TL;DR
- Contact data decays 30-35% per year as people change jobs, companies grow, and phone numbers go stale
- The real cost isn’t just bad data—it’s bounced emails, broken sequences, and wasted rep time on disconnected numbers
- Batch enrichment works for historical cleanup, but real-time enrichment keeps data fresh as it enters your system
- With Lusha, you can automate CRM hygiene so it runs continuously—eliminating the need for dreaded annual cleanup projects
Contact data has a shelf life.
About 30-35% of B2B contact information becomes outdated every year. People change jobs. Companies get acquired. Phone numbers disconnect. Email addresses bounce.
Most teams know this. They also know their CRM is full of stale data. But fixing it feels like a project—export contacts, run enrichment, re-import, repeat next year.
The problem is that by the time you finish the cleanup, the data is already decaying again.
How fast B2B data actually decays
The numbers aren’t theoretical. They’re based on real-world turnover and change patterns:
- Multiple industry sources show B2B data can decay by 30-70% per year, with 30% being the conservative baseline
- Some industries see even higher rates—tech and high-growth sectors can hit 70% annually
Email address decay: 22.5% per year
- Email addresses decay at 22.5% annually on average
- Data showed a 3.6% decay rate in a single month—significantly higher than the historical 1.5-2.0% monthly average
Phone number changes
- Every 30 minutes, 75 phone numbers change globally
Company data changes
- Every 30 minutes: 120 business addresses change, 20 CEOs leave their jobs, and 30 new businesses are formed
If you’re only enriching once a year, you’re working with data that’s 30% wrong by the time you finish—and the decay rate is accelerating.
The real cost of stale data
When bad data seeps into your CRM, it causes your workflows to break down.
- Bounced emails kill sender reputation
- Sequences break mid-cadence
- Reps waste time on dead contacts
- Routing fails on outdated fields
- Reporting becomes unreliable
Batch enrichment vs. real-time enrichment
To keep a CRM healthy, you need a two-pronged approach.
- Batch enrichment: Cleaning historical data
- What it does: Lusha scans your existing CRM database in bulk to update every record with current information.
- When to use it: During an initial CRM cleanup, quarterly refresh cycles, or after importing a legacy lead list.
- The goal: To ensure your “foundational” data is accurate.
- Real-time enrichment: Keeping new data fresh
What it does: Lusha enriches contacts the split-second they are created in your CRM (via form fill, manual add, or CSV import).
- When to use it: Inbound lead capture, demo requests, and webinar registrations.
- The goal: To ensure no “dirty” data ever enters your system in the first place.
How to build a continuous hygiene loop with Lusha
You don’t need a complex integration layer to keep your data fresh. By using Lusha’s native CRM integrations, you can set up a self-healing database.
For new contacts (real-time)
Set Lusha to trigger the moment a new record is created in HubSpot or Salesforce. Lusha instantly populates verified direct dials, job titles, and firmographics. Every new contact enters the system “ready to call.”
For existing contacts (scheduled refresh)
Use Lusha’s enrichment tools to target stale records. You can filter for any contact that hasn’t been updated in 90 days or is missing a direct dial. With one click, Lusha refreshes those records with the latest data from its live database.
For re-engaged leads (signal-based)
If a “lost” lead from two years ago suddenly visits your pricing page or opens an old marketing email, don’t let a rep call them using two-year-old data. Use Lusha to refresh the contact profile the moment they re-engage, ensuring the rep has their current title and phone number.
What to enrich (and when)
Not all fields decay at the same rate. Focus your enrichment budget on what matters most.
High-decay fields (refresh every 90 days):
- Job title
- Company name
- Email address
- Phone number
Medium-decay fields (refresh every 6 months):
- Seniority level
- Department
- Company size (employee count)
Low-decay fields (refresh annually):
- Industry
- Company location (HQ)
Tip: Use engagement as a trigger. If a contact opens an email or books a meeting after 6+ months of silence, refresh their data before your rep reaches out.
Why continuous enrichment beats annual cleanups
Annual cleanup:
- 30% of data is wrong by month 12
- Requires dedicated project time
- Reps work with bad data 11 months of the year
Continuous enrichment:
- New data starts clean
- Old data refreshes on schedule or engagement
- Reps always work with current information
- No “cleanup sprints” needed
The difference isn’t just data quality. It’s operational consistency.
When enrichment is continuous, your CRM becomes reliable. Routing works. Sequences don’t break. Reps don’t waste time on disconnected numbers.
Start here
Your CRM data is decaying right now. The question isn’t whether to fix it—it’s whether you want to be a data janitor once a year or a sales leader with a self-maintaining system.
By combining Lusha’s batch and real-time enrichment, your CRM stops being a cleanup project and starts being the high-performance infrastructure your team deserves.
