For Personal Finance Substack Writers

Grow your newsletter
without buying ads.

Peer Lettr matches indie personal-finance writers for subscriber swaps — pairing you with newsletters whose audiences are 70%+ aligned with yours, then handling the emails and tracking so every trade is fair.

Free early access · No credit card

Built for the way writers actually grow.

Precision Audience Matching

Our algorithm finds writers whose subscriber base overlaps 70%+ with yours — "side hustles" meets "crypto trading," not random cold pitches. Every swap reaches readers already primed for your niche.

Fair-Trade Performance Tracking

Live dashboards show exactly how many new subscribers each writer delivered. If numbers slip, the system rebalances automatically — so every trade stays honest.
