Email Verify Bulk

by APEX Bulk email verification in Email & messaging

x402 APIPassing, checked 3 h ago

Bulk email verification: up to 100 addresses in one call. Clean an email list: pass [email protected],[email protected] (up to 100 in one call) and get a verdict per address plus totals. Each address is checked for usable shape, for MX records read live over DNS, against 25 known disposable-mail domains and against 27 role-account names like info, support and admin. Verdicts are deliverable-domain, role-account, disposable, undeliverable, unknown or invalid, and each one says in words what it means.
