# Substack Sign up

We document the step-by-step **Sign Up** flow from Substack. The flow contains **6 steps** and was updated in **February 2026**. Lazyweb is a design research library for comparing product flows across apps.

## Captured screens

We show **5 of 6 screens** from the Substack sign-up flow. The sixth screen is not included in the public preview; the complete flow is available through [free Lazyweb signup](https://www.lazyweb.com/product).

1. Welcome to Substack, with **Sign up** and **Log in** actions.
2. Email entry: “What’s your email?”
3. Inbox verification: “Check your inbox,” with a verification-code interface and options to open email or resend email.
4. Profile creation: “Create a profile,” including a name field and social-account options.
5. Username selection: “Pick a username,” with an availability indicator and a Continue action.
