Learn how BooleanSMTP works
Three short, interactive lessons — how a WordPress email travels, which mailer to pick, and why a sent test sometimes never arrives.
These lessons explain what happens behind the settings screens. Each one takes a few minutes, has an interactive diagram you can step through at your own pace, and ends with two or three questions. Your progress is kept in this browser only.
