You spend an hour crafting the perfect email. You hit send to your list. Then you check the stats: 8% open rate.
The problem wasn’t your email. It was the subject line nobody bothered to open.
What Kills Open Rates
Generic subject lines. “Newsletter – March 2025.” “Update from [Company Name].” “You don’t want to miss this!”
Your recipient gets 100 emails a day. Give them a reason to care about yours.
What Actually Works
Specificity wins.
“How we cut our client’s lead cost by 40%” beats “Marketing tips inside.”
“The one thing breaking your website’s mobile speed” beats “Website optimization advice.”
People open emails that promise a specific, useful answer to a problem they have.
The Curiosity Gap
The best subject lines create just enough curiosity without being clickbait.
“The follow-up mistake costing you deals” makes you want to know what the mistake is.
“You won’t believe what happened next” makes you roll your eyes and delete.
Test The Obvious Stuff
Does adding the person’s name help? Sometimes. Does using emojis work? Depends on your audience.
The only way to know is to test. Send version A to half your list, version B to the other half. See what performs better. Do that consistently and your open rates will climb.
The Real Secret
Write subject lines for one person, not a crowd. Imagine you’re texting a colleague who needs help with something specific.
That’s the energy that gets emails opened. Everything else is just noise in an already noisy inbox.
