B2B Email Deliverability Risk Gate

Run a read-only pre-send hygiene check on a B2B email list. The Actor returns one structured Dataset row per unique input address with a score, reason codes, and an operational decision:

• allow: syntax and MX passed, with no local high-risk flag.
• review: a human should review a role account, free provider, or unresolved MX lookup.
• suppress: malformed address, disposable domain, or no MX record.

This is a risk gate, not a mailbox-existence or delivery guarantee. It uses syntax checks, a small explicit disposable-domain list, a small role-prefix list, a small free-provider list, and DNS MX lookup (cached per domain). It does not send email, use SMTP RCPT TO, scrape websites, use proxies, access private data, or require an API key.

Companion B2B Email & Domain Tools:

• Need to discover corporate emails from a person's name + company domain? Use Corporate Email Finder & Verifier (invaluable_rondeau/corporate-email-finder-verifier).
• Need high-volume MX verification up to 50,000 emails at $0.001/email? Use Bulk Email Verifier (invaluable_rondeau/email-verifier-bulk).
• Need SPF / DMARC / DKIM / MX provider security auditing across domains? Use B2B Domain Email Security & Deliverability Auditor (invaluable_rondeau/b2b-domain-email-security-auditor).

Input

{
  "emails": [
    "person@company.com",
    "support@gmail.com",
    "alerts@mailinator.com",
    "not-an-email"
  ],
  "timeoutMs": 1500
}

emails accepts an array or a comma/newline-delimited string through the API. Up to 1,000 unique addresses are accepted per run. Case-insensitive duplicates are emitted once and are not processed twice.

Output

Each row includes email, normalized, domain, isValidSyntax, hasMx, isDisposable, isRoleBased, isFreeProvider, score, decision, reasonCodes, sourceChecks, checkStatus, and checkedAt.

score is a pre-send quality signal, not a probability. checkStatus: partial means DNS could not be resolved in time; that row is returned as review, not as a clean pass.

Pricing

The pay-per-event price is $0.01 per saved risk decision (email-risk-scored). A 1,000-address run is at most $10 before any account-level maximum-charge setting. Duplicate inputs are collapsed before processing. A Dataset row is saved before the charge is attempted. Failed processing is not charged.

Example: 10,000 scored addresses = approximately $100 in Actor charges.

Quick start

1. Run 10–100 addresses first and inspect the Dataset.
2. Keep review rows out of automated sending until a human or downstream policy decides.
3. For recurring hygiene, create an Apify Schedule for the same list and inspect the new Dataset after each run.

Privacy and safety

Only provide addresses you are authorized to process. The Actor does not enrich, discover, or send to addresses. It stores the input address and derived DNS/list signals in the Dataset so you can audit the decision. The built-in lists are intentionally small and are not complete.

  }
}

2. Synchronous HTTP Webhook (n8n, Make, Clay, Zapier, cURL)

Call the synchronous dataset endpoint to get clean JSON items in a single HTTP request:

curl -X POST "https://api.apify.com/v2/acts/invaluable_rondeau~b2b-email-deliverability-risk-gate/run-sync-get-dataset-items?token=$APIFY_TOKEN&memory=256&clean=true" \
