Imagine spending hours crafting the perfect email—full of valuable tips, must-have resources, and a limited-time offer—only for it to land in your audience’s inbox and never get opened. Unfortunately, that is often the case, but it doesn’t have to be.

Your subject line is the first (and sometimes only) chance you have to grab your audience’s attention. In just a few seconds, a teacher scanning their inbox will decide: open, ignore, or delete. And if your subject line doesn’t spark curiosity, create urgency, or promise value, your email might never see the light of day.

If you’re serious about selling more on TpT and building an engaged audience, mastering the art of subject lines is non-negotiable. Let’s dive into what works, what doesn’t, and how you can write subject lines that practically demand to be opened.

Here are some subject line strategies you can use to get higher open rates.

1. Ask a Thought-Provoking Question

  • “Are you making this classroom mistake?”
  • “What if your students LOVED word problems?”
  • “How do you handle fast finishers?”

2. Create a Sense of Urgency or FOMO (Fear of Missing Out)

  • “Only 2 days left to grab this classroom freebie!”
  • “Don’t start your next unit without this tip!”
  • “Stop struggling with behavior issues—try this today!”

3. Use Personal Experience or a Relatable Story

  • “I was making this grading mistake for years…”
  • “The moment I realized my students weren’t really learning…”
  • “What I wish I knew my first year teaching”

4. Highlight a Quick Win or Easy Fix

  • “A simple trick to get students engaged instantly”
  • “The easiest way to improve classroom management”
  • “Try this 5-minute activity for instant student focus”

5. Use a “You vs. Them” Comparison

  • “Great teachers do this—do you?”
  • “Why some teachers get better behavior results”
  • “Is your classroom running YOU?”

6. Make a Bold or Unexpected Statement

  • “Why I stopped using worksheets (and what I do instead)”
  • “You’re grading too much—here’s what to do instead”
  • “The #1 thing that saved my sanity this year”

7. Play on Emotions (Joy, Frustration, Relief, etc.)

  • “The lesson that made my students’ eyes light up!”
  • “This email will save you HOURS of planning time”
  • “I was SO frustrated—until I tried this”

8. Use a Teacher Meme or Pop Culture Reference

  • “When you realize it’s Monday morning…😩”
  • “The Beyoncé approach to classroom management”
  • “If teaching were like The Hunger Games…”

9. Break the Pattern with an Unusual Subject Line

  • “Well, that was a disaster…”
  • “I did the math, and it’s NOT adding up”
  • “Oops… I almost forgot to tell you this!”

10. Tease an Exclusive or Insider Tip

  • “My secret to getting students to actually do their work”
  • “What no one tells you about lesson planning”
  • “This one hack changed how I teach fractions”

11. Create Curiosity

  • You won’t believe what my students did when…
  • This one tweak changed my classroom management
