Email Subject Line Generator

Tell us your campaign goal — get 10 high-open-rate subject lines using proven psychological triggers, plus 3 preheader options.

The angle framework: each generated line is written against one of three tested angles — urgency (deadline/scarcity), curiosity (open loop), or benefit (clear value stated upfront). Mixing angles across a send and A/B testing which one your list responds to matters more than any single "perfect" line.

Limitations: open-rate impact varies by list, sender reputation, and inbox provider — treat these as strong starting drafts to test, not guaranteed performance.
