// HOW_MATCHING_WORKS
Subloom matches newsletters by niche, audience size, and engagement — so every swap actually moves the needle for both sides.
// MATCHING_ALGORITHM
We tag every newsletter by community: indie hacker, solopreneur, crypto, fintech, Europe, no-code, SaaS, bootstrapper, and more. We only match you with newsletters your audience actually cares about.
We keep swaps fair by only matching newsletters within a ~2x audience size ratio. A 500-subscriber newsletter matches with 250–1,000 range partners — not with someone 10x their size.
Subscriber count alone doesn't tell the whole story. We factor in open rates, click-through rates, and list growth velocity to ensure you're paired with an active, engaged audience.
