Bulletter connects indie finance, crypto, and trading newsletter writers for automated list swaps — reach aligned subscribers, measure audience fit before you commit, and earn Stripe payouts when partners rent your list.
No spam. Invite-only beta for Substack & beehiiv writers.
Match with complementary newsletters and automatically cross-promote to each other's audiences. Set your criteria, approve the match, and Bulletter handles the coordination — no spreadsheets, no cold DMs.
Before any swap, see exactly how much your readers overlap. Bulletter scores compatibility across topics, engagement level, and subscriber demographics so every swap is worth it.
When another writer wants to rent your list, you set the price and terms. Bulletter escrows the payment and releases it after the send — straight to your Stripe account. Your list, your rates, your rules.
For writers building momentum.
For serious growth and monetization.
Link your Substack or beehiiv account. Bulletter imports your subscriber count and topic tags.

Browse curated matches with full overlap scores. Accept, decline, or counter with different terms.
Execute swaps with one click. For rentals, Bulletter escrows payment and deposits to your Stripe automatically.
“I grew my trading newsletter from 8K to 22K subscribers in 3 months purely through Bulletter swaps. The audience overlap scoring is what made the difference — I only swapped with newsletters that had under 15% overlap.”
