For Substack writers
Grow your Substack through
better cross-promotions.
Syndicate helps you find relevant newsletter partners, coordinate the swap, and get ready-to-send promo copy so you can grow without cold outreach, awkward asks, or another growth tool to manage.
Apply once, share your newsletter details, and we will reach out when there is a strong cross-promotion fit.
Why Syndicate
The right partners. Fewer excuses not to grow.
Find partners your readers will actually care about
Stop guessing which newsletters are worth approaching. Syndicate matches you with Substack writers in a similar niche and size band, so your cross-promotions feel aligned instead of random.
Skip the back-and-forth that kills the swap
Most newsletter partnerships die in DMs and email threads. Syndicate handles the intro, confirms mutual interest, and gives both sides a clear send window so the promotion actually happens.
Launch growth experiments without buying ads
If you want more subscribers but you are not ready for sponsorship budgets or paid acquisition, cross-promotions are a simpler next step. Syndicate helps you test a focused growth channel using the audience you already have.
How It Works
One simple workflow from match to send.
No dashboards to learn. No DMs to send. Just a clear path from profile to published swap.

FAQ
Common questions
Who is Syndicate for?+
Syndicate is for independent Substack writers who already publish consistently and want audience growth through relevant newsletter partnerships.
Do I need a large list to use this?+
No. The best fit is usually a writer with enough traction to be a credible partner, but not so much scale that manual outreach is easy to justify. A healthy, engaged niche audience matters more than having a massive list.
How is this different from Substack recommendations?+
Substack recommendations are useful, but they mostly live inside the platform's native flow. Syndicate is built around actively matching partners and helping both sides complete a dedicated cross-promotion swap.
Is this a paid ads product?+
No. Syndicate is for writers who want growth through partnerships, not by managing ad spend or buying subscribers.
How much work do I have to do?+
Very little. You provide your newsletter details, approve the match, and send the promo in your issue. Syndicate reduces the research and coordination work that usually slows everything down.
Will I get promo copy?+
Yes. Each match includes suggested copy so you are not starting from a blank page.
