Email & Domain Validator (DNS-only, Privacy-first)

Keywords: email validator, MX record check, disposable email detection, role account filter, typo domain suggestion, bulk email cleaner, no SMTP verification.

Clean email lists without SMTP probing. For each address: syntax, DNS/MX, disposable domain, role account (info@…), and typo suggestions (gmial.com → gmail.com). Nothing stored beyond your run dataset.

Why this Actor

• No SMTP — never touches mail servers (safer for IP reputation)
• Fast DNS cache per domain; thousands of addresses in seconds
• Privacy-first: process in memory, write only to your Apify dataset
• Clear verdicts: valid · risky · disposable · undeliverable · invalid · unknown

Example input

{
  "emails": [
    "hello@gmail.com",
    "info@example.com",
    "test@gmial.com",
    "user@mailinator.com"
  ],
  "resolver": "system",
  "concurrency": 20
}

You can also paste a list into emailsText (newline or comma separated). Use resolver: "doh" (Cloudflare DoH) if system DNS is unreliable.

Output fields

Field	Meaning
syntaxValid / syntaxError	RFC-style syntax
domainExists, hasMx, nullMx, mxHosts, hasA	Live DNS
acceptsMailLikely	MX or A-record fallback
isDisposable / isRoleAccount	disposable list / role local-parts
suggestedDomain	common-provider typo fix
verdict	overall label

Pricing (pay per event)

• Validated email — $0.0002 per result (~$0.20 / 1,000)
• Actor start ~$0.00005

Limitations

Cannot prove an individual mailbox exists (no SMTP). Disposable lists are never complete. Only process lists you are allowed to handle.

Use cases & scheduling

• Clean a list before a campaign — paste emails into emailsText, export rows where verdict is valid.
• Sign-up form hygiene — detect disposable/temporary email domains and typos (gmial.com → gmail.com).
• Filter role accounts — drop info@, sales@, support@ from outreach lists.
• Recurring CRM hygiene — schedule weekly against a fresh export so new bad domains are flagged early.
• Bulk MX record check — see which domains have MX, null MX, or only an A record.

Tip: create an Apify Schedule for the Actor or one of the tasks below to turn it into a recurring monitor, and add a webhook/integration to get results in Slack, email or Google Sheets.

FAQ

Does it check if the mailbox really exists?
No. There is no SMTP probing, so it cannot confirm an individual inbox — it checks syntax, DNS/MX, disposable and role patterns.

Why no SMTP?
SMTP probing hurts IP reputation and is often blocked or inaccurate on catch-all servers. DNS-only is fast and safe.

system vs doh resolver?
system uses the platform DNS; doh uses Cloudflare DNS-over-HTTPS when system DNS is unreliable.

Is my list stored?
Only in your own run dataset. Process only lists you are allowed to handle.
