Your Contact Database Is Rotting 2% Every Month
B2B contact data decays at roughly 2.1% per month. In the tech sector, annual churn on contact records reaches around 40% — people change jobs, companies switch tools, titles get reshuffled. That means the “fresh” list you bought in January is measurably degraded by June, and nearly half-wrong by the following year. This isn’t a vendor problem you can name and shame — it’s physics. The real problem is what the industry does about it: mostly nothing, and mostly silently.
The Silent Part: Nobody Tells You When a Record Was Last Checked
Here’s the detail that should bother you more than the decay rate itself: major data providers generally don’t publish last-verified timestamps on their records. Refresh cycles are opaque — analysis suggests some records go six months or more without re-verification, especially for smaller accounts. So freshness degrades invisibly. You find out a record is stale the moment it bounces, or when a confused stranger answers the phone.

What Decay Actually Costs You
- Bounces that damage sender reputation — compounding across every future campaign
- SDR hours spent on dead records — the most expensive way to discover staleness
- Displacement pitches referencing tools no longer in use — credibility damage you can’t A/B test away
Quick self-audit: ask your current data provider one question — “When was this record last verified?” If they can’t answer per-record, you’re buying decay on a delay.
Revnity’s answer to decay is verification at delivery plus contractual accountability: 100% technology accuracy, 98% deliverability, and free replacement of any inaccurate record. Decay still happens — but you’re never the one absorbing its cost. Read [why most technographic data is wrong] for how verification actually works, or see our Technographic Data page.
