Product-Market Fit in Email Marketing

DIRECT ANSWER

Product-market fit is the state in which a product satisfies strong, repeatable demand from a well-defined market segment.

What product-market fit means in Email Marketing

The most widely used quantitative signal is the Sean Ellis test: survey active users and ask how disappointed they would be if the product no longer existed. A 'very disappointed' rate above 40% correlates strongly with durable growth. Below 25% is a clear signal to iterate. Retention curves that flatten rather than drain to zero are a complementary structural sign — if a cohort stabilizes at 20–30% weekly retention after the first month, the product is holding a real audience.
