Email Deliverability Portfolio Audit API

Audit email deliverability configurations at scale to ensure your outreach actually reaches the inbox. For marketing agencies, IT professionals, and data teams managing massive domain portfolios, manually verifying DNS infrastructure across hundreds of client domains is virtually impossible. This automation tool allows you to run bulk checks for SPF, DKIM, DMARC, MTA-STS, TLS-RPT, and BIMI setups across thousands of urls without building a custom script from scratch.

Protecting your sender reputation means catching misconfigurations before they impact critical business communications. By scheduling recurring daily or weekly runs, your team can track changes in domain health, monitor infrastructure drift over time, and immediately route failures to a webhook remediation queue. Whether you are prepping a cold lead contact list or auditing enterprise portfolios, this checker processes results in highly parallel batches for maximum speed.

The tool relies strictly on public DNS queries rather than web scraping private pages, ensuring complete privacy compliance while you extract vital security details. Output includes structured, developer-friendly JSON data featuring a high-level executive_summary object and detailed remediation_steps. Key fields provided for each domain include mx_record_details, dmarc_policy_status, and strict alignment metrics to help you resolve failures instantly.

Store Quickstart

• Start with store-input.example.json for the smallest useful run: 2 domains in, one executive summary + clean remediation rows out.
• Then move to store-input.templates.json:
  • Starter Quickstart (2 Domains -> Executive Summary + Clean Rows)
  • Portfolio Watch (Recurring Dataset Baseline)
  • Webhook Remediation Queue

Key Features

• 🎯 Lead-qualified extraction — Surfaces contact signals from public profiles with validation flags
• ✅ Deliverability scoring — MX/SPF/DMARC checks produce confidence scores on every record
• 🔄 Bulk processing — Audit thousands of domains/emails per run with parallel verification
• 📊 CRM-ready output — Dataset columns map 1:1 to Salesforce/HubSpot import templates
• 🛡️ Privacy-compliant — Reads public DNS/WHOIS only — no scraping of protected data

Use Cases

Who	Why
Developers	Automate recurring data fetches without building custom scrapers
Data teams	Pipe structured output into analytics warehouses
Ops teams	Monitor changes via webhook alerts
Product managers	Track competitor/market signals without engineering time

Input

Field	Type	Default	Description
domains	array	prefilled	Start with 2-3 domains for the first deliverability baseline. Expand later into larger recurring portfolios while keepin
followRedirects	boolean	true	Follow redirects when checking the main HTTPS endpoint and the MTA-STS policy URL.
checkDkim	boolean	true	Probe a small set of common selectors so the first run catches missing DKIM posture quickly.
dkimSelectors	array	—	Optional custom DKIM selectors to probe instead of the built-in defaults.
checkBimi	boolean	true	Optional branding readiness check. Missing BIMI is treated as an opportunity signal, not a hard failure.
delivery	string	"dataset"	Dataset mode keeps the first run lightweight while still writing the full executive summary to OUTPUT. Webhook mode send
webhookUrl	string	—	Required when delivery=webhook.
snapshotKey	string	"email-deliverability-portfolio-audit"	Reuse the same key when you move from the starter baseline to recurring monitoring so policy changes stay comparable.

Tips & Limitations

• Combine with email-deliverability-checker for full MX+SMTP validation before outreach.
• Use webhook delivery to drop leads into your CRM automation in real-time.
• For ABM campaigns, run weekly against your target list to catch domain changes.
• Low confidence scores (<70) often indicate parked domains — filter before sending outreach.
• This actor is GDPR-safe: no PII is stored, only infrastructure-level signals.

FAQ

Is this GDPR-compliant?

Yes — this actor only processes public infrastructure data (DNS, WHOIS, public website content). No PII is stored.

How accurate is the deliverability score?

Infrastructure-level checks are 95%+ accurate for identifying broken/parked domains. SMTP-level accuracy requires email-deliverability-checker.

Can I use this in a signup form?

The actor is optimized for batch processing, not real-time signup validation. For per-request use, query Apify API directly.

Does this verify if an email actually exists?

This actor checks MX/SPF/DMARC infrastructure. For SMTP-level RCPT TO verification, use email-deliverability-checker.

Can I export to HubSpot/Salesforce?

Yes — use webhook delivery with a Zapier/Make connector, or pull from Dataset API directly.
