What is data decay?

Even a perfectly clean database rots on its own. Nobody enters bad data on purpose - the world just changes underneath the records.

Because decay is constant, the fix is not a one-time cleanup but ongoing enrichment and verification that refresh records as reality shifts.

Short answer

Data decay is the gradual loss of accuracy in CRM records as the real world changes. People switch jobs, companies rebrand or move, and emails stop working. B2B contact data decays roughly 25 to 30 percent per year, which is why a database left alone slowly becomes unreliable.

Key takeaways

  • Records lose accuracy over time as jobs, companies, and contact details change.
  • B2B contact data decays around 25 to 30 percent per year.
  • Decay happens even to data that was perfectly clean when entered.
  • The remedy is continuous re-verification and enrichment, not a single cleanup.

Why it matters

Decay silently erodes everything: outreach bounces, reps call disconnected numbers, and routing sends leads to people who left. A database that was accurate a year ago can be a quarter wrong today if nothing refreshes it.

How Ardovo handles it

Ardovo continuously re-verifies and enriches records, so Rook flags when a contact likely changed jobs or an email stopped resolving. Decay gets caught and corrected as it happens instead of discovered when a campaign bounces.

Frequently asked questions

How fast does CRM data decay?

B2B contact data typically decays 25 to 30 percent per year as people change jobs and companies change details. That means a meaningful share of your database is wrong within a year unless something actively refreshes it.

How do you fight data decay?

Continuously re-verify and enrich records rather than cleaning once. Track email deliverability and job-change signals, refresh firmographic data on a schedule, and flag records that have not been touched or confirmed in a long time.

What causes data decay?

Real-world change: people switch roles or companies, businesses rebrand, relocate, or shut down, and phone numbers and emails get retired. None of it is a data-entry mistake - the record was right when created and reality moved.
