Bad data is expensive. Sales teams waste time on invalid contacts. Marketing sends campaigns to wrong segments. Lead scoring fails because inputs are garbage. The estimated cost of poor data quality is 15-25% of revenue for most organizations.
This guide covers how to implement data quality management that keeps your GTM operations running on reliable data.
The Cost of Bad Data #
Quality Problem Categories
| Problem | Example | Impact |
|---|---|---|
| Incomplete | Missing phone numbers | Can’t reach prospects |
| Inaccurate | Wrong email addresses | Bounced campaigns, deliverability |
| Inconsistent | ”US” vs “USA” vs “United States” | Broken segmentation |
| Duplicate | Same account twice | Wasted effort, confusion |
| Stale | Job changes not updated | Wasted outreach |
Business Impact
- Sales productivity: 27% of sales time wasted on bad data
- Marketing effectiveness: 40% of leads have data quality issues
- Customer experience: 34% of customers affected by data errors
- Decision quality: Strategies built on incomplete picture
Data Quality Dimensions #
The Six Pillars
1. Accuracy Data correctly represents reality.
- Email addresses are valid
- Company names are correct
- Numbers are factual
2. Completeness All required fields are populated.
- No missing critical fields
- Rich enough for use cases
- Gap analysis possible
3. Consistency Data follows standard formats.
- Same values mean same things
- Formats are normalized
- Categories are standardized
4. Timeliness Data is sufficiently current.
- Updates happen quickly
- Staleness is tracked
- Refresh cycles are appropriate
5. Uniqueness No unnecessary duplicates.
- One record per entity
- Duplicates identified and merged
- Sources deduplicated
6. Validity Data conforms to rules.
- Formats are valid
- Values are within ranges
- Relationships are logical
Building a Quality Framework #
Step 1: Define Quality Standards
What does “good data” look like for your organization?
Critical Fields Definition
| Entity | Critical Fields | Quality Requirements |
|---|---|---|
| Account | Domain, Name, Industry, Size | 100% populated, validated |
| Contact | Email, Name, Title | 100% populated, verified |
| Opportunity | Amount, Stage, Close Date | 100% populated, logical |
Quality Rules
| Field | Validation Rule | Notes |
|---|---|---|
| Must match email format regex | e.g., user@example.com | |
| Domain must be valid | Public or company domains only | |
| Not a known spam domain | Use a denylist | |
| Verified deliverable (for outreach) | Via real-time verification | |
| Company Size | Must be numeric | Only numbers accepted |
| Must be > 0 | Reject zero or negative values | |
| Realistic for industry | Fits expected range per industry | |
| Updated within 12 months | Recent data, not outdated | |
| Phone Number | Must match phone format | E.g., +1-555-123-4567 |
| Country code included | International format required | |
| Area code valid | Checked for region correctness | |
| HLR verified (for calling) | Home Location Register check |
Step 2: Measure Current State
Audit your existing data:
Quality Scorecard
| Dimension | Metric | Current | Target |
|---|---|---|---|
| Completeness | % required fields populated | 72% | 95% |
| Accuracy | % emails deliverable | 85% | 98% |
| Consistency | % standardized values | 60% | 90% |
| Timeliness | % data < 6 months old | 65% | 85% |
| Uniqueness | Duplicate rate | 8% | < 2% |
| Validity | % passing validation | 78% | 95% |
Step 3: Identify Root Causes
Where does bad data come from?
Entry Points
- Manual data entry errors
- Form submissions with fake data
- Import errors
- Integration sync issues
- Data decay over time
Process Gaps
- No validation at entry
- No verification processes
- No refresh schedules
- No deduplication
- No ownership
Step 4: Implement Prevention
Stop bad data at the source:
Entry Validation
- Form field validation
- Real-time email verification
- Required field enforcement
- Format standardization
Import Controls
- Pre-import validation
- Duplicate checking
- Mapping verification
- Error reporting
Integration Monitoring
- Sync validation rules
- Error alerting
- Data transformation logging
- Schema change detection
Step 5: Implement Detection
Find problems in existing data:
Automated Monitoring
Daily Quality Checks:
☑ Email deliverability scan
☑ Duplicate detection
☑ Completeness audit
☑ Anomaly detection
☑ Freshness check
Weekly Quality Checks:
☑ Cross-system consistency
☑ Validation rule compliance
☑ Trend analysis
☑ Quality score calculation
Step 6: Implement Correction
Fix problems when found:
Automated Correction
- Standardize formats automatically
- Merge clear duplicates
- Update from trusted sources
- Enrich missing fields
Manual Correction
- Review flagged records
- Resolve uncertain merges
- Research unclear data
- Update special cases
Quality Processes #
Continuous Quality
Real-Time Validation
New record enters system
→ Validate format and completeness
→ Check for duplicates
→ Verify email/phone
→ Standardize values
→ Score quality
→ Flag or accept
Periodic Refresh

Duplicate Management
Detection Rules
Account Duplicate Rules:

Ownership Clarity
Every data element should have an owner responsible for quality.
Automation First
Automate detection and correction where possible.
Continuous Improvement
Quality is a process, not a project. Measure and improve continuously.
Business Alignment
Focus quality efforts on data that impacts business outcomes.

Key Takeaways #
- Data quality impacts every downstream process: scoring, routing, personalization, and analytics all degrade when data quality is poor
- Six quality dimensions: accuracy, completeness, consistency, timeliness, validity, and uniqueness—measure and track each
- Prevention beats remediation: build quality checks at data entry points rather than cleaning up afterward
- Quality scores enable prioritization: assign quality scores to records so sales knows which data to trust
- Continuous monitoring required: data decays over time—job changes, company growth, email bounces—build automated detection
