KenyaThe Disposable Email Checker API by API Ninjas analyzes email addresses in real time to determine if the domain belongs to a temporary, throwaway, or burner email service (such as Mailinator, 10MinuteMail, GuerrillaMail, or TempMail). In online applications, disposable email addresses are heavily abused by botnets and fraudsters to claim sign-up referral bonuses, spam forums, create burner accounts, and bypass trial limits.
Integrating this API during user registration blocks burner accounts instantly, saving Nigerian SaaS and marketplace founders server resources and email deliverability reputation.
