What do the verification statuses mean? (valid, invalid, catch-all, unknown, disposable, role)
Understand valid, invalid, catch-all, unknown, disposable, and role results, including which outcomes use credits.
プロバイダーの制限Why are iCloud (icloud.com / me.com / mac.com) addresses not marked "valid"?
Learn why iCloud, me.com, mac.com, and Hide My Email addresses return unknown instead of valid.
プロバイダーの制限Why are Outlook / Hotmail / Live addresses not marked "valid"?
Learn why personal Microsoft addresses return unknown and how Microsoft 365 business domains differ.
検証結果What does an "unknown" result mean, and what should I do with it?
Unknown means the receiving mail system did not provide a reliable answer; it does not mean the address is bad.
検証結果Why is an address marked catch-all instead of valid?
Catch-all means the domain accepts every recipient without confirming whether the specific mailbox exists.
検証結果Why was an address I believe is active marked "invalid"?
Invalid is based on a concrete rejection from the receiving server, not a guess about the mailbox.
検証結果What does the "score" in the result mean?
The 0.0–1.0 score reflects deliverability confidence and should always be read together with the status.
検証結果Why did my result change when I re-verified the same address?
Cached results and temporary mail-server conditions can explain why a later verification returns a different status.
請求とクレジットWhich results consume credits?
See which verification outcomes cost one credit and which results are always returned free of charge.
請求とクレジットDo you charge for disposable / temporary email addresses?
Disposable-domain detection is free unless you explicitly request and complete a full live SMTP verification.
請求とクレジットAm I charged again if I verify the same address twice?
Repeat checks for the same account and address are free within 24 hours unless you request a force refresh.
請求とクレジットDo my credits expire?
Purchased and bonus credits stay in your account until you use them, with no monthly reset or expiration date.
信頼性とプライバシーDoes verification send a real email to the address?
Verification checks the receiving mail server but stops before transmitting any message body to the recipient.
