What does EmailSubjectGrader do?
EmailSubjectGrader gives any email subject line an instant A–F grade and tells you what to change before you send. It checks length, flags words that tend to look spammy, notes power words, questions and numbers, and explains each point in plain language, so you learn the pattern, not just a score. Paste in a few variants to compare them side by side before an A/B test. It’s free, needs no account and runs in the browser.
