Preheader Text Generator — Stop wasting preview text: summarize your email for 6 preheader options in 5 tones that complement your subject line instead of repeating it. Boost opens now!

Preheaders are assembled from a bundled library of 18 base templates combined with 5 deterministic tone extenders — no AI, no network. Every variant is measured in user-perceived characters and kept between 40 and 100: short drafts are padded with a tone extender, long ones are trimmed at a word boundary. Variants that would restate more than half of your subject's key words are skipped, so the preheader complements the subject instead of echoing it.
