A/B tested subject lines for 30 days, one word changed everything

Ran my client's email campaign last month, tried 40 subject lines across 5 sends. Adding a number like "3 tips" beat any question or emoji, got 22% open rate vs my usual 11%. Anyone else seeing numbers outperform curiosity hooks?

Honestly that's such a relief to hear someone else getting real numbers from this. I've been seeing the same thing with my clients, numbers in subject lines just crush questions every time. I switched one client from a curiosity hook to "7 ways to fix your morning routine" and it doubled their opens in a week. It's wild how such a small tweak makes people feel like they're getting something concrete instead of a tease.
