For Substack solopreneurs
Grow your Substack by trading your best readers — not buying ads
PassAlong lets indie newsletter writers swap curated, high-engagement subscriber segments with each other. Trade 500 of your most active readers with another newsletter's audience — in a single transaction, with full transparency on open rates.
How it works
Three steps to your next
100 engaged subscribers
Connect your Substack
Link your Substack account. PassAlong reads your subscriber engagement data — open rates, click-through rates, reply rates — to identify your top-tier readers.
Choose a swap partner
Browse the marketplace of verified solopreneur newsletters in the business advice niche. Filter by audience size, niche alignment, and average engagement score.
Swap your top readers
Propose a segment swap — e.g. "500 of my most engaged readers for 500 of yours." Both parties confirm, PassAlong handles the migration, and your list grows with warm readers who already love this content.
Why PassAlong
Ads get you clicks. Swaps get you readers.
When a subscriber moves from one solopreneur newsletter to yours, they're already primed for business advice content. They've chosen this niche deliberately. Compare that to a cold ad impression to someone scrolling past.
PassAlong is built on reciprocity — every swap is a two-sided trade of equal engagement value. Nobody sends you their disengaged ghosts and keeps their best readers.
