Paste your subject line and get an instant score based on length, spam-trigger words, personalisation, and urgency.
Scores a subject line before you send it — length, clarity, spam triggers, and open-rate signals. Paste a subject line in; get a score and specific fixes out.
Bring the subject line of your next campaign, or your last one. Test a couple of variants against each other — the comparison is usually more revealing than any single score.
The subject line decides whether the rest of your email exists at all. A weak one can halve your open rate, which halves everything downstream — clicks, bookings, sales — for the same effort and cost.
Our Email Marketing product writes, tests and sends your campaigns for you, with every send measured and the next one improved by it.
