How this service works
Instant disposable email detection — checks against 5,000+ known temporary email domains (Guerrilla Mail, Mailinator, Temp Mail, 10MinuteMail, and more). Returns boolean result. Maintaining this blocklist yourself requires weekly updates from multiple sources. Accepts USDC payments on Base and Solana
Output
A boolean indicating whether the submitted email address belongs to one of 5,000+ known disposable/temporary email domains such as Guerrilla Mail, Mailinator, Temp Mail, or 10MinuteMail.
Example use cases
Filter fake signups during registration
“We're getting a lot of suspicious account creations with temporary email addresses. Can you check each signup email to see if it's from a disposable service like Mailinator or 10MinuteMail before we create their account?”
Prevent fraud in loyalty programs
“I need to validate that customer email addresses aren't using throwaway services before I enroll them in our rewards program. Can you quickly check if an email belongs to one of those guerrilla mail domains?”
Improve marketplace seller verification
“Our marketplace has a problem with sellers using fake emails to create multiple accounts. Can you screen their signup email to detect if it's from a temporary email service so we can flag suspicious vendors?”
