Data Decay Is Costing You Placements (And You Cannot See It Happening)
Every month, a slice of your database quietly goes wrong: candidates change jobs, direct dials stop working, emails start bouncing. You do not notice until a search returns people who moved on two years ago. This post covers why recruitment data decays faster than most agencies realise, what it costs in placements, and how to keep records live without endless manual clean-up.
Your database is the single most valuable asset your agency owns. Years of sourcing, conversations, and placements are captured in it. And it is degrading right now, while you read this, without any visible sign that it is happening.
This is data decay — the slow, silent process by which accurate records become wrong. It is one of the few problems in recruitment that costs you money every single day while remaining almost completely invisible until the moment it bites.
How fast recruitment data actually decays
The numbers are worse than most people assume. People change jobs, get promoted, switch companies, change their mobile number, abandon an old email address. Every one of those events turns a correct record into a wrong one. Industry estimates commonly put B2B contact data decay at roughly 30% per year — and recruitment data, tied to people whose entire value is that they move roles, decays at least as fast.
A candidate database is not a filing cabinet. It is a living thing that gets a little bit wrong every day you do not touch it.
What decay actually costs you
- Missed placements. The perfect candidate is in your database — but the record shows a dead number and a bounced email, so your search skips them or your outreach never lands.
- Wasted consultant time. Recruiters burn hours chasing contacts that no longer exist, re-finding people you already had.
- Damaged deliverability. Sending to dead and bouncing addresses wrecks your sender reputation, so even your *good* emails stop reaching inboxes.
- Compliance drift. Stale records are also the records most likely to be sitting past their retention period — a GDPR exposure as much as a commercial one.
Why manual clean-up never works
Every agency knows they *should* clean the database. Almost none do it consistently, because manual data hygiene is the definition of a task that is always less urgent than the placement in front of you. "Database clean-up week" gets scheduled, deprioritised, and forgotten — and the decay compounds in the meantime.
The only approach that works is one where the system keeps records fresh as a by-product of normal work, rather than depending on someone remembering to do a chore.
What a living database looks like
- Every email interaction updates the record — bounces flag bad addresses automatically instead of silently failing.
- New information captured during normal conversations (a new role, an updated number, a salary expectation) is written back to the profile, not lost in a call you half-remember.
- Duplicate detection runs continuously, so the same candidate does not fracture into three half-complete records.
- Search understands recency, so the people you have engaged recently surface ahead of ghosts from five years ago.
Start with the records you actually use
You do not need to boil the ocean. The candidates and clients you contact regularly are the ones where decay hurts most and where fixing it pays back fastest. A CRM that keeps *those* records live as you work is worth more than an annual purge that is already out of date by the time it finishes.
