Email Domain Checker

Check emails or domains in bulk: MX records, mail provider (Google/Microsoft...), SPF, DMARC policy, disposable and free-provider flags. Clean lead lists before sending, without mailbox probing.

How it works

Uses DNS lookups (DNS-over-HTTPS via Google and Cloudflare public resolvers) and the community disposable-email-domains blocklist (CC0). It does not connect to mail servers or verify individual mailboxes, so it's fast and won't get your IP blacklisted.

Output

input, domain, syntaxValid, hasMx, mailProvider, spf, dmarcPolicy, disposable, freeProvider, deliverable

Pricing (pay-per-event)

• email-checked: $0.0005 per result ($0.5 / 1,000). Platform usage is included; you pay only for results.

Example input

{
  "emails": [
    "info@apify.com",
    "someone@gmail.com",
    "example.co.uk"
  ]
}

Example output

{
  "input": "info@apify.com",
  "domain": "apify.com",
  "syntaxValid": true,
  "hasMx": true,
  "mailProvider": "Google Workspace",

Domain-level signals only, with no guarantee that a mailbox exists. Use it responsibly and follow anti-spam laws (PECR, CAN-SPAM, GDPR).

Use in Clay, Zapier, Make, n8n, Pipedream, Power Automate or Activepieces

All of them connect to Apify through their official Apify integrations, using your own Apify account: an API token from Apify Console > Settings > API & Integrations, or Apify sign-in for Power Automate. Runs bill to your Apify account at this Actor's pay-per-event price.

• Clay: save this Actor's input as an Apify task and copy it as JSON. In your Clay table, add the Run Apify Actor enrichment, choose it and paste the JSON into Input Data, mapping Clay columns into the fields. To pull a finished run into a new table, use the Import data from Apify Actor source.
• Zapier: use the Apify Run Actor action, or the Finished Actor run trigger followed by Fetch dataset items. Synchronous runs in Zapier stop after 30 seconds, so use the trigger for big batches.
• Make: add the Apify Run an Actor module with Run synchronously set to Yes, then Get Dataset Items with the run's dataset ID. For longer runs, use the Watch Actor Runs trigger.
• n8n: install the Apify node (@apify/n8n-nodes-apify, or search "Apify" on n8n Cloud) and use Run an Actor and get dataset.
• Pipedream: add the Apify app's Run Actor action, or Run Task Synchronously on one of this Actor's public example tasks (or your own saved task) to get the dataset items back in one step. For big batches, start from the New Finished Actor Run or New Finished Task Run trigger, then Get Dataset Items.
• Power Automate: add the Apify connector (a premium connector, currently in preview) and sign in with your Apify account. Use Run Actor with Enter custom value set to sterlingverify/email-domain-checker and paste the input as JSON, then Get dataset items with the run's default dataset ID. For big batches, start the flow from the Actor run finished trigger instead.
• Activepieces: add the Apify piece and use Run Actor, or Run Task on one of this Actor's public example tasks (or your own saved task), then Get Dataset Items. For scheduled or big batches, use the Watch Actor Runs or Watch Task Runs trigger.
• Google Drive / Sheets: add Apify's Upload results to GDrive integration to a scheduled task to drop each run's CSV or XLSX into your team's Drive, or chain the Google Sheets Import & Export actor to append rows to a sheet.
• Slack alerts: add Apify's Slack integration to a scheduled task to post each run's results to your team channel, or start a check from Slack with /apify call and your task ID.
• Any HTTP tool or script: send one request and get the results back as JSON. Runs must finish within 5 minutes.

curl -X POST "https://api.apify.com/v2/acts/sterlingverify~email-domain-checker/run-sync-get-dataset-items" \

FAQ

Does it send emails to verify addresses? No. It checks the domain with DNS only (MX, SPF, DMARC) plus disposable and free-provider lists, so nothing is sent and no mailbox is contacted.

Can it detect disposable or temporary emails? Yes, each row flags disposable/temporary domains and free webmail (e.g. consumer mailbox providers).

What is it good for? Lead list cleaning, signup and merchant onboarding fraud checks, DMARC/SPF audits and email deliverability checks.
