From a recent report 👇

Imagine building a million-dollar business by simply organizing other people’s emails. That’s exactly what Chaz Yoon did with Milled.com

The site is a big database of e-commerce emails.

Marketers use it to see how big brands are doing email marketing 👀

Chaz started it in 2012 and it has become…

A bootstrapped, one-person operation that generates $768K-$1.2M annually

It was initially monetized with affiliate links, but now mainly earns via subscriptions for pro features 💰

Clearly Chaz got in early on this idea and that was a big part of his success.

And he’s been so successful that I’m thinking a niche version of this could also do well 🤔

How about an email marketing database for…

  • SaaS companies
  • Nonprofits
  • Health and wellness brands
