Aim for ≤50 characters. Preview text should add new information, not repeat the subject. Never fake “Re:”/“Fwd:” or urgency.

5 rules that keep you shipping

  1. Lock next week’s title by Friday.
  2. Never start two new issues in the same day.
  3. If the draft is under 400 words by send-minus-24h, cut scope and ship a short issue.
  4. One primary CTA per issue. Two max.
  5. Log KPIs within 24h of send.
