Boosting Your Email Open Rates:
Step 1: Grab the exact email you sent out before, but give it a brand-new, eye-catching subject line. 📝
Step 2: One week later, send it out again—but only to the non-openers from the original email.
Boom! You’re likely to see a 30%+ increase in opens. Easy win, right?
