Disposable e-mails poison your data
Services like Mailinator, Guerrilla Mail, 10 Minute Mail and hundreds of similar providers hand out throw-away inboxes that work just long enough to confirm a signup — then disappear.
The result: free-trial farming, fraud, abuse signups, broken transactional flows and a slow accumulation of unreachable contacts in your CRM. Generic syntax validation does not catch any of this.
What it does
Real-time check
Single REST call returns a verdict in milliseconds — fast enough to gate signup forms inline.
Broad coverage
Detection database covers thousands of disposable, anonymous and burner-mail providers across regions and languages.
Continuous updates
New disposable services pop up constantly. Our list is curated and refreshed continuously — you don't have to maintain one.
Functional inbox detection
Flags info@, sales@, noreply@ patterns alongside disposable verdicts — both signals matter for lead quality.
Provider classification
Distinguishes disposable from regular freemail (gmail.com) and from business domains — you decide what's acceptable.
Simple verdict
A single disposable field — YES, NO or UNKNOWN — trivial to wire into existing form-validation flows.
Where the detector fits
Free-trial protection
Block users from creating dozens of trial accounts with rotating throw-away addresses.
Fraud prevention
Disposable e-mail is a strong signal in fraud-scoring pipelines — combine it with other risk indicators for a richer verdict.
Lead quality
Stop paying acquisition cost on contacts that vanish a day later — route disposable signups out of marketing automation.
Transactional reliability
Avoid sending invoices, contracts and password resets into burner inboxes that no one will ever check.
