Is Your Subject Line a Door or a Dead End?
Imagine walking up to a store with a dusty, broken sign that says “Stuff Inside.” Would you go in? Probably not. That’s exactly how your email subscribers feel when they see a vague or uninspiring subject line in their inbox.
Your subject line is the front door to your email. A great one invites people in, while a bad one gets ignored—or worse, sent straight to spam. In fact, 47% of email recipients open an email based on the subject line alone. So, how do you craft subject lines that get clicks? Let’s break it down.
The Secret Sauce of an Irresistible Subject Line
Think of a good subject line like a movie trailer—it gives just enough intrigue to make people want more. Here are some tried-and-true strategies:
1. Keep It Short and Sweet
Most people scan their inbox in seconds. If your subject line is too long, it gets cut off—especially on mobile. Aim for 6-10 words or under 50 characters.
✅ "Flash Sale: 50% Off Today Only!"
❌ "We have a special offer just for you that you won’t want to miss!"
2. Personalization = Connection
People love seeing their own name—it’s human nature. Emails with personalized subject lines are 26% more likely to be opened. Try using:
- First names: "Sarah, You’ll Love This Exclusive Deal"
- Location-based details: "Hello from Boston: A Special Offer for You!"
- Purchase history: "Your Favorite Sneakers Are Back in Stock!"
3. Create Urgency and FOMO
When something feels like it’s slipping away, we act fast. Use time-sensitive phrases to spark action:
- "Only 3 Spots Left! Sign Up Now"
- "Last Chance: 24 Hours to Save 30%"
- "Your Exclusive Offer Ends Tonight!"
4. Spark Curiosity Without Being Clickbaity
If you make readers wonder, they’ll click to find out more. But don’t overpromise—misleading subject lines damage trust.
- "The One Email Marketing Trick You’re Not Using"
- "We Need to Talk About Your Open Rates…"
- "Guess What? You Just Won a Free Gift" (only if they really did!)
5. Use Numbers and Lists for Clarity
Numbers stand out in a sea of text. They also set expectations.

6. Emojis: A Little Goes a Long Way
Emojis can make your subject line pop, but don’t overdo it. Keep it relevant:
- "🔥 Huge Sale—Up to 50% Off!"
- "⏳ Time’s Running Out—Your Coupon Expires Tonight!"
- "🎉 You’re Invited: VIP Access Inside"
Avoid using too many or spammy symbols (like 💰💰💰) that may trigger spam filters.
7. Test, Test, Test!
Even the best marketers don’t guess—they test. Run A/B tests to see what resonates with your audience.
- Try different word choices ("Flash Sale!" vs. "Hurry—Sale Ends Tonight!")
- Experiment with personalization ("Hey [Name]" vs. "Exclusive for You")
- Test urgency vs. curiosity ("Final Hours to Save" vs. "You Won’t Believe This Deal")
What NOT to Do: Common Subject Line Mistakes
❌ Using Clickbait – Don’t promise something you can’t deliver. If your email doesn’t match the subject line, expect unsubscribes.
❌ Overloading with Caps & Punctuation – "OPEN NOW!!! GET YOUR FREE GIFT!!!!" screams spam. Keep it natural.
❌ Being Too Vague – "Check This Out" doesn’t tell the reader why they should care.
❌ Ignoring Mobile Users – Keep it concise so it doesn’t get cut off on smaller screens.
