Why this site exists
Newsletter advice gets vague quickly. A lot of it sounds good until you are the person staring at a blank send screen, a messy subscriber CSV, or a tool bill that has started to creep up.
Newsletter Supply is where I organise the answers I wish were easier to find: which newsletter platform fits which stage, how to set up the first growth loops, when monetisation actually makes sense, and what to check before trusting a tool with your list.
Most of the site is built around three jobs: launch, grow, and monetise. Some pages are tactical tutorials. Some are tool reviews. Some are comparisons for the moment when you are stuck between two decent options and need a practical answer.
When something comes from firsthand operator experience, I say so. When a claim depends on a platform feature, pricing page, migration guide, or help doc, I link to the source. The goal is not to sound certain about everything. The goal is to help you make better newsletter decisions with less guesswork.
