Readflow matches indie newsletter writers who want to grow — and lets you trade engaged subscribers with complementary newsletters. Automated matching. Verified audiences. Fair payments for unequal swaps.
HOW IT WORKS
STEP 01
Link your Substack in 30 seconds. We verify your audience size and engagement rate.
STEP 02
Our engine surfaces writers whose audiences overlap with yours but read different content.
STEP 03
Approve the match, confirm the terms, and watch engaged subscribers appear in your list.
WHY READFLOW
Our algorithm finds complementary newsletters in your niche — same audience size, different angle. No cold outreach required.
Browser automation checks open rates, engagement, and real subscriber counts before any swap is approved. No inflated numbers.
Swapping 800 subs for 1,200? We calculate a fair settlement automatically, processed securely via Stripe. Growth without friction.
The idea of doing cold outreach to find newsletter collaboration partners always killed my momentum. With Readflow it's like having a matchmaker who already knows exactly who your readers want to hear from next.
