How it works

Auto-swap recommendations with your matches. Every subscriber you drive earns you a Stripe payout. Simple.
Why SubPact
Random cross-promos waste your readers' trust. Paid ads drain your budget. SubPact gives you targeted, automated growth with real revenue.
Substack ads cost $2–5 per subscriber. SubPact cross-promos average $0.20 — and they're warmer leads.
No more random cross-promos with unrelated newsletters. We pair you with writers your readers will actually love.
Set it and forget it. SubPact handles matching, recommendation placement, tracking, and payments automatically.
Earn actual Stripe payouts for every subscriber you drive. Track everything in your dashboard in real time.
Join the waitlist and be first to access SubPact when we launch. Early writers get priority matching and lower fees.
