Vrtcl automatically matches productivity and ADHD writers with newsletters their readers actually want — and swaps subscribers based on real engagement data, not vibes.
How it works
Link your Substack in 30 seconds. We pull your engagement data — open rates, click-throughs, subscriber behavior. No exports. No spreadsheets.
Our algorithm scores your newsletter and finds compatible writers in the productivity and ADHD space. Match quality is based on audience overlap and engagement benchmarks — not just niche or size.
Confirm the match, customize the recommended swap copy, and publish. Both newsletters promote each other to their highest-engagement segments. Watch the subscribers come in. Repeat.
Features
Every swap is based on your readers' actual open rates, click rates, and reading habits — not follower counts. A shoutout to 10,000 half-asleep subscribers is worth less than one to 500 people who open everything. Vrtcl optimizes for the latter.
Connect your Substack, set your preferences, and Vrtcl handles the scheduling, copy suggestions, and tracking. No DM negotiations. No awkward cold pitches. No spreadsheet of who owes you one. You're a writer, not a partnership manager.
See which swaps drove subscribers, how those subscribers engage compared to your average, and which partner newsletters send you your best readers. Cut what doesn't work. Double down on what does. Most newsletter growth is a black box. Vrtcl gives you a window.
