How this service works
Disposable / temporary email detection: is this address or domain a throwaway (Mailinator, Guerrilla Mail, 10minutemail, YOPmail...), a free webmail provider (Gmail, Outlook...), or a role address (info@, admin@)? Includes MX presence and a deliverability verdict. Signup fraud prevention and list hygiene. $0.01 per address.
Output
Returns a JSON object indicating whether the email is from a known disposable/temporary provider (e.g. Mailinator, Guerrilla Mail, 10minutemail, YOPmail), whether it is a free webmail provider (e.g. Gmail, Outlook), whether it is a role address (e.g. info@, admin@), whether valid MX records exist for the domain, and an overall deliverability verdict.
Example use cases
Signup fraud prevention at registration
“A new user just tried to sign up with 'temp_9182@guerrillamail.com' — can you check if that's a disposable or temporary email address so I can decide whether to block the registration?”
Email list hygiene before campaign
“I'm about to send a marketing campaign to my list — can you check if 'info@example.com' is a role address or a throwaway domain that I should remove to protect my sender reputation?”
B2B lead qualification check
“We got a new lead who gave the email 'contact@yopmail.com' — is that a real business address or a disposable webmail domain, and does it have valid MX records?”

Side effects
- Missing or malformed email address parameter returns an error
- Unknown or newly created disposable domains may not be flagged if not in the database
- MX lookup failures due to DNS timeouts may affect the deliverability verdict
- Legitimate custom domains that happen to share patterns with disposable providers may be incorrectly flagged
