🧹 B2B Lead List Cleaner

Turn a messy lead list into clean, deduplicated, deliverable records. Normalizes emails, flags role/disposable addresses, verifies MX, and marks duplicates — an enrichment add-on for any lead-gen workflow.

⚡ What you get

Your original fields, plus: emailNormalized, domain, validSyntax, roleAccount, disposable, mxValid, isDuplicate, deliverable, issues[].

🎯 Use cases

1. Clean exported lead lists before importing to a CRM
2. Cut bounce rates by dropping invalid/role/disposable emails
3. Dedupe merged lists from multiple sources
4. Pre-flight a list before paid enrichment/outreach

🚀 Sample inputs

{ "leads": [{"email":"Jane.Doe@Stripe.com","company":"Stripe"}, {"email":"info@stripe.com"}, {"email":"jane.doe@stripe.com"}], "dedupeBy":"email", "verifyMx":true }

{ "leads": ["a@acme.com","b@acme.com"], "dedupeBy":"domain" }

📦 Sample output

{ "email":"Jane.Doe@Stripe.com", "company":"Stripe", "emailNormalized":"jane.doe@stripe.com", "domain":"stripe.com", "validSyntax":true, "roleAccount":false, "disposable":false, "mxValid":true, "isDuplicate":false, "deliverable":true, "issues":[] }

📊 Sample Output

🛠 How it works

1. Normalize — lowercases/trims emails, extracts domain.
2. Flag — role accounts, disposable domains, invalid syntax.
3. Verify — checks each domain has an MX record (DNS-over-HTTPS).
4. Dedupe — by email, domain, or whole row.
5. Score — deliverable = valid syntax + not disposable + MX present.

⚖️ Legal & data sources

Operates on the list you provide; the only external call is a public DNS MX lookup (DNS-over-HTTPS). No login, identified User-Agent.

❓ FAQ

Does it send email? No — MX is a DNS check, not an SMTP probe (see Email Verification for SMTP). Dedupe options? email, domain, or whole row. Keeps my fields? Yes — your input fields pass through untouched. What's "deliverable"? Valid syntax + non-disposable + MX present. Role accounts? Flagged (info@, sales@, …), not removed. Fresh MX? Live DNS at run time.

🆘 Troubleshooting

• Everything mxValid=null — verifyMx disabled or DNS unreachable.
• Unexpected duplicates — switch dedupeBy (domain vs email).
• Valid emails flagged — check for role/disposable patterns in issues.
• Want SMTP-level checks — use the Email Verification actor.
