Grow your newsletter without ads. Swap subscribers with newsletters just like yours.
Grow your newsletter by 50–200 subscribers/month through targeted swaps — no ads, no algorithms.
Subroute auto-matches micro-newsletter creators in the same niche for subscriber swaps — collaborative cross-promotion that actually works.
How it works
Three steps to collaborative growth.
Step 01
Connect your newsletter
Link your Substack, Beehiiv, or any newsletter platform. Tell us your niche, audience size, and what makes your content unique.
Step 02
Get matched with similar niches
Our matching engine pairs you with complementary newsletters — same niche, similar audience size, high compatibility. You approve every match.
Step 03
Swap shoutouts and grow together
Coordinate a shoutout swap. You feature them, they feature you. Real readers, real growth — no ad spend, no bots.
