When it comes to email marketing, the subject line is the first—and often only—chance you have to grab your reader’s attention.
A great subject line can make the difference between someone opening your email and sending it straight to the round file.
As I mentioned in last week's newsletter, 47% of email recipients decide
whether to open an email based on the subject line alone.
So, what's an email marketer to do?

Want To Boost Your Email Open Rates? Craft Effective Subject Lines
Standing out in
overcrowded inboxes these days demands creativity AND an understanding of best email subject line practices.
Let’s dive into the strategies that can help you craft compelling, effective subject lines every time.
1. Keep It Short and Sweet
In today’s world, we’re bombarded with messages from all angles—social media, work emails, personal communication, and more.
People have limited time and attention, so getting to the point quickly is key.
Best Practice: Aim for subject lines that are 6 to 10 words or 40–50 characters long. They're easier to read at a glance and less likely to be
cut off in mobile previews.
Example:
Instead of: “Here’s an update on our new product launch and what you
can expect from it”
Try: “Exciting News: Our New Product is Here!”
2. Create a Sense of Urgency
We are naturally drawn to scarcity and urgency. Using phrases that imply time sensitivity or limited availability can spur action and increase your open rates.
Best Practice: Use words like “last chance,” “limited time,” “don’t
miss out,” or “ending soon” to create a sense of urgency.
Example:
“Last Chance: 30% Off Ends Tonight!”
“Only 5 Spots Left for Our Exclusive
Webinar!”
3. Personalize When Possible
Personalization isn't limited to addressing the recipient by name (though that can work, too). It’s about tailoring the
message to your audience's preferences, interests, or previous interactions with your brand.
Best Practice: Use data such as location, past purchases, or interests to make the subject line feel more relevant and individualized.
Example:
For a returning customer: “Hey [Name], Your Favorite Product is Back in Stock!”
For a segmented list: “Just for You: New Yoga Gear You’ll Love!”
4. Use Action-Oriented Copy
Strong verbs and clear calls to action can increase engagement. People are more likely to open an email if they know exactly what they’ll get out of it.
Best Practice: Use actionable verbs like “discover,” “unlock,” “claim,” “join,” or “get” to encourage the reader to take the next step.
Example:
“Unlock Your Exclusive Discount Now”
“Get Your Free Guide to Success”
5. Be Clear, Not
Mysterious
I get it...it’s tempting to create mystery and intrigue with a subject line. Don't! You run the risk of misleading your readers. Clickbait tactics (e.g., exaggerated or misleading subject lines) can result in high open rates but often lead to high unsubscribe rates or even spam complaints.
Best Practice: Make sure your subject line accurately reflects the content of your email. Transparency builds trust with your audience.
Example:
Instead of: “You Won’t Believe What Happens Next”
Try: “Here’s What’s New in Our Latest Collection”
6. Test and Adjust
Accordingly
What works for one audience might not work for another, and subject lines are no exception. The best way to know what resonates is by testing different approaches.
Best
Practice: Run A/B tests on your subject lines. Compare the performance of different wording, length, tone, and urgency. Track open rates and other engagement metrics to identify what works best.
Example:
Test subject lines like:
- “Get Ready to Save Big on Your Next Purchase”
- “Exclusive Deal Inside: Save 25% Today”
7. Use Numbers and Lists
People love digestible, easy-to-read content. Numbers and lists are a great way to present information in a way that’s instantly clear and appealing.
Best Practice: Use numbers to quantify the value or benefits you’re offering. “Top 5 Tips,” “3 Ways to Improve Your
Business,” or “10% Off Your Next Order” are great ways to grab attention.
Example:
“5 Ways to Make Your Morning Routine Better”
“10% Off + Free
Shipping — Just for You!”
8. Use Emojis Carefully
Emojis can add personality and fun to your subject lines, but they should be used sparingly. When used
appropriately, they can help your email stand out in a crowded inbox.
Best Practice: Stick to a couple of relevant emojis that enhance your message without making the subject line look cluttered or unprofessional. We've all seen those and clicked away!
Example:
“🎉 Celebrate With Us — 20% Off Everything! 🎉”
“🍂 Fall Sale: Save Big on Cozy Items!”
9. Appeal to Emotions (My Personal Favourite!)
Humans make decisions based on emotions, even in business. Crafting subject lines that evoke curiosity, joy,
excitement, or even empathy can be a powerful motivator for people to open your emails.
Best Practice: Think about the emotional impact you want to create. Are you offering excitement, relief, inspiration, or solutions to problems?
Example:
“Feel the Joy of Giving – Exclusive Gifts Inside”
“Ready to Transform Your Morning Routine?”
Keep Experimenting and Learning
Crafting effective subject lines is as much an art as it is a science. It requires a balance of creativity, psychology, and testing.
The more you experiment and learn from your results, the better you’ll become at creating subject lines that resonate with your audience and drive more opens.
Remember, the subject line is your first opportunity to make a great impression—don’t waste it!
Whether you’re driving sales, promoting content, or simply keeping your audience engaged, a thoughtful, well-crafted subject line can make all the difference.
