10 Tips to Write Powerful Email Subject Lines
Crafting the perfect email subject line is both an art and a science. It’s the first thing your audience sees, and it determines whether your email gets opened or ignored. To help you create subject lines that grab attention, spark curiosity, and drive action, here are 10 proven tips with actionable examples:
1: Avoid Spammy Words (With Examples)
Spammy words like “free,” “buy now,” or “limited time” can trigger spam filters and hurt your email deliverability. Instead, use clear, engaging language that avoids red flags.
Example:
❌ Avoid: “Get rich quick! Limited-time offer!”
✅ Use: “Discover the secrets to financial freedom.”
2: Keep It Relevant to Your Audience
Your subject line should align with your audience’s interests and needs. Irrelevant subject lines can lead to high unsubscribe rates.
Example:
❌ Avoid: “Check out our new product!”
✅ Use: “Boost your productivity with our new time-management tool.”
3: Make It Intriguing and Curiosity-Driven
Spark curiosity by teasing valuable content or asking a thought-provoking question.
Example:
❌ Avoid: “Learn about email marketing.”
✅ Use: “The one email hack that doubled my open rates.”
4: Ask a Question to Spark Interest
Questions engage readers by making them think and encouraging them to find the answer inside your email.
Example:
❌ Avoid: “Tips for better time management.”
✅ Use: “Are you making these 5 time-management mistakes?”
5: Keep It Short and Sweet (Ideal Character Count)
Short subject lines (under 50 characters) are more likely to be read, especially on mobile devices.
Example:
❌ Avoid: “Here’s how you can improve your email marketing strategy in 5 easy steps.”
✅ Use: “5 steps to better email marketing.”
6: Add Urgency to Drive Immediate Action
Create a sense of urgency to encourage readers to open your email right away.
Example:
❌ Avoid: “New course available.”
✅ Use: “Last chance to enroll—course closes tonight!”
7: State Your Offer Clearly
Be upfront about what’s inside your email. Clear subject lines build trust and set expectations.
Example:
❌ Avoid: “You won’t want to miss this!”
✅ Use: “Get 50% off our best-selling course.”
8: Personalise Your Subject Lines for Higher Engagement
Personalisation, like using the recipient’s name or referencing their interests, can significantly boost open rates.
Example:
❌ Avoid: “Tips for growing your business.”
✅ Use: “John, here’s how to grow your business in 2024.”
9: Use Numbers and Statistics to Stand Out
Numbers grab attention and make your subject line feel specific and actionable.
Example:
❌ Avoid: “Ways to improve your email marketing.”
✅ Use: “7 proven ways to improve your email marketing.”
10: Test and Optimise Your Subject Lines
A/B test different subject lines to see what resonates with your audience. Track open rates and adjust your strategy accordingly.
Example:
Test 1: “Boost your sales with these tips.”
Test 2: “5 tips to double your sales in 30 days.”
