Recently added disposable domains
A live sample of the newest root domains added to our blocklist. Disposable providers rotate domains constantly — this is why static lists fall behind.
Why don't we publish the full list? Two reasons: it changes daily (any snapshot you download is stale within a week), and full public dumps help disposable providers check which of their domains are burned. The API always queries the live database — including wildcard subdomain matching that a raw list can't give you.
Well-known disposable email providers
The most common services our API blocks include Mailinator, 10MinuteMail, Guerrilla Mail, Temp-Mail.org, YOPmail, ThrowAwayMail, GetNada, Moakt, Dropmail, and hundreds of smaller providers — each of which operates dozens to thousands of rotating domains. For a deeper explanation of how these services work and a categorized sample list of 250+ domains, read our guide: What Are Disposable Emails?
How the database is maintained
Domains enter the blocklist through automated scrapers that monitor temp-mail services 24/7, MX-record fingerprinting that catches catch-all temp servers early, community reports to report@tempmailchecker.com, and manual review before inclusion. Details on our about page.
Integrating the list into your signup flow takes one GET request — see code examples for cURL, JavaScript, Python, PHP, Go, and Ruby.
