Lead Magnet

A lead magnet is a free, immediately useful resource — a cheatsheet, template, checklist, mini-course, or tool — that you give away in exchange for someone’s email address. It converts anonymous visitors into subscribers you can market to over time.

Why it matters for developers

For developers building a newsletter-first business, the lead magnet is the entry point to the entire funnel. A relevant, high-value magnet can lift email opt-in rates several times over a generic "subscribe" box.
