On using a newsletter platform's built-in audience network for brand reach

The writer of the Marketing Ideas newsletter at Marketing Ideas raises how a company publication on Substack can draw readers through the platform's built-in recommendation network rather than through search or ads. A reader can take from it that recommendations work like a referral loop: trading placements with firms whose customers overlap, checking audience stats for shared readers, and asking sponsorship partners for a mention all cost little. It suits B2B startups with engineers or founders who can be interviewed and published under their own names. The evidence rests on one newsletter's summer traffic plus a handful of company examples, mostly tech and well-known brands, so a company without an audience of builders or a recognisable name may see far less from the recommendation mechanism.
