Know what kind of email address you're dealing with, before you act on it. EmailKind identifies the provider behind any address — Google Workspace, Microsoft 365, Zoho and => 150+ others — and classifies it as business, personal, disposable, education or role-based. One GET request, under 50ms.
Signup forms can't tell a company address from a throwaway one, and email verification tools answer the wrong question: check if a mailbox exists. EmailKind reads MX and SPF records to classify the domain and also sees through the security gateways that hide the real mailbox
