Email Verifier Lite: bulk syntax, MX and disposable email check

Clean an email list fast and cheaply before you pay for full verification or hit send. For every address you get a status, a 0-100 quality score and the reasons: whether the syntax is valid, whether the domain exists and has mail (MX) servers, whether it's a disposable / temporary address, a role account (info@, sales@...), a free provider (Gmail, Yahoo, Outlook...), and a typo suggestion (gmial.com → gmail.com, hotmail.con → hotmail.com).

Important: this actor does not connect to mail servers (no SMTP). It can't confirm that a specific mailbox exists, only that the address is well-formed and its domain can receive email. Use it as a cheap pre-filter. It removes the obvious junk so you only send good-looking addresses to a full SMTP verifier, or straight to your campaign if a lighter check is enough.

What it checks

Check	How
Syntax	RFC 5321/5322-style rules: one @, allowed characters, length limits, no double or edge dots, valid domain labels and TLD. International domains (münchen.de) are converted to punycode.
Cleanup	Trims spaces, takes the address out of "Name" <email> and mailto: links, lower-cases it into normalized. Duplicates are removed.
Domain and MX	Live DNS lookup of MX records, plus A/AAAA records when there's no MX. Detects non-existent domains and "null MX" domains that say they accept no mail. Uses the system resolver, with Cloudflare DNS-over-HTTPS as a fallback. Each domain is looked up once per run.
Disposable	Bundled list of 121,000+ throwaway domains (Mailinator, 10minutemail, Guerrilla Mail...), including their subdomains.
Role account	100+ shared-inbox names like info, sales, support, admin, billing, hr, noreply, postmaster.
Free provider	150+ consumer mailbox providers: Gmail, Yahoo, Outlook/Hotmail, iCloud, AOL, Proton, GMX, Yandex, ISP mail... Useful to separate B2B from B2C leads.
Typo	Suggests the intended address when the domain is one or two keystrokes away from a popular provider, or has a mistyped TLD (.con, .cmo).

Statuses and score

status	meaning	typical score
valid_format_has_mx	Well-formed and the domain has mail servers	65-95 (lower for role accounts and likely typos)
no_mx	Domain doesn't exist, has no MX, or declares a null MX	0-25
disposable	Temporary / throwaway email domain	10
invalid_syntax	Not a valid email address	0
unknown	DNS didn't answer (rare). Retry later.	40

Rule of thumb: keep score ≥ 80, review 50-79 (role accounts, typos), drop < 50.

Input example

{
  "emails": [
    "john.doe@gmail.com",
    "Info@Apify.com",
    "someone@gmial.com",
    "test@mailinator.com",
    "\"Jane Roe\" <jane.roe+news@outlook.com>",
    "not-an-email@"
  ]
}

You can paste one address per line, or comma/semicolon-separated lists.

Output example

{
  "email": "someone@gmial.com",
  "normalized": "someone@gmial.com",
  "status": "no_mx",
  "score": 25,
  "reason": "no MX record; domain has only an A/AAAA record (mail delivery unlikely)",
  "isValidSyntax": true,
  "syntaxError": null,
  "localPart": "someone",
  "domain": "gmial.com",
  "hasMx": false,
  "mxRecords": [],
  "hasARecord": true,
  "domainExists": true,
  "nullMx": false,
  "isDisposable": false,
  "isRoleAccount": false,
  "isFreeProvider": false,
  "hasPlusTag": false,
  "didYouMean": "someone@gmail.com",
  "dnsError": null,
  "checkedAt": "2026-10-05T23:40:12Z"
}

A SUMMARY record in the run's key-value store has counts by status.

Pricing

Pay per result: $0.75 per 1,000 emails checked (plus a tiny per-run start fee). Duplicates are removed before checking, so you don't pay for them twice. Runs are fast: thousands of addresses per minute, because each domain is looked up only once.

FAQ

Does it tell me if the mailbox really exists? No. Only an SMTP check, which talks to the recipient's mail server, can get close to that, and even it's unreliable on catch-all domains and big providers like Gmail and Outlook. This actor never contacts mail servers. That's why it's fast, cheap and won't get your IP blocklisted. Run it first, then send only the valid_format_has_mx addresses to a full verifier if you need mailbox-level certainty.

Why is a real company address marked role account? Addresses like info@ or sales@ usually reach shared inboxes. They're valid, but they reply less and complain more in cold outreach, so the score is lower. Filter on isRoleAccount however you like.

Is my list stored anywhere? Only in your own Apify run storage. Domains are looked up through DNS; full addresses are never sent to any third party.

Where does the disposable list come from? It's bundled from the open-source disposable-email-domains list (npm package version 1.0.62, MIT license): 121,570 domains plus 399 wildcard domains that also cover all their subdomains.

Use it with n8n, Make or Zapier

Call the actor from n8n, Make or Zapier whenever a form submission, CRM contact or Google Sheets row arrives. Then route the row by status or score: add it to your list, flag it for review or reject it. For big lists, upload a CSV column into the emails field and export the results as CSV or Excel.
