Disposable Email Checker

Enter a domain and find out whether it belongs to a disposable email provider. Free, no signup — and yes, we mark our own domains too.

You can paste a full address (name@example.com) — only the domain is used, and nothing is stored.

These verdicts are generated from the same data the checker uses, so they can never drift out of sync with it. The description explains what each service is; the verdict reflects what the blocklists say about it.

Why there are two levels instead of yes or no

Most free checkers answer with a flat true or false. That hides the thing you actually need to know: how sure the answer is. We use two lists with different editorial standards, and tell you which one matched.

Listed

The domain is in a conservatively curated blocklist — entries are reviewed, and false positives are rare. If you are going to block or flag an address automatically, this is the level to act on.

Possibly

The domain is only in the broader list, which favours coverage over precision. Useful as one signal among several. Blocking on this level alone will occasionally reject a legitimate user.

Not listed

Neither list has it. Note what this does and does not mean: no blocklist is ever complete, and a brand-new disposable domain will pass this check for a while.

A blocklist match is evidence, not proof. For anything consequential, combine it with signals you control — MX records, domain age, account behaviour, or a confirmation email.

Alias services are not the same as disposable email

Services like SimpleLogin, DuckDuckGo Email Protection, and Gmail's own plus-addressing give you an address that forwards to a mailbox you keep. The address is disposable; the mailbox behind it is not. The person still reads their mail, still replies, and still recovers their account later.

Blocklists disagree about how to treat them, so you may see an alias domain flagged. That is worth knowing before you block one: rejecting alias users turns away privacy-conscious people who are otherwise perfectly real customers. A disposable inbox is abandoned in minutes; an alias can outlive the account it was created for.

The data contradicts itself in ways worth seeing. addy.io is listed, while anonaddy.com — the same company's older domain — is not. relay.firefox.com is listed even though Firefox Relay actually hands out addresses on mozmail.com, which is not listed at all. Both of those flags land in the 'possibly' tier rather than 'listed', which is precisely what that tier exists for.

We list our own domains as disposable

MoeMail is a disposable email service. Our domains do exactly what the blocklists describe, so the honest answer is that they belong on those lists — and this checker says so.

We could have quietly excluded ourselves. We did not, for a plain reason: anyone can test their own domain against a checker in five seconds, and a tool caught hiding its owner is worth nothing. If you run a site and want to keep throwaway signups out, you should be able to use this tool to block us too.

How sites actually detect disposable email

A blocklist lookup like this one is only the first layer. Real systems stack several checks: matching the domain against public and commercial lists, resolving MX records to see whether mail is even accepted, looking at how recently the domain was registered, and watching what the account does after signup.

That is also why an address sometimes gets rejected even though it is not on any list — and why a disposable address occasionally sails through. If you want the longer version, we wrote about it separately.

Why websites block disposable email

Where the data comes from

The checker queries two open blocklists maintained by the community. The second is an aggregator, so the repositories feeding it are credited below as well — every one of them linked back to its source. We rebuild our copy from upstream rather than editing entries by hand, so what you get here matches what the maintainers publish.

This is not an exhaustive account of the data. The aggregator also scrapes throwaway-mail websites, which have no repository or licence to name. Its source is published, so you can audit the full set yourself: generator.py

Download the list

The merged, deduplicated list is available as a plain text file — one domain per line, no key, no rate limit. Use it in your own project.

disposable-domains.txt

Neither list claims to be current or complete, and the maintainers say so plainly. Domains change hands, services shut down, and new ones appear every day. Treat what you get here as a community-maintained snapshot rather than a live authority.

Questions

No. Gmail is Google's consumer mail service and does not appear in disposable blocklists. Addresses on it belong to accounts that persist, so they are not throwaway addresses. Gmail's plus-addressing (name+tag@gmail.com) creates a disposable-looking variant, but the mail still lands in the same permanent inbox.

No. The lookup happens against a list compiled into the site at build time, and the domain you enter is not written to any log or database of ours.

Yes. Paste the whole address and only the part after the @ is used. The local part is discarded immediately and never leaves the request.

Blocklists lag reality. New disposable domains launch constantly and take time to be reported and reviewed. A not-listed result means no list has it yet — not that the domain is trustworthy.

Block on the 'listed' level if you want throwaway signups gone. Be more careful with 'possibly' — that list trades precision for coverage, and blocking on it alone will occasionally turn away a real customer. Alias-forwarding services deserve particular care.

We rebuild it from upstream periodically. Because it ships with the site rather than being fetched at request time, the list you are querying is the one from our most recent deploy.

Need a disposable address yourself?

MoeMail creates temporary mailboxes that expire on your schedule — 10 minutes to 3 days — and deletes the mail with them.
