Email Deliverability & DNS Auth Checker — Bulk MX / SPF / DMARC / DKIM

Check a whole list of domains for email setup and authentication in one run — entirely over DNS, so it's fast, never blocked, and low-maintenance. One JSON row per domain with a deliverability score and verdict.

Great for email-list hygiene, deliverability audits, lead-list scoring, and security posture checks across many domains at once.

What you get per domain

Check	Fields
MX	`has_mx`, `mx_hosts`, `mx_provider` (Google Workspace / Microsoft 365 / Zoho / SES / Tencent / Alibaba / …)
SPF	`spf_found`, `spf_record`, `spf_qualifier` (`-all` / `~all` / `?all`)
DMARC	`dmarc_found`, `dmarc_policy` (`none` / `quarantine` / `reject`)
DKIM	`dkim_selectors_found` (which common selectors publish a key)
Verdict	`auth_score` (x/5), `verdict` (strong / partial / weak), `looks_disposable`

Input

{ "domains": ["stripe.com", "user@acme.com", "https://globex.com"], "dkimSelectors": ["google", "default", "selector1", "k1"] }

Email addresses and URLs are reduced to the domain. Leave domains empty to run the built-in sample.

Output (one item per domain)

{
  "domain": "github.com",
  "has_mx": true,
  "mx_provider": "Google Workspace",
  "spf_found": true, "spf_qualifier": "~all",
  "dmarc_found": true, "dmarc_policy": "reject",
  "dkim_selectors_found": ["google"],
  "auth_score": "5/5", "verdict": "strong",
  "looks_disposable": false
}

Export as JSON/CSV/Excel or pull via the Apify API.

Why DNS-only

It reads MX, SPF/TXT, _dmarc, and <selector>._domainkey records — no SMTP probing (which mail servers block) and no scraping. That makes results stable and the Actor low-maintenance. Note: it verifies a domain's email authentication setup, not whether a specific mailbox exists.

Pricing

Pay per result: $0.01 per domain checked. No rental, no subscription.
