Everything a newsletter swap needs. Nothing it doesn't.
Auto-Matching
Our algorithm pairs you with newsletters at your exact open-rate level — no cold outreach, no negotiation, no awkward emails.
Open-Rate Compatibility
Only swap with writers whose audiences actually convert. Compatibility scoring ensures every swap moves the needle.
Built-In Rev-Share
Every subscriber you send earns you a cut of future revenue. Your best issues keep paying you long after you write them.
Three steps to your next 1,000 subscribers.
Connect your newsletter
Link your Beehiiv, Substack, or ConvertKit account. We analyze your open rates and audience profile in minutes.
Get matched automatically
Syndlab finds your compatibility tier and matches you with 2-3 newsletters whose audiences overlap with yours — without cannibalizing growth.
Swap and earn
Your best-performing issues go out to matched audiences. Theirs come to yours. Subscribers flow both ways, rev-share handles the rest.
Your best issue deserves a bigger audience.
