SUBSTACK IS A $0 CHEAT CODE FOR YOUR BRAND

Summary from the TLDR Marketing newsletter

Substack can send a newsletter roughly 50X more subscribers than Google, since every signup surfaces a few newsletters the writer recommends. Companies are tapping that loop with behind-the-scenes posts from the people building the product. PostHog recommends 10 engineering newsletters that all recommend it back, while Ramp gets a recommendation from TBPN's Substack as part of its sponsorship. Substack's audience stats rank which newsletters already share a brand's readers, pointing to the best swap partners.
