10 Proven Email Subject Lines That Skyrocket Open Rates

Email marketing is one of the most effective channels for engaging your audience, but even the best content won’t matter if your emails remain unopened. That’s where subject lines come in—they’re your first (and sometimes only) chance to grab attention and entice a click.

Crafting the perfect subject line requires a mix of creativity, relevance, and a dash of psychology. To help you, here are 10 proven subject lines tailored for different industries, along with actionable tips to maximise your open rates.

Tips for Crafting Winning Subject Lines

1. Keep It Short and Sweet

Most email clients cut off subject lines after 40–60 characters. Make sure your key message fits within that limit.

2. Personalise Where Possible

Subject lines with personalisation (e.g., the recipient’s name or location) perform 26% better than generic ones.

3. Test, Test, Test

Run A/B tests to see which styles, tones, and lengths resonate most with your audience.

4. Leverage Curiosity

Subject lines that hint at exclusive content or leave something to the imagination often lead to higher opens.

5. Add Numbers

Numbers signal concrete, actionable content and tend to attract more attention. For example, “5 Quick Ways to Improve Your Morning Routine.”

6. Use Power Words

Incorporate emotionally charged words like “exclusive,” “proven,” “guaranteed,” or “free.”
