Easy Email Verification checks whether email addresses exist and are safe to send to. Verify one address at a time, upload a CSV or TXT list for bulk processing, or call the REST API. Each check covers syntax, typo suggestions, domain and MX records, SMTP mailbox, catch-all, disposable, role-based and free-provider detection. Start free with 50 verifications per day, or pay as you go from US$ 4 per 500 credits that never expire.
