When you use a temporary email, the service creates a new, disposable inbox for you. This inbox exists for a limited time and is completely separate from your personal email. Websites send verification or confirmation links to this temporary address, and you can read those messages on the service's page. After a set period of hours or days, the temporary email address and its contents are automatically deleted, so any future emails sent to that old address will bounce back.
