Auto-match your Substack with creators your audience already loves
ReachPair detects audience overlap between newsletters using engagement patterns, then automates the cross-promo email — so both creators grow without cold outreach or spreadsheets.
One-time early-access payment. Checkout is hosted securely by Stripe.
How it works
Audience overlap detection
Analyzes engagement patterns across personal finance, side hustles, crypto, and real-estate newsletters to find creators whose readers overlap with yours.
Automated cross-promo emails
Once a match is found, templated cross-promo emails go out to both creators — no awkward cold DMs, no back-and-forth scheduling.
Complementary niche matching
We pair personal-finance writers with side-hustle, crypto, and real-estate creators so each swap reaches a fresh but highly relevant audience.
Grow without ad spend
Newsletter swaps consistently drive the highest-quality subscribers. ReachPair makes them effortless and automatic.

Prefer to wait for your invite?
Join the waitlist if you want updates before paying. We're still onboarding newsletters in batches and can reach out when a new spot opens.
