Lead Enrichment Confidence Scorer

Score enriched leads on data confidence (0-100) with signal-by-signal explanations, missing field detection, and recommended next actions. Works with any enriched lead dataset.

What does Lead Enrichment Confidence Scorer do?

Lead Enrichment Confidence Scorer takes enriched lead data and produces a confidence score (0-100) for each lead based on 10 weighted signals. It tells you not just how confident you should be in each lead's data, but why — which signals are strong, which data is missing, and what specific actions to take to improve each lead.

It works with output from Multi-Source Lead Enrichment or any enriched lead dataset that includes company, contact, and source metadata fields.

Use cases

• Sales teams — Prioritize outreach by data quality, not just lead score
• Marketing ops — Identify leads that need additional enrichment before campaigns
• Data quality audits — Score your entire CRM export to find data gaps
• Pipeline hygiene — Filter out low-confidence leads before they enter your pipeline
• Enrichment ROI — Measure how well your enrichment sources are performing

Why use Lead Enrichment Confidence Scorer?

• Transparent scoring — Every score comes with a full signal breakdown
• Actionable recommendations — Specific next steps to improve each lead's confidence
• Weighted signals — 10 signals with weights based on sales impact (verified email = 20pts, company ID = 15pts, etc.)
• Confidence levels — Critical, low, medium, high, very-high for quick triage
• Debug mode — Full per-signal weight breakdown for tuning and analysis
• Works with any data — Accepts loose JSON objects, not tied to a specific enrichment tool

Scoring signals

Signal	Weight	What it measures
Verified email	20	Email present and verification status
Company identified	15	Company name and domain known
Contact name	12	Full contact name available
Job title	10	Role/title or seniority level known
Multi-source	10	Data confirmed by 2+ independent sources
Industry known	8	Industry classification available
Phone available	7	Direct phone number present
LinkedIn profile	7	LinkedIn URL linked
Location data	6	Geography/location known
Company size	5	Headcount or company type known

Total: 100 points possible. Partial scores are awarded (e.g., unverified email = 8/20, one source = 0/10, two sources = 7/10).

Confidence levels

Level	Score range	Meaning
very-high	85-100	Comprehensive, cross-verified data — ready for outreach
high	65-84	Good quality, minor gaps — actionable
medium	45-64	Moderate confidence — enrich further before outreach
low	25-44	Significant gaps — needs additional enrichment
critical	0-24	Very little verified data — requires substantial work

Input parameters

Parameter	Type	Required	Default	Description
leads	object[]	Yes	—	Array of enriched lead objects with company, contact, and enrichment fields
minConfidence	integer	No	0	Only output leads at or above this confidence threshold
includeDebugWeights	boolean	No	true	Include per-signal weight breakdown in output

Tips and best practices

• Use minConfidence: 50 to filter out leads that need too much work before outreach
• The debugWeights array shows exactly how each signal contributed to the score
• Chain with Multi-Source Lead Enrichment: run enrichment first, then pipe the output here
• Use the recommendedActions to build enrichment task lists for your data team
• Leads scoring 85+ are ready for direct outreach without further enrichment

FAQ

All my leads score very low even though they have good data. Check that your lead objects use the expected field names. The scorer looks for specific fields like companyName, domain, contactName, email, emailStatus, sources, sourceCount, industry, phone, linkedinUrl, location, and companySize. Misnamed fields will not be detected.

The minConfidence filter returns no results. If all your leads score below the threshold, the dataset will be empty. Start with minConfidence: 0 to see all scores, then adjust the threshold based on your data.
