We tested 10,000 contacts from leading providers and found something shocking.
The Experiment
We purchased 10,000 "verified" business contacts from ZoomInfo, Apollo.io, and a third major provider. All contacts were flagged as "verified within the last 30 days."
After 30 days, we re-verified every single contact. Here's what we found:
The Data Decay Reality
| Issue Type | Percentage | Impact |
|---|---|---|
| Email bounced | 23% | Immediate delivery failure |
| Person changed jobs | 18% | Wrong company entirely |
| Title changed | 15% | Wrong decision maker |
| Company no longer exists | 7% | Total dead end |
| Phone disconnected | 4% | Can't make contact |
| Total Issues | 67% | 2 out of 3 had problems |
Why 7-Day Freshness Changes Everything
The math is simple but brutal:
- 30-day refresh: 67% accuracy issues after one cycle
- 7-day refresh: Reduces issues to under 15%
Real-World Impact:
If your team sends 10,000 emails per month:
- 30-day data = 6,700 wasted sends
- 7-day data = 1,500 wasted sends
- Net gain: 5,200 more real conversations per month
The Hidden Costs You're Not Tracking
1. Deliverability Damage
High bounce rates hurt your email sender reputation. Your domain gets flagged, and even your good emails start landing in spam.
2. Sales Rep Morale
Nothing kills SDR motivation faster than constant bounces and "this person doesn't work here anymore" responses.
3. Opportunity Cost
While your reps chase ghosts, your competitors with fresh data are booking meetings with real buyers.
