Email List Checker: Syntax, MX & Disposable Domains

The NanoScrape Email Verifier Scraper is an Apify actor that extracts structured web data from Email Verifier. It returns 12 fields per result including email, status, syntax_ok, mx_ok, mx_provider, priced at $2/1k email, with no API key or monthly subscription required.

Check email lists in bulk for bad syntax, missing MX records, disposable domains and role addresses (info@, sales@). Adds a catch-all heuristic and a 0-100 score per address. No mailbox-level check: it does not confirm an address exists. Pay per email.

Input example — showcase (full detail)

{
  "emails": [
    "[email protected]",
    "[email protected]",
    "[email protected]",
    "not-a-real-email",
    "[email protected]"
  ]
}

Output example — real dataset item (PII scrubbed)

{
  "email": null,
  "status": "ok",
  "syntax_ok": true,
  "mx_ok": true,
  "mx_provider": "google_workspace",
  "disposable": false,
  "role_account": false,
  "catch_all": "unknown",
  "catch_all_method": "heuristic",
  "score": 95,
  "checked_at": "2026-10-26T08:24:12Z"
}

Cost math

Priced at $0.002 per email verified ($2.00 per 1,000). 10,000 emails ≈ $20.00. The first runs land inside Apify's $5/mo free-tier credit — pay only for what you extract, no monthly subscription.

What this checker does and does not do

Each address is checked for syntax, the domain's MX records, a disposable-mail domain and a role local part (info@, support@ and similar). A catch-all guess is derived from the MX host name. There is no mailbox-level SMTP check: the actor never contacts the recipient's mail server, so it cannot tell you whether a mailbox exists or whether a message will be delivered.

How the status is set

invalid: bad syntax, no MX records, or a disposable domain
risky: a role address, or a likely catch-all
ok: none of the checks flagged the address. This does not mean the mailbox exists.

Output: 12 fields per address

Field	Type	Example	Meaning
`company_id`	string	`acme-42`	Echoed from `companies`; left out for addresses from `emails`
`email`	string	`[email protected]`	The address as checked (trimmed)
`status`	string	`risky`	`ok`, `risky` or `invalid`
`syntax_ok`	boolean	`true`	Passes the syntax check
`mx_ok`	boolean	`true`	Domain has at least one MX record
`mx_provider`	string	`google_workspace`	Provider derived from the MX host; left out when `mx_ok` is false
`disposable`	boolean	`false`	Domain is on the disposable-mail list
`role_account`	boolean	`true`	Local part is a role name such as info or sales
`catch_all`	string	`unknown`	`likely` or `unknown`, a heuristic from the MX host name
`catch_all_method`	string	`heuristic`	Always `heuristic`: the mail server is not contacted
`score`	integer	`55`	0-100 for sorting a list, not a probability of delivery
`checked_at`	string	`2026-10-26T10:30:00Z`	ISO 8601 timestamp of the check

Sample output row

{
  "company_id": "acme-42",
  "email": "[email protected]",
  "status": "risky",
  "syntax_ok": true,
  "mx_ok": true,
  "mx_provider": "google_workspace",
  "disposable": false,
  "role_account": true,
  "catch_all": "unknown",
  "catch_all_method": "heuristic",
  "score": 55,
  "checked_at": "2026-10-26T10:30:00Z"
}

Use cases

Pre-send list cleanup: drop addresses with broken syntax or domains without MX records before outreach
Sign-up and lead lists: flag disposable-mail domains
Role vs personal: separate info@ and support@ from personal addresses
Catch-all hints: spot domains whose mail host looks like shared web hosting
CRM join-back: pass a company_id and match every row to your own records
