If you've ever tried to test your own signup flow, provision a demo account, or sign up for a vendor's API on behalf of your one-person company, you've hit the same wall every solo founder hits: the form submits fine, and then the service says "check your email to verify your account." Now a human has to open an inbox, find the code or the link, and come back to finish the job. That single step is why so many "fully automated" onboarding tests still have a person babysitting them.
You don't need to be an engineer to fix this. This guide shows how to build a registration bot with Claude Code — the AI coding agent — where Playwright handles the browser and email verification is solved by a temporary inbox the bot owns. You describe what you want in plain English; Claude Code writes and runs the Playwright automation and the email lookups for you. No prior coding experience required, no manual "please check your inbox" step left in the loop.
Why email verification breaks no-code registration bots
Most no-code and low-code automation tools are genuinely good at the mechanical parts of signing up for something: filling a name field, generating a password, clicking submit. Where they consistently fall apart is the moment the target service says "we sent you an email."
