How it works
Three steps from signup to your first subscriber gain payout.
Join & categorize
Sign up and tag your newsletter's niche — solopreneur tips, indie gamedev, crypto alpha, whatever you publish.
Get matched monthly
Syndli pairs you with newsletters in overlapping categories. Each match is curated for audience fit, not just follower count.
Swap lists, earn payouts
Your matched newsletters recommend each other to their lists. At month's end, net subscriber gains hit your Stripe account.
Curated, not random
Matches are based on content category overlap, not follower count. Your readers actually want what your match writes.
Stripe payouts for gains
Every net subscriber you bring in earns you money. Grow your list AND your revenue at the same time.
Opt-in, privacy-first
Subscribers choose to hear from matched newsletters. No list selling, no shady data deals.
