What it does

Structure and write email newsletter editions

Best for

Email newsletters where subject line and format consistency drive both open rates and habit—when you want predictable engagement metrics.

Inputs
  • · topic/niche and target audience
  • · frequency (weekly/biweekly/monthly)
  • · content type mix (curated, essays, tips, news)
  • · subscriber count and current open rates
  • · monetization model
Outputs
  • · subject line (6-10 words, mobile-optimized)
  • · newsletter edition with consistent section structure
  • · preview text optimized for email clients
  • · growth tactics for subscriber acquisition
  • · A/B test recommendations
Requires
  • · Email platform (Substack, Mailchimp, ConvertKit, etc.)
Preconditions
  • · Email list or signup mechanism in place
  • · Consistent publishing schedule decided
Failure modes
  • · Generic subject lines → 10% open rate (vs. 35%+ for curiosity-driven)
  • · Newsletter = company news → nobody cares
  • · Too many links per section → dilutes clicks
  • · No consistent format → readers don't build habit
  • · No growth strategy → stagnant subscriber base
Trust signals
  • · Subject line formulas with examples (curiosity gap, numbered value, question, personal)
  • · Mobile-first optimization (6-10 words = 40-50 characters)
  • · Preview text strategy (complements vs. repeats subject)
  • · A/B testing guidance by subject formula type
