I built this because I was tired of wasting time second-guessing subject lines that barely got clicks. Email is still the most effective marketing channel, but if your subject line flops, everything inside gets ignored. I wanted a fast, no-fluff way to know if a line works and how to fix it on the spot. That’s what this tool does. It’s simple, but it solves a real problem. Try it out and tell me what sucks... I can take it.

This is a great idea. Id be interested to know how the score is determined. I spend lots of time back and forth being indecisive on the subject so definitely a time saver and confidence booster.
