How this list is built
A disposable email domain is a domain that hands out temporary inbox addresses to anyone, with no account and no lasting owner, so the address stops working or becomes public after a short time.
Where it comes from. We compile the list from public blocklist data, remove duplicates, and write one file that the checker reads. Nothing is added by hand.
How often it updates. Once a day, on a schedule. A newly reported domain shows up here within a day, and a domain that drops out of the data disappears just as fast.
What counts as disposable. A domain lands on the list when it belongs to a service that gives out throwaway inboxes, including the many alias domains that a single temporary mail site rotates through.
Limits. A list like this is never complete or perfect. New providers appear faster than any list tracks them, so a domain that is missing here can still be disposable. In the other direction, a real mail provider can be listed by mistake. If that is your domain, email hello@eml.monster and we will review it and remove it.
Indexed checks

Want a private address that never gets blocked?
Disposable addresses get blocked everywhere because they are not tied to a real person. Email Monster gives you a permanent private alias like amazon@yourname.eml.monster that works on every website, hides your real address, and lets you switch off any sender with one click.
