Email Validator Bulk: MX, Disposable, Typo, No SMTP

Validate thousands of e-mail addresses in one run and get a clear verdict for each one: valid, risky or invalid, with a 0-100 score and the reasons. Built for cold email, list cleaning before an import, sign-up forms and CRM hygiene.

It never contacts a mail server. No SMTP RCPT TO, no "ping", no test message. Every check uses public DNS and a bundled list, so your IP is never burned, you never break a mail provider's terms, and results come back in seconds, not minutes. The trade-off is explained in Data source and limits.

At US$ 1.50 per 1,000 addresses it costs a fraction of the leading validators in the Store (US$ 0.10 per address, i.e. US$ 100 per 1,000).

What it checks

Check	What you get
Syntax (RFC 5321/5322)	One @, local part up to 64 characters, no leading/trailing/double dots, allowed characters only, valid domain labels and TLD, total length up to 254. Accented domains (bücher.de) are converted to punycode.
Domain exists	A DNS lookup tells whether the domain is registered (domainExists).
MX records	Mail servers by priority (mxHosts). Falls back to the A/AAAA record when there is no MX, as RFC 5321 says (acceptsMailViaARecord). A null MX (RFC 7505) means the domain declares it receives no mail.
Disposable domain	Matched against a list of about 10,000 known throwaway domains (Mailinator-style), including subdomains.
Role account	admin@, info@, support@, sales@, contato@, noreply@ and about 70 more, in English and Portuguese.
Typo in the domain	gmial.com, gmai.com, gmail.con, hotmial.com, outlok.com... with the corrected address in suggestedEmail.
Free mailbox provider	freeProvider is true for Gmail, Outlook, Yahoo, iCloud, UOL and other large public providers.

Input

Field	Description
emails	Addresses to validate, up to 5,000 per run. Jane <jane@acme.com> and mailto:jane@acme.com work too. Duplicates (case-insensitive) are dropped.
dnsMode	auto (default): normal DNS, switching to DNS over HTTPS if port 53 is blocked. udp or doh to force one.
dohProvider	Cloudflare (default) or Google Public DNS, used for DNS over HTTPS.

The default input has 6 addresses and finishes in a few seconds.

Output

One dataset item per address (abridged):

{
  "input": "Maria Souza <maria@gmail.con>",
  "email": "maria@gmail.con",
  "localPart": "maria",
  "domain": "gmail.con",
  "status": "ok",
  "verdict": "invalid",
  "score": 5,
  "syntaxValid": true,
  "domainExists": false,
  "hasMx": false,
  "mxHosts": [],
  "acceptsMailViaARecord": false,
  "disposable": false,
  "roleAccount": false,
  "freeProvider": false,
  "typoSuggestion": "gmail.com",
  "suggestedEmail": "maria@gmail.com",
  "reasons": ["domain_does_not_exist", "possible_typo"],
  "checkedAt": "2026-11-05T12:00:00+00:00"
}

Verdict and score. The score starts at 100. Subtract: no MX but an A record 30, disposable domain 70, possible typo 45, role account 25. valid is 80 or more, risky is below 80. These are always invalid (score at most 5): bad syntax (score 0), domain does not exist, null MX, or no mail server at all.

Reasons (list in reasons): invalid_syntax, domain_does_not_exist, null_mx, no_mail_server, no_mx_records_a_record_only, disposable_domain, possible_typo, role_account.

status: ok (checked, charged), syntax_error (malformed address, syntaxProblem says why, free), error (not an address, or DNS failed, free) and duplicate (free).

How much does it cost?

Pay per event, with no platform usage added to your bill:

Event	When	Price
apify-actor-start	Once per run, charged by Apify	US$ 0.00005 (Apify default)
email	Once per address checked against DNS (any verdict)	US$ 0.0015

Malformed addresses, inputs that are not addresses, duplicates and DNS failures are free.

How the email price (US$ 1.50 per 1,000 addresses) was set:

• Apify compute costs US$ 0.20 per compute unit (1 CU = 1 GB for 1 hour). The Actor runs with 256 MB. An address needs one to three DNS queries and a few milliseconds of CPU, and addresses on the same domain share one lookup, so compute is a small fraction of a cent per 1,000 addresses.
• After Apify's 20% commission, US$ 0.0015 leaves US$ 0.0012 per address, far above the compute cost, so even a one-address run is profitable.
• Store comparison (November 2026): the leading validator charges US$ 0.10 per address and the median of the niche is about US$ 0.001. We sit at the cheap end on purpose: the product is DNS-only, so it does not need a premium, and a low price makes it the default choice for cleaning large lists.

$0.0015 per e-mail checked (email event, pay per event). Charged once per e-mail address checked against DNS (verdict, score, MX, disposable, role and typo checks). Malformed input, duplicates and DNS errors are free.

You get	Free tier	Bronze tier (10% off)	Gold tier (30% off)
100 e-mail checkeds	$0.15	$0.14	$0.10
1,000 e-mail checkeds	$1.50	$1.35	$1.05
10,000 e-mail checkeds	$15.00	$13.50	$10.50

Discounts follow your Apify subscription tier: Bronze 10%, Silver 20%, Gold and above 30%. No subscription to this Actor and no charge for platform usage: you pay only for results. The Apify Free plan includes $5 of monthly credit, enough for about 3,333 e-mail checkeds at the list price. You can cap the cost of any run with Maximum cost per run; the Actor stops when it is reached.

Data source and limits

Source. Public DNS (MX, A and AAAA records) read from Cloudflare 1.1.1.1 and Google Public DNS, over UDP/TCP 53 or DNS over HTTPS, plus a bundled list of disposable domains. Nothing is scraped and no login is needed.

No SMTP verification. This Actor does not connect to the recipient's mail server, does not run RCPT TO or VRFY, and does not send any message. That means it cannot tell whether a specific mailbox exists: jane@acme.com gets valid when the syntax is right and acme.com has a mail server, even if there is no user "jane". Catch-all domains and full or disabled mailboxes are invisible to it. Think of valid as "deliverable in principle, no red flags", not "confirmed mailbox". It is the safe first filter: it removes malformed, dead-domain, disposable and mistyped addresses, which are most of the bounces in a typical list. Pair it with a sending tool that handles bounces for the rest.

Disposable list. disposable-email-domains by the disposable-email-domains contributors, disposable_email_blocklist.conf (commit a72c0ce, 4 November 2026), released under CC0 1.0 Universal (public domain dedication, no attribution required; credited here anyway). The copy in this Actor lives in src/data/disposable_domains.txt, with its source in src/data/SOURCE.txt. New throwaway services appear daily, so the list is a snapshot.

Other limits. Up to 5,000 addresses per run. Quoted local parts ("john doe"@acme.com), comments, IP-literal domains and non-ASCII local parts are reported as invalid syntax, because most mail servers refuse them. Role-account and typo lists are built in and cover common cases, not every language. Results are a snapshot at checkedAt; DNS caching can delay changes by minutes to hours. A DNS timeout or SERVFAIL returns status: "error" and is not charged, so you can re-run those addresses.

Privacy: addresses are processed in memory and written only to your own run dataset. Only the domain part is sent to DNS resolvers; the part before the @ never leaves the Actor.

Not affiliated: this Actor is an independent tool, not affiliated with, endorsed by or sponsored by Google, Microsoft, Cloudflare, Yahoo or any mailbox or DNS provider named on this page; names are used only to describe what is checked.

Usar em português

Valida listas de e-mails em lote, só com DNS: sintaxe RFC, domínio existente, registros MX, domínio descartável (mailinator e similares), endereço de função (admin@, contato@, noreply@), erro de digitação no domínio (gmial.com vira gmail.com, com o endereço corrigido em suggestedEmail) e uma pontuação de 0 a 100 com veredito valid, risky ou invalid.

Não há verificação SMTP: o Actor nunca conecta ao servidor de e-mail do destinatário, então não sabe se a caixa maria@empresa.com.br existe, só se o domínio recebe e-mail e se o endereço tem sinais de problema. Por isso é seguro para o seu IP e para os termos dos provedores, e roda em segundos.

Preço: US$ 0,0015 por e-mail validado (US$ 1,50 por mil). Endereços malformados, duplicados e falhas de DNS não são cobrados. Você pode limitar o gasto com "Maximum cost per run": o Actor para quando o teto é atingido. A lista de domínios descartáveis é de domínio público (CC0).

Quanto custa: $0.0015 por resultado (email); 1.000 resultados saem por $1.50. Desconto pelo nível da assinatura Apify: Bronze 10%, Silver 20%, Gold ou acima 30%. Erros e consultas sem resultado não são cobrados. Use também pela API ou por agentes de IA no servidor MCP da Apify (https://mcp.apify.com/?tools=br_data_hub/email-validator-bulk).
