What is Substack?

Substack lets authors, podcasters, and writers publish content like newsletters, e-books, blog posts, and podcast episodes to sell to subscribers. This content gets delivered right to subscribers’ inboxes through Substack’s marketing automations and solutions.

Substack creates a way for these creators to build their audience and monetize their offerings with a proprietary payment plan. They also create a storefront where readers can browse through the offerings and select publishers that match their interests.
