Why Your Email Subject Line Matters More Than the Email Itself

You could write the juiciest email in the underworld, but if your subject line sucks, it’s DOA—dead on arrival. Subject lines are the gatekeepers. They’re what decides whether your email gets opened or left to rot in the inbox graveyard. Let’s talk about why subject lines matter more than the email itself and how to write ones that actually get clicks.

1. Keep It Short and Sweet

Most people check email on their phones. Subject lines over 50 characters get cut off like a decapitated vampire. Keep it punchy. Example: “Your next biz spell is waiting 🪄” works better than “Here is our comprehensive breakdown of all the new updates to our store.”

2. Create Curiosity

Make people itch to know more. Questions and teasers work wonders. Example: “Want to triple your sales?” or “This spooky mistake is costing you money.” Just don’t lie—clickbait kills trust.

3. Personalize It

Emails with personalized subject lines are 26% more likely to be opened (Campaign Monitor). Even just adding a first name—“Emily, ready to grow your biz?”—feels warmer and more inviting.

4. Test Your Spells

Use A/B testing to see what works for your audience. Most email tools let you test two subject lines. Maybe your list loves sass. Maybe they love emojis. Data will tell you.

5. Pair It With a Killer Preview Text

Preview text is the sidekick. If the subject line is the jump scare, the preview text is the creepy whisper that pulls them in. Write them together for maximum impact.

Closing the Coffin

Your subject line is your one shot to get that email opened. Nail it with curiosity, personalization, and brevity, and your carefully crafted email won’t end up six feet under.
