Niche newsletter guest post for zero-cost leads
Write a guest post for a small, niche-relevant newsletter (1K–10K subscribers) to reach a highly engaged audience at zero cost.
Why this can grow a startup
Small niche newsletters have some of the most engaged audiences on the internet because subscribers opted in for a specific topic. The cost-per-lead from a well-placed guest post in a 5K-subscriber newsletter can be lower than any paid channel. Newsletter owners are often hungry for quality content and sponsors, making partnerships easy to arrange.
