FOMO-packed email subject lines

Here's the thing about scarcity: people hate missing out on stuff. When someone thinks an opportunity might disappear, they act faster than usual. These FOMO-driven subject lines work because they tap into that fear.

  1. Last chance: 50% off ends tonight
  2. Only 3 spots left for tomorrow
  3. Final hours: Your cart expires soon
  4. Exclusive access ends at midnight
  5. Limited time: Double rewards today
  6. Almost gone: Reserve your seat
  7. Ending soon: Free shipping weekend
  8. Quick: Sale ends in 2 hours
  9. Final call: Registration closes tomorrow
  10. Hurry: Only 5 left in stock

You can make these even better by using Superhuman's Send Later feature to time them perfectly when people are most likely to check email.

Curiosity-sparking subject lines

Your brain hates incomplete information. When you see a subject line that starts something but doesn't finish it, you literally can't help wanting to know what comes next. These attention-grabbing subject lines create that irresistible curiosity gap.

  1. What happened next will surprise you...
  2. The secret your competitor doesn't want out
  3. Why everyone's talking about this?
  4. You won't believe what we found
  5. The mistake 90% of teams make
  6. Something unusual happened yesterday...
  7. Can you guess what this is?
  8. The results are in and...
  9. This changes everything we thought
  10. Wait until you see this

Pro tip: add preview text that gives just enough detail to make people even more curious, but don't give away the whole story.

Benefit-focused subject lines

People open emails when they know exactly what they'll get out of it. Skip the clever wordplay and tell them the benefit upfront. These headlines work because they promise something specific and valuable.

  1. Grow revenue 30% in 90 days
  2. Cut costs without sacrificing quality
  3. Double your leads this quarter
  4. Save 10 hours every week

  10. Streamline operations starting now

Notice how these use action words like boost, save, cut, double. They create momentum and make people want to click immediately.

Personalization and name-drop lines

Personalized subject lines work better because they feel like real conversations instead of mass emails. Use what you know about the person you're emailing to create targeted messaging.

The key here is using specific details that show you actually pay attention to what they're doing, not just inserting their first name.

Urgency and scarcity lines

Real deadlines create different urgency than general FOMO. These work because they give people a specific reason to act right now instead of later.
