📩 Email Deliverability Checker

Lead Enrichment Pack — Step 2 of 3 Extract contacts → validate emails → validate phones → hand off to CRM

Validate extracted email addresses before they hit your outreach sequences. After running Contact Details Extractor to pull emails from company pages, feed those addresses here to filter invalid, disposable, and undeliverable addresses — protecting your sender reputation and ensuring only trusted contacts reach your CRM.

Each email gets a 0–100 deliverability score based on RFC syntax validity, live DNS MX record lookup, and disposable provider detection. Sales teams and growth marketers use this actor to clean scraped lists before cold outreach, audit existing CRM records monthly, and gate signups against throwaway addresses.

Lead Enrichment Pack — 3-step workflow

Step	Actor	Job
1	Contact Details Extractor	Scrape public emails, phones, and social links from company pages
2	Email Deliverability Checker ← you are here	Validate emails: syntax, MX records, disposable detection, deliverability score
3	Phone Number Validator	Normalize and validate phone numbers with type detection (mobile / landline / VoIP)

• Sales Outreach Pre-Flight — validate a prospect list before launching a cold email sequence
• CRM Hygiene Audit — bulk-validate up to 1,000 addresses from an existing CRM export

Tips & Limitations

• Run before launching a cold email campaign to verify your sending domain is configured correctly.
• DMARC policy reject is the strongest protection against spoofing.
• Audit your customers' domains to upsell deliverability consulting services.
• Combine with Phone Validator for full lead-data quality scoring.

FAQ

Does this catch typos like gmial.com?

It checks MX validity — gmial.com has no MX records, so it's flagged invalid. Use the score field for confidence.

What score should I trust?

90+ is safe for sending. 70-90 is risky. Below 70 should be discarded or double opt-in'd.

Does it check if the inbox exists?

No — that requires SMTP handshake which can mark your sender as abusive. Not safe for bulk checking.

How often is the disposable domain list updated?

The embedded list covers 3,000+ known disposable providers. Updated with releases.

Does this verify individual email addresses?

No — domain-level configuration only. Use a dedicated email verification service for per-address checks.

What does dkimPass=true actually mean?

We detected at least one valid DKIM selector (default, google, k1, mail, etc.). It does not guarantee all senders sign correctly.
