What you get

Syntax check — catches malformed addresses instantly
MX record check — confirms the domain actually accepts mail (including RFC 7505 "null MX" domains that explicitly reject all mail)
Live SMTP deliverability check — connects to the real mail server and asks whether the specific mailbox exists, catching typos and dead addresses that pass a syntax/MX-only check
Disposable domain detection — flags mailinator.com, guerrillamail.com, and 50,000+ other throwaway domains
Role account detection — flags info@, admin@, support@, sales@ and similar shared inboxes
Catch-all domain detection (optional) — flags domains that accept mail for any address, which makes deliverability unverifiable for a single mailbox
Final status per email: valid, invalid, risky, or unknown

Use cases

Scrub a purchased or scraped lead list before an email campaign
Reduce bounce rate and protect sender reputation before a cold-outbound send
Validate signup-form emails in a batch backfill
Deduplicate and grade an email list by deliverability confidence

How to use

Paste your list into Emails (one per line)
Leave Check SMTP deliverability on for the most accurate results (some networks block outbound SMTP — those checks report unknown rather than failing)
Optionally enable Check for catch-all domains to catch domains where SMTP can't tell you a specific mailbox is real
Run the actor — results appear in the Dataset tab

Output format

Each dataset record:

{
  "email": "someone@example.com",
  "isValidSyntax": true,
  "domain": "example.com",
  "hasMxRecord": true,
  "mxHost": "mail.example.com",
  "isDisposable": false,
  "isRoleAccount": false,
  "smtpCheck": "deliverable",
  "isCatchAll": false,
  "status": "valid",
  "reason": "verified_deliverable"
}

status is the field to filter/sort on: valid (safe to send), risky (disposable, role-based, or catch-all — send with caution), invalid (bad syntax, no mail server, or the mailbox doesn't exist), unknown (deliverability couldn't be confirmed, usually because the target mail server didn't respond to the SMTP check).
