As a consumer there are several different sorts of email address that are described as “disposable” or “temporary”. Some of them are what we might call tagged addresses – addresses that are unique, created to be given to a specific vendor. If it’s misused by the vendor, or if it’s leaked to spammers, then the address can be disabled, either by rejecting or by silently discarding mail sent to it. Others are created for a specific use, and will only be briefly valid, either for a single email or for a short period of time (ten minutes, an hour, something like that). They typically don’t have any connection to a users “real” email address, and are just accessed via a web page. A user might use this when they’re being required to give an email address to access some sort of service but there’s no ongoing use of that email
