Bulk Email Verifier Pro

Bulk-verify email deliverability with DNS MX/A checks, disposable / role / free-provider flags, and typo suggestions — a clear per-email verdict at $0.005 per verified email (20× below the $0.10-per-result incumbent). No SMTP probing, no proxy, no residential IPs. You pay only for emails we actually verify — malformed input and DNS failures are free.

Pricing promise: apify-actor-start $0.0001 (one-time) + email_verified $0.005 charged once per email we actually verify against DNS (deliverable, undeliverable-no-mail-server, or risky-disposable). Malformed input, placeholder/example domains, and DNS failures are never charged — no-result = no charge. Each result row carries a dnsChecked flag so you can see exactly what was billed.

What it checks (in order, cheapest first)

1. Syntax — RFC-pragmatic validation (local part bounded, ≥2-char alpha TLD). Rules ported from our published Website Contact Extractor, so the verifier is never fooled by demo/placeholder emails (you@company.com, info@example.com) or scraped junk.
2. Domain MX/A via DNS — the domain must be configured to receive mail. MX is preferred, with an A-record fallback (per RFC). Lookups are cached per domain, so a list of 5,000 addresses at one company costs one DNS query, not 5,000.
3. Disposable / throwaway detection — a curated static list of common disposable domains (mailinator, guerrillamail, 10minutemail, yopmail, …). No external API call.
4. Role-account detection — flags shared/role mailboxes (info@, sales@, support@, admin@, noreply@, …). B2B buyers usually filter these; most incumbents don't flag them.
5. Free-provider detection — gmail.com, yahoo.com, outlook.com, … → freeProvider: true (a B2B list usually wants company domains).
6. Typo suggestion — obvious typos against well-known domains, e.g. gmial.com → gmail.com, returned as didYouMean.

What we deliberately DON'T check (and why)

• No SMTP mailbox probing. Connecting to mail servers to confirm a specific mailbox exists gets your IPs blocklisted, is slow at scale, and is unreliable under greylisting and catch-all servers. We'd rather be honest than overclaim.
• Therefore deliverable means the domain is configured to receive mail (MX or A record) — it does NOT guarantee the specific mailbox exists. risky flags disposable domains (they accept mail but are low-value/junk). unknown means the DNS check couldn't complete (transient error) and you are not charged.

If you need per-mailbox SMTP confirmation, pair this actor with an SMTP-probing service downstream — but most deliverability screening and list-hygiene jobs only need what we provide, at 20× the value.

Input

Field	Type	Required	Default	Description
emails	array	yes	—	Emails to verify. Bare addresses or Display Name <a@b.com> envelopes. Messy input (whitespace, mixed case, blanks, duplicates) is handled.
skipDisposable	boolean	no	false	If true, disposable addresses are dropped from the output. Default false keeps them with a risky verdict + disposable: true so you can see what was filtered.
concurrency	integer	no	10	Parallel emails (1–25). DNS is cached per domain.

{
  "emails": [
    "team@stripe.com",
    "notrealperson@thisdomaindoesnotexistxyz.com",

    "Jane <jane.doe@gmail.com>"
  ],

}

Output

One row per input email (or per malformed entry). Duplicates are deduped case-insensitively.

Field	Type	Description
email	string	The normalized address (lowercased). For malformed input, the original raw string.
valid	bool|null	true = domain accepts mail; false = undeliverable (bad syntax or no mail server); null = unknown (DNS check failed).
status	string	deliverable | undeliverable | risky | unknown.
reason	string	Human-readable, always populated.
domain	string|null	The email domain.
hasMx	bool|null	true if an MX record exists. null if the DNS check failed.
mxHost	string|null	Highest-priority MX exchange host, or null if no MX record (even when an A-record fallback makes the domain deliverable).
disposable	bool	true if the domain is a known throwaway provider.
role	bool	true if the local part is a shared/role mailbox.
freeProvider	bool	true if the domain is a free consumer provider (gmail/yahoo/outlook/…).
didYouMean	string|null	Suggested domain for an obvious typo (e.g. gmail.com), or null.
dnsChecked	bool	true if the verdict came from a live DNS check (this is what you're billed for). false for malformed/placeholder rows that were rejected before DNS — never charged.
checkedAt	string (ISO)	UTC timestamp of the check.

Charge audit for this run: 6 email_verified charges (the six dnsChecked: true rows) + 1 apify-actor-start. The two dnsChecked: false rows (malformed plainjunk, placeholder info@example.com) are not charged — exactly as promised. (mxHost values reflect Google's rotating MX hosts at run time; gmial.com is a real registered domain that accepts mail, so it's correctly deliverable and flagged didYouMean: gmail.com.)

Pricing vs. the market

	Per-result price	Charges on errors?	Role flag	Disposable flag	Typo suggestion
Bulk Email Verifier Pro	$0.005	No (malformed/DNS-fail free)	✅	✅	✅
michael.g/email-verifier-validator (incumbent, 1,250+ users)	$0.10	varies	—	—	—

We charge ~20× less per verified email, and we don't charge you for input we couldn't verify. That price transparency is the differentiator — the same deliverability screening for list-hygiene and B2B lead cleanup, at a fraction of the cost.

Troubleshooting

• A real company address shows unknown — a transient DNS failure (resolver timeout). Re-run; DNS is generally stable and the cached-per-domain design keeps retries cheap.
• deliverable but the address still bounces — we verify the domain accepts mail, not the specific mailbox (we don't SMTP-probe by design). Use role / freeProvider / disposable to triage quality before sending.
• An address you expected is missing from the output — you set skipDisposable: true and it was a throwaway domain, or it was an exact duplicate of an earlier address (deduped). Set skipDisposable: false to see everything.
• didYouMean is null for an obvious typo — we only suggest against well-known domains to avoid proposing junk. For niche domain typos, no suggestion is returned.
• Large lists at one company are slow / fast? — DNS is cached per domain, so 5,000 addresses at one company is one lookup; raise concurrency toward 25 for big, diverse lists.

Notes

• No API keys, no proxy, no residential IPs. The only network hop is standard DNS (UDP). Margin-positive from the first email.
• Disposable-domain list is a curated static set (not exhaustive) — we update it periodically; it intentionally errs toward the common throwaway providers.
