What it does

Checks a list of email addresses and returns a clear status for each: syntax validity, domain existence, disposable-email detection, and a real SMTP-level mailbox check — without ever sending an actual email.

Why it's different

You only pay for determined results. Addresses we genuinely can't verify (timeouts, unreachable servers) are returned as unknown and are never charged — most verification tools charge for every row regardless of outcome.
Blanket-reject detection. Some mail providers reject every unverified address with an identical generic error specifically to defeat verification tools. We detect this pattern and report it honestly as unknown instead of falsely marking a real, working address as invalid.
Catch-all detection. If a domain accepts mail to any address, we flag it as risky rather than reporting false confidence that a specific address is deliverable.
Respectful of mail servers. Checks are throttled per mail domain, so we never hammer a single provider hard enough to get flagged or blocked.

Input

Field	Description	Default
`emails`	List of email addresses to verify (or a dataset/KV store reference)	—
`smtpTimeoutMs`	Timeout per SMTP connection attempt	10000
`maxConcurrentPerDomain`	Max simultaneous checks against one mail domain	2 (max 3)
`checkCatchAll`	Detect catch-all domains	true
`checkRoleAccounts`	Flag role-based addresses (info@, admin@, etc.)	true

Output

One record per address:

{
  "email": "name@example.com",
  "status": "valid",
  "reason": "Mailbox accepted",
  "isDisposable": false,
  "isRoleAccount": false,
  "isCatchAll": false,
  "possibleBlanketReject": false,
  "mxRecordFound": true,
  "checkedAt": "2026-10-03T12:00:00Z"
}

Possible status values: valid, invalid, disposable, risky, unknown.

Notes

unknown is a legitimate, honest outcome — not a failure. It means we could not conclusively determine deliverability (server timeout, or a provider that uniformly rejects all unverified probes).
This Actor never sends actual email — verification stops before the DATA command in every case.
Pricing applies only to valid, invalid, risky, and disposable results.
