Email Validator – MX & Disposable Check

What it does

Validate email addresses in bulk without sending any mail: each address gets a verdict (ok, role, disposable, no_mail_server, domain_not_found or invalid_syntax) from a strict syntax check, the domain's MX records (including RFC 7505 null MX), a list of about 9,900 disposable domains, free-mail and role-account lists, a typo suggestion (gmial.com → gmail.com) and, optionally, the domain's SPF and DMARC policy. Built for cleaning sign-up and lead lists, blocking throw-away addresses in forms, and AI agents that need a quick yes/no before they email someone. $0.40 per 1,000 emails.

Price per delivered record

Apify free plan: up to 10 items per run. Paid plans have no per-run cap; set maxTotalChargeUsd to cap spend.

Call it from code, an agent or the Console

curl -X POST "https://api.apify.com/v2/actors/sfoln~email-validator/run-sync-get-dataset-items" \
  -H "Authorization: Bearer $APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"emails":["support@apify.com","jane.doe@gmial.com","info@example.com"]}'

}

POST https://api.apify.com/v2/actors/sfoln~email-validator/runs?maxTotalChargeUsd=1
GET  https://api.apify.com/v2/actor-runs/{runId}            # until status is SUCCEEDED

Authenticate with an Apify API token. MCP clients can instead sign in with OAuth when prompted. Example prompt for an agent: Validate these email addresses and tell me which ones to drop from my list and why: support@apify.com, jane.doe@gmial.com, info@example.com.

Input fields

Paste email addresses (one per line) or pass an array. Each address produces one dataset record with a verdict, flags and a typo suggestion. Nothing is sent to the mailboxes.

{
  "emails": [
    "support@apify.com",
    "jane.doe@gmial.com",
    "info@example.com"
  ]
}

One record per input item

Records land in the run's dataset; a synchronous call returns them directly. Each has a status (ok is charged; everything else is free) and a charged flag. The run's OUTPUT record totals items and charges.

Questions

Does it check whether the mailbox exists?

No. It never connects to the mail server (SMTP probing from cloud IPs is unreliable and gets blocked). It settles what DNS and the bundled lists can settle: invalid syntax, domains that do not exist or accept no mail, and disposable domains. For a mailbox-level verdict (valid, invalid, catch-all) run the addresses that pass through Email Verifier.

Which addresses are charged?

Every address that gets a verdict, including invalid syntax, is charged one email event ($0.0004). An address whose domain could not be looked up because DNS failed comes back with status error and verdict unknown and is not charged; run it again later.
