The Problem

Your contact database is a liability when it is dirty. Marketing sends campaigns to dead addresses and tanks sender reputation. Sales calls disconnected numbers and loses selling time. RevOps builds routing rules on incorrect job titles, sending enterprise prospects to SMB reps. The root cause is rarely a single bad import — it is the gradual accumulation of entropy from dozens of data sources, each with different formatting standards and accuracy levels.

How Cleanlist Solves This

Cleanlist's contact cleaning goes beyond removing invalid records. It standardizes inconsistent data across all your sources: normalizing name capitalization, standardizing phone formats, canonicalizing company names, deduplicating across fuzzy-matched fields, and removing contacts that are unreachable, unengaged, or compliance-risky. The result is a uniform, trustworthy contact database that every team can rely on.

Inconsistent Job Titles Are the Silent Killer of Lead Routing Accuracy

23%of leads are misrouted due to non-standard job titles

Lead routing rules in most CRMs depend on job title fields to determine which rep or team gets the lead. But job titles in B2B are wildly inconsistent: 'VP of Sales,' 'Vice President, Sales,' 'VP Sales & Partnerships,' 'Head of Revenue,' and 'Chief Revenue Officer' may all describe the same seniority level but match different routing rules. Cleanlist's analysis of 2.3 million contact records from 90 customer databases found that 23% of contacts had job titles that would trigger incorrect routing in a typical round-robin or territory-based assignment system. The fix is title normalization — mapping all variations to a standardized seniority-function matrix (e.g., VP-level / Sales function). After normalization, routing accuracy improved to 94% for customers who implemented the cleaned title data in their CRM routing logic.

How It Works

1

Import Contacts from Any Source

Connect your CRM, upload spreadsheets from different teams, or point Cleanlist at multiple data sources simultaneously. The tool reconciles records across sources and identifies where the same contact appears with conflicting data.

2

Data Profiling & Quality Score

Every record is scored on completeness (how many fields are filled), accuracy (how many fields pass validation), and freshness (how recently the data was confirmed). A summary histogram shows the distribution of quality scores across your database.

3

Standardization & Formatting

Names are capitalized consistently (handling McDonalds, O'Brien, van der Berg). Phone numbers are formatted to E.164. Addresses are parsed into structured components. Job titles are mapped to a canonical hierarchy for consistent segmentation.

4

Deduplication

Fuzzy matching identifies duplicate contacts across variations: nickname-to-formal-name mapping (Bob/Robert, Bill/William), company name variants (IBM/International Business Machines), and email domain aliases (microsoft.com/outlook.com for internal accounts).

5

Validation & Enrichment

Invalid emails and disconnected phones are flagged. Missing fields are optionally filled through waterfall enrichment. Contacts who have changed jobs are identified with updated employment information.

6

Export Clean Dataset

Download your cleaned contacts with all original columns preserved plus new quality-indicator columns. Suppressed contacts (invalid, duplicate, compliance-risk) are exported separately for your records and audit trail.
