MillionVerifier
Verify one email per call. Use Play rows for multiple emails; bulk operations are disabled pending file, tenant ownership, and billing contracts. Keepok, invalid, disposable, catch_all, and unknown distinct. catch_all and unknown do not prove deliverability. A provider error or inconsistent verdict is a failed verification. Repeat verification can consume provider credits again.
The free BYOK connection probe validates the connected customer’s key internally and returns status only. Account balances do not establish per-call usage and are not included in the public response.
