For newsletters under 5k subscribers

Automate newsletter list swaps and split referral revenue when paid readers convert.

Lettrix helps indie hacking letters, solopreneur Twitter digests, and crypto briefs find adjacent partners, trade placements, track referrals, and share Stripe upside without messy spreadsheets or one-off sponsorship deals.

Stripe checkout opens in a new tab. Lettrix Pro is live now at $19 for early creators.

  • Match with adjacent niche newsletters instead of cold-pitching random audiences.
  • Attribute referred readers from list swap to paid conversion.
  • Automatically share Stripe revenue so both creators get paid.
  • Stay useful for micro-creators before ads, sales teams, or sponsorship ops exist.

This opens a prefilled email for creators who want a manual onboarding conversation before buying.
