driven subject lines help build trust and a pattern of interaction with your readers.
Why Curiosity-Driven Subject Lines Matter
These subject lines matter because your audience sees dozens (if not hundreds) of emails a day. Most of them look the same, and it’s easy to ignore or delete without opening. But when you spark curiosity, you interrupt that pattern. You make the reader pause and think, “Wait, what is this?” That tiny moment of interest gives your email a chance. Over time, this helps increase brand recall and encourages consistent readership. And when readers regularly open your emails, they’re more likely to buy, share, or respond. Curiosity also aligns with human nature—we’re wired to seek answers and complete “gaps” in information. This psychological pull can make your email marketing feel more engaging and fun.
How to Implement This Strategy
Start by brainstorming questions or open-ended phrases related to your topic. Think about what would make you curious if you saw the email in your inbox. Use fewer than 50 characters if possible—shorter subject lines tend to perform better on mobile devices. Avoid giving away too much; tease the benefit or outcome without revealing all the details. You can also try using numbers or phrases like “Here’s how” or “This one thing.” Test your subject lines by sending them to yourself first. If it wouldn’t make you want to open the email, tweak it. Finally, track your open rates to see which curiosity-based lines perform the best, then replicate what works.
Add Personalization to Connect More Deeply
Adding someone’s name or mentioning something specific to them in a subject line creates instant connection. It makes the reader feel seen, and that’s powerful. Personalization doesn’t have to be complicated or invasive—it can be as simple as “Hey Sarah, this one’s for you” or “Your business deserves this quick win.” It tells the reader, “This isn’t just another mass email.” When you tailor your subject line to your audience’s interests or needs, your email becomes more relevant and welcome. This level of care often leads to better engagement and results.
The Benefit of Personalized Subject Lines
Personalized subject lines help increase trust and relevance. When someone feels like an email was made for them, they’re much more likely to open it. This builds stronger connections with your audience and leads to more responses and conversions. Using names, preferences, or past behaviors helps you speak to your reader’s heart. It also shows that you’re paying attention and value their time. The more connected someone feels to your message, the more likely they are to click, read, and take action.
Why Personalization Increases Clicks
Generic subject lines are easy to ignore. But when a reader sees their name or a direct reference to something they care about, it grabs their attention. It shows that you know who they are and what matters to them. This deeper connection builds over time, creating a loyal and responsive audience. Personalization also reduces unsubscribes and increases email retention rates. When you meet your readers where they are, they’re more likely to stick with you. And let’s be honest—getting emails that actually feel helpful and relevant is rare, so when you do it well, you stand out.
How to Use This Strategy
Start by collecting names and simple preferences when people join your list. Use email software that allows merge tags to include names in your subject lines automatically. Try segmenting your list by interest, location, or recent activity to make your messages more targeted. Don’t overdo it—keep the personalization natural and aligned with your tone. Use phrases like “A tip just for you” or “Something we noticed you’d love.” Test a few variations and watch how your audience responds. Over time, you’ll find what works best for your community.
Send Your Emails at the Right Time
You could have the best subject line in the world, but if it arrives at the wrong time, it might get buried. Timing plays a major role in whether or not your audience sees—and opens—your emails. Think of your own inbox. Some emails hit right when you’re available to read them, while others get lost in the shuffle. Understanding your readers’ habits and schedules helps you land your message at just the right moment. This boosts the chances that your subject lines that get clicks will actually work.
The Benefit of Perfect Timing
Well-timed emails are more likely to be seen, read, and acted on. If your audience tends to check emails in the morning, sending messages in the afternoon could mean they’re missed. When you align your send times with your reader’s daily routine, you increase the odds that they’ll engage. This helps your overall email performance and ensures your efforts don’t go to waste. Sending at the right time also shows that you understand and respect your audience’s time.
Why Timing Makes a Difference
Timing matters because attention is limited. Your audience is juggling work, family, and life, and they don’t always check their inbox at the same time every day. By analyzing when your emails get the most opens, you can start to see a pattern. This insight gives you an edge. When you consistently hit that “sweet spot,” your audience begins to expect and look forward to your messages. It’s not just about being seen—it’s about being remembered. Good timing helps build that kind of consistent engagement over time.
How to Use This Strategy
Start by testing different days and times to see when your emails perform best. Many business owners find that Tuesday and Thursday mornings work well, but this varies by industry and audience. Use your email platform’s analytics to track open rates and adjust accordingly. Try resending emails to people who didn’t open the first time, changing the timing slightly. Also, consider your audience’s time zone—what works at 9 a.m. for you might not work for them. Stay consistent with your best-performing time slots, but revisit them every quarter to see if anything has shifted.
