Catch throwaway inboxes before they become accounts.
Attrelix checks each signup address against around 98,000 known disposable domains, refreshed every day, and tests whether the domain can receive mail at all.
One script tag and one server call. No card to start.
Why a static blocklist is not enough
New disposable domains appear every day, and a list copied into your code goes stale within weeks. Many temporary services also rotate domains to dodge blocklists.
And an inbox is only one signal. A real Gmail address can still be the fifth account of the same person.
What Attrelix checks on every address
Disposable domains
Merged public lists refreshed daily, with the date each domain was first seen and which lists include it.
Can it receive mail?
Domains without a working mail server are flagged, since nobody can confirm an account there.
Aliases and relays
Gmail dot and plus aliases are normalized, and privacy relay addresses are noted with a small weight, not blocked.
Questions
Is there a free checker?
Yes. The disposable e-mail checker on this site is free, and every domain has its own page with what we know about it.
Is the API only for e-mail?
No. The same call also scores network, device and linked accounts, so you get one decision per signup instead of an e-mail verdict alone.
How fresh is the list?
The disposable domain list refreshes daily and cloud IP ranges refresh every few hours.
What does it cost?
1,000 checks a month are free with no card. Paid plans start at $29 a month for 10,000 checks.
