Read mail delivered to an inbox from create_inbox — e.g. to pull a verification code or confirmation link out of a signup email. Returns newest-first. Mail usually lands within seconds; if the response is empty, wait a few seconds and call again (there is no blocking wait). Extract the code or link yourself and continue the flow in the browser. Pass format="html" when you are AUDITING the email rather than reading a code out of it: the default text view flattens away the layout, typography and branding, which is exactly what an email audit is judging.
