Expert B2B contact data audit framework for RevOps, GTM Engineering, and Sales Operations. Use when running a data quality audit on a CRM (HubSpot, Salesforce, Pipedrive, Close, Attio), scoring a contact data layer across 10 dimensions (coverage, accuracy, freshness, cost, governance, and more), answering benchmark questions on email accuracy, bounce rates, mobile connect rates, or data decay, or validating provider claims (Apollo, ZoomInfo, Cognism, Clay, BetterContact). Triggers on: audit our data, data quality check, is our data the bottleneck, email accuracy benchmark, verified email rate, cost per usable contact, mobile connect rate, data decay, CRM hygiene, ZoomInfo vs Cognism, waterfall vs single source, RevOps audit, data layer for AI agents. Run before a GTM Alpha Playbook or Clay build. Do NOT use for list building (use gt-list-building), Clay workflow setup (use gt-clay), HubSpot admin without data quality scope (use gt-hubspot-admin), or cold email copywriting (use gt-cold-email).

GT Data Audit
A 10-dimension audit framework for B2B contact data quality. Produces a 0 to 10 score across coverage, accuracy, freshness, cost, governance, and 5 other dimensions. Built for RevOps leaders, GTM Engineers, and Sales Operations at B2B SaaS past $10M ARR.
The full audit takes 3 to 5 hours of hands-on work for the person running it. The skill covers all 10 dimensions in order, scores each one against a pass benchmark, and returns a single number plus a prioritized fix list.
Two operating modes
Client-facing mode (default) For lead magnet downloads, prospect deliverables, and external sharing. Anyone can run this audit on their own stack. Voice is operator-real and jargon-free with no GT-internal references. Output formats: Notion page, 1-page PDF, scorecard.
GT-internal mode For the GT team running an audit on a live client portal. Adds internal context: client tier, engagement type, link to the GTM Alpha Playbook, deliverable templates, and a recommended next-step engagement based on the score.
Default to client-facing mode. Switch to GT-internal mode ONLY when the prompt contains an explicit marker:
- "for [client name]"
- "Velocity engagement" / "GTM Alpha engagement" / "GTM Alpha"
- "before GTM Alpha delivery"
- "internal audit" / "team mode"
If it is unclear which mode applies, ask once: "Is this for external sharing as a lead magnet, or internal use by the GT team running an audit on a client?"
When to fire
Fire when the user's message contains any of these intents:
- "audit our data" / "data quality check" / "data audit"
- "is our data the bottleneck" / "data layer for AI agents" / "AI agent data foundation"
- "email accuracy benchmark" / "what is a good bounce rate" / "verified email rate"
- "cost per usable contact" / "cost per credit" / "data provider pricing"
- "mobile connect rate" / "phone data accuracy" / "cold call connect benchmark"
- "data refresh cycle" / "how often refresh data" / "data decay"
- "CRM data audit" / "CRM hygiene" / "data governance for GTM"
- "validate our data provider" / "is Apollo enough" / "ZoomInfo vs Cognism"
- "waterfall enrichment vs single source" / "AI routing for enrichment"
- "RevOps audit" / "data scorecard" / "data foundation"
- "BetterContact audit" / "BetterContact partnership"
Also fire automatically when:
- A GTM Alpha Playbook is being prepped for delivery (audit is a precondition)
- A Clay implementation is being scoped (validate data before build)
- A prospect downloads the data audit lead magnet and books a call
Do NOT fire when:
- The user wants to BUILD a list from scratch ↳ defer to
gt-list-building - The user wants Clay workflow help unrelated to validation ↳ defer to
gt-clay - The user wants HubSpot portal admin work unrelated to data quality ↳ defer to
gt-hubspot-admin - The user wants cold email copy or sequences ↳ defer to
gt-cold-email

The 10 dimensions
Every audit covers all 10 in order. Each dimension has a question, why it matters, audit steps, a pass benchmark, and a fix. Score 1 point per pass benchmark hit. Maximum 10.
Dimension 1: Coverage
Question: Can you actually find the contacts you need on your target list?
Why it matters: The average provider delivers only 50% accuracy on independent tests (Landbase 2026). Single-source providers return 400 to 600 usable matches per 1,000 queried on a tight ICP slice. The rest are misattributed titles, generic info@ inboxes, or contacts with no email.
Audit steps:
- Pick one tight ICP slice (one role, one company tier, one geo). Example: "VP of Sales at B2B SaaS $25M to $100M ARR in North America"
- Run the same exact query through 4 providers (Apollo, ZoomInfo, Cognism, Clay waterfall)
- Count how many contacts each provider returns for the same query
- Count how many have valid corporate email vs catch-all vs missing
- Count how many have mobile direct dial vs office line vs missing
Pass benchmark:
- ✅ Strong: 70%+ match rate on a tight ICP slice
- 🟡 Acceptable: 50% to 69% (waterfall enrichment needed to fill gaps)
- ❌ Fail: Under 50% (single provider is leaving half your TAM on the table)
Fix: Switch to multi-provider waterfall. Waterfall enrichment hits 85% to 95% find rates versus 50% to 60% for single-source (DealSignal 2026).
Tools: Single-source: Apollo, ZoomInfo, Cognism, Lusha. Waterfall: BetterContact, Clay (with provider stack), Cleanlist, Datagma.
Dimension 2: Email Accuracy
Question: Are the emails in your list actually deliverable?
Why it matters: A "verified" list can sit at 38% bounce on the first campaign send (SparkDBI 2026). Validity's 2025 benchmark shows senders with bounce rates above 5% see inbox placement drop by 20 percentage points. Once your sending domain is flagged, every email you send is at risk, including replies to existing customers.
Audit steps:
- Take 200 contacts from your CRM at random
- Run them through 3 independent verifiers (ZeroBounce, Million Verifier, Prospeo)
- Count how many come back valid vs catch-all vs risky vs invalid
- Compare each verifier's score against the others (catches verifier disagreement)
- Send a small test sequence (50 contacts) and measure actual bounce rate
Pass benchmark:
- ✅ Strong: 90%+ valid rate on a well-defined ICP list
- 🟡 Acceptable: 80% to 89% (requires active list hygiene)
- ❌ Fail: Under 80% (disqualify the data source)
- Real-world bounce rate target: under 1% (Validity 2025)
- Hard bounce above 2% triggers spam filters at Google and Microsoft
Fix: Add real-time verification at point of capture (form, CSV upload). Verify any list older than 30 days before send. Set up bounce monitoring as a daily metric.
Tools: ZeroBounce, Million Verifier, NeverBounce, BriteVerify, Prospeo, Mailfloss.
Dimension 3: Phone and Mobile Connect Quality
Question: What percentage of your phone numbers actually reach a live human?
Why it matters: US B2B SDRs lose 35% of their day to manual dialing and dead-ring time (Bridge Group 2026). The average cold connect rate sits at 3% to 10%. Top teams with verified mobile direct-dials hit 18% to 22%, which is 2x the baseline (Cognism State of Cold Calling 2026, 200,000 calls analyzed).
Audit steps:
- Pull 100 phone numbers from your CRM
- Categorize each: mobile direct, office line, switchboard, missing
- Dial all 100 and log: live connect, voicemail, dead ring, disconnected
- Calculate connect rate by source (which providers gave you mobile vs office)
- Check whether your data provider distinguishes mobile from office at point of enrichment
Pass benchmark:
- ✅ Strong: 60%+ mobile direct dial coverage on a US list
- 🟡 Acceptable: 30% to 59% (this gap is your highest-leverage fix)
- ❌ Fail: Under 30% (you are paying for numbers that do not connect)
- Connect rate target: 18% to 22% on verified mobile, 8% to 12% on generic
Fix: Switch to mobile-first phone providers. Verified mobile is the single biggest connect rate lever (Prospeo 2026). Mobile numbers connect at 45% higher rates than non-mobile.
Tools: Mobile-first: Cognism, Lusha, Nooks. Mixed: ZoomInfo, Apollo.
Dimension 4: Data Freshness and Recency
Question: How old is the data sitting in your CRM right now?
Why it matters: B2B contact data decays at 2.1% per month, compounding to 22% to 30% annually (Dun & Bradstreet). A list that was 95% accurate 12 months ago is likely sitting at 65% to 70% accuracy today. 23% to 30% of emails go stale per year. 18% of phone numbers change. 15% to 20% of professionals change employers.
Audit steps:
- Look at the "last enriched" or "last updated" date on 100 CRM contacts
- Calculate what percentage was last touched more than 6 months ago, and more than 12 months ago
- Run those stale contacts through fresh enrichment
- Count how many are now outdated (job change, email change, company change)
- Look at your provider's claimed refresh cycle: weekly, monthly, quarterly, or "as needed"
Pass benchmark:
- ✅ Strong: 90%+ of CRM contacts refreshed in the last 90 days
- 🟡 Acceptable: 60% to 89% (set up automated refresh)
- ❌ Fail: Under 60% (data layer decaying faster than you refresh)
- Provider refresh cadence: weekly (top tier) or monthly minimum
Fix: Set up automated re-enrichment on a 30-day cycle for active sequences and a 90-day cycle for the full CRM. Trigger re-verification on any contact that bounces or gets a "no longer with company" reply.
Tools: Clay (auto-refresh workflows), HubSpot Operations Hub, Salesforce Data Cloud, RingLead, Cloudingo.
Dimension 5: Cost Per Usable Contact
Question: What does each contact actually cost, after you strip out the unusable ones?
Why it matters: Listed cost is not real cost. If a provider charges $0.50 per record but 40% bounce, your real cost per usable contact is $0.83. Credit-based providers (Cleanlist, People Data Labs) typically save 40% to 60% versus seat-based annual contracts (ZoomInfo, Cognism) for the same volume (Cleanlist 1,000-record benchmark 2026). Pricing across 15 tested providers ranges from $0.01 to $2.50 per record.
Audit steps:
- Pull last quarter spend on each data tool (annual contract divided by 4, plus any usage fees)
- Pull the total contacts enriched or pulled in that quarter
- Calculate raw cost per record (spend divided by total contacts)
- Apply your verified-valid rate from Dimension 2 to get real cost per usable contact
- Compare across providers. Look for hidden overage charges, seat caps, export limits
Pass benchmark:
- ✅ Strong: Under $0.30 per usable contact on a high-volume waterfall
- 🟡 Acceptable: $0.30 to $0.80 per usable contact for mid-volume
- ❌ Fail: Above $0.80 per usable contact (audit your provider mix)
- Credit-based is typically 40% to 60% cheaper than seat-based for the same volume
Fix: Audit which providers carry the load on which lead types. Drop overlap. Move from seat-based to credit-based where volume justifies.
Tools: Credit-based: Cleanlist, People Data Labs, BetterContact, Datagma. Seat-based: ZoomInfo, Cognism, Apollo (annual).
Dimension 6: Enrichment Method and Validation Layer
Question: Is your enrichment single-source, waterfall, or AI-routed?
Why it matters: Single-source databases deliver 50% to 60% find rates. Multi-source waterfalls hit 85% to 95% (DealSignal 2026). AI-routed waterfalls (dynamic provider sequencing based on lead type) outperform static waterfalls by another 5% to 15%, depending on ICP fit.
Audit steps:
- Map how your enrichment currently flows (one provider in CRM, chained waterfall in Clay/n8n, or AI-routed system)
- For a sample of 100 contacts, record which provider returned the winning data point per field (email, phone, title)
- Calculate which provider is doing the heaviest lifting, and which fire often but rarely win
- Check whether the order of providers is static or changes based on region, seniority, or industry
- Check whether your enrichment layer supports fallback chains, retry logic, per-field verification
Pass benchmark:
- ✅ Strong: Multi-source waterfall + AI routing (best in class)
- 🟡 Acceptable: Multi-source waterfall (static order)
- ❌ Fail: Single-source only (leaving 30 to 45 percentage points of find rate on the table)
Fix: Move to a multi-source waterfall. Add dynamic routing logic. Some leads need US-mobile providers first, others need EU-compliant providers first. Track which providers win and adjust the order quarterly.
Tools: Waterfall builders: Clay, n8n, Make, BetterContact. AI routing: BetterContact, Findymail, Datagma.
Dimension 7: CRM Hygiene and Format
Question: Is the data in your CRM structured so AI agents and workflows can actually use it?
Why it matters: 70% of CRM systems contain outdated, incomplete, or inaccurate information (Landbase 2026). Even if source data is clean, the way it sits in the CRM determines whether downstream automations work. Duplicate companies create fragmented account views. Inconsistent country fields ("US" vs "USA" vs "United States") break segmentation. Wrong title casing breaks lead scoring.
Audit steps:
- Run a deduplication scan on companies and contacts. Count duplicates
- Check title formatting. Are titles standardized or free-text? Example: "VP Sales" vs "VP, Sales" vs "Vice President of Sales"
- Check country, state, and city fields for inconsistencies
- Check email and phone number formatting normalization
- Check which fields are required at point of creation, and which are optional
Pass benchmark:
- ✅ Strong: Under 2% duplicate rate on companies
- ✅ Strong: Standardized title taxonomy in use
- ✅ Strong: Country, state, city normalized in one format
- ❌ Fail: Any of the above missing (downstream automation will misfire)
Fix: Run Salesforce or HubSpot native deduplication first. For larger databases, use RingLead or Cloudingo. Set up validation rules at point of capture. Apply a title-normalization workflow on import.
Tools: Native: Salesforce Duplicate Management, HubSpot Operations Hub. Dedicated: RingLead, Cloudingo, Insycle, DemandTools.
Dimension 8: Data Governance and Ownership
Question: Who owns this and how often is it audited?
Why it matters: 44% of teams report more than 10% annual revenue impact from CRM data decay (Landbase 2026). The decay is not the surprising part. Most teams have no named owner for data quality. Without a single accountable person, the data layer drifts back to broken within 90 days of any cleanup.
Audit steps:
- Name the single accountable person for data quality (title and email)
- Map who has write access to the CRM. Are vendors, partners, or anyone outside the company on this list
- Document the data audit cadence (daily, weekly, monthly, quarterly, never)
- Document the data sources allowed. Which providers are approved. Which are banned
- Document field ownership. Who decides what "lead status" means. Who owns lifecycle stage definitions
Pass benchmark:
- ✅ Strong: One named accountable person
- ✅ Strong: Monthly audit cadence
- ✅ Strong: Written rules for data sources, field definitions, write access
- ❌ Fail: Any of the above missing (the layer will drift back within 90 days)
Fix: Pick one person (RevOps lead or Head of GTM Engineering is the typical fit). Set a 30-minute monthly audit on the calendar. Write a one-page rules doc. Pin it in the team workspace.
Tools: HubSpot Operations Hub, Salesforce Flow, n8n (governance triggers).
Dimension 9: Compliance and Opt-Out Tracking
Question: Are you allowed to contact each person in your database?
Why it matters: GDPR (EU), CCPA (California), CAN-SPAM (US), CASL (Canada), and PECR (UK) all have different opt-out and consent rules. A single opt-out that fails to propagate across tools is a compliance risk. Spam complaint rate benchmark for 2025 is 0.04% to 0.06% (B2B average). Above 0.3% is the critical threshold that triggers Gmail and Outlook filters.
Audit steps:
- Pull every contact that has unsubscribed in the last 12 months. Verify they are suppressed in every outbound tool (Lemlist, EmailBison, HubSpot, Salesforce)
- Check whether you have a single source of truth for unsubscribes, or whether it is tracked per tool
- For EU contacts, check whether you have a documented legal basis (legitimate interest, consent, or contract) for cold outreach
- Check whether you honor opt-out within 10 business days (CAN-SPAM) and immediately for EU
- Check your spam complaint rate. Is it tracked. What is the rolling 30-day number
Pass benchmark:
- ✅ Strong: 100% suppression propagation across tools (required)
- ✅ Strong: Spam complaint rate under 0.1%
- ✅ Strong: Documented legal basis per region (required)
- ✅ Strong: Single source of truth for opt-outs
- ❌ Fail: Any of the above missing (you are one audit away from a compliance event)
Fix: Centralize opt-out tracking in one tool, typically the CRM. Use webhooks or native sync to push opt-outs to every outbound tool within minutes. Document legal basis per region. Set a 0.1% spam complaint alert threshold.
Tools: Suppression tracking: HubSpot, Salesforce Marketing Cloud, Customer.io. Spam monitoring: Glock Apps, Mailgun, Litmus.
Dimension 10: Measurement and the 3 Numbers That Matter
Question: What 3 numbers should you track after every audit?
Why it matters: You can audit data quality once and feel good about it. Without ongoing measurement, the layer decays 22% to 30% per year and you are back where you started. The 3 numbers below are the minimum viable scorecard for any GTM data layer.
The 3 numbers:
Number 1: Verified email rate ↳ Target: 90%+ on active lists ↳ Pull from your verifier. Calculate weekly ↳ Trigger re-verification on any list below 90%
Number 2: Mobile connect rate ↳ Target: 18% to 22% on verified mobile data ↳ Pull from your dialer. Calculate weekly ↳ Compare against the SDR team actual connect rate. If the gap is larger than 5 points, data is the bottleneck
Number 3: Cost per usable contact ↳ Target depends on volume and ICP, but track quarter over quarter ↳ Total spend across all providers, divided by total verified-and-deliverable contacts added to active sequences ↳ Drop providers that drift above your threshold
Pass benchmark:
- ✅ Strong: All 3 numbers tracked weekly or monthly
- ✅ Strong: Numbers visible to RevOps, GTM Engineering, and Sales leadership
- ✅ Best in class: Action thresholds defined (example: below 85% verified email = pause campaign)
- ❌ Fail: No ongoing measurement (the layer will decay back within 6 months)
Fix: Build a one-tab dashboard. HubSpot reports, Salesforce dashboards, or a simple Looker or Metabase board. The point is visibility, not perfection.
Scoring
Score 1 point per pass benchmark hit. Maximum 10. Full interpretation and per-band next steps are in resources/scoring.md.
| Score | Interpretation | Priority next step |
|---|---|---|
| 0 to 3 | Data layer is the bottleneck. Every AI agent and workflow built on top of it is degraded | Pick one dimension. Fix it this quarter. Do not try to fix all 10 at once |
| 4 to 6 | Some hygiene but no systematic governance. Decay catches you within 6 months | Audit your provider stack. You are probably paying for overlap |
| 7 to 9 | Strong foundation. Focus on 1 or 2 missing dimensions | Layer AI routing and predictive quality scoring on top |
| 10 | Top 5% data layer. AI agents built on top will actually perform | Maintain monthly audit cadence. Share your playbook with your team |
CRM-specific routing
The 10 dimensions and benchmarks apply identically regardless of CRM. resources/crm-routing.md has light "where to start" guidance for HubSpot, Salesforce, Pipedrive, Close, and Attio. For deep portal work, defer to the dedicated admin skill (gt-hubspot-admin, future gt-salesforce-admin).
Output format
After scoring, deliver the result using one of three templates from resources/audit-template.md:
- Notion full report (client-facing) ↳ the canonical version lives at https://app.notion.com/p/38499b4b2619817f83abeed4b3ebbc37. Re-deliver the content programmatically or point the user to the page
- 1-page PDF executive summary (client-facing, condensed)
- Slack snippet (GT-internal, 3 numbers plus next steps)
In client-facing mode, end with a soft CTA: "If you want help running this audit on your stack, book a call at growthtoday.co/contact."
In GT-internal mode, end with the recommended GT engagement based on score:
- 0 to 3 ↳ Velocity rebuild (data foundation engagement)
- 4 to 6 ↳ GTM Engineering audit plus provider rationalization
- 7 to 9 ↳ AI routing layer plus signal-based plays
- 10 ↳ no rebuild needed, recommend Plays implementation
Voice rules
Apply to every output, both modes:
- No em dashes. Use "to", "and", or periods
- No contractions. "You are" not "you're". "It is" not "it's"
- Banned vocabulary: leverage, unlock, synergy, drive, empower, disrupt, transformative, robust, holistic, paradigm, game-changer
- ↳ arrows only for sub-points. Never → arrows
- Operator-real language, 5th-grade vocabulary where possible
- Specific numbers, never abstractions ("X% lift" not "significantly improve")
- No marketing transitions ("the key insight is...", "what we learned was...")
- No prescriptive "you should" / "you need to". State the principle directly
- Cite sources briefly when using benchmarks ("Validity 2025", "Cognism 2026")
