How to Evaluate Business Contact Data Freshness

Why it matters: Import time records when a system received data. Observation time records when a source saw it. Verification time records when a specific check ran. These dates answer different questions. An email syntax check performed this morning does not confirm employment or mailbox existence, and an updated company page does not validate every listed employee.

• Keep import and observation dates distinct.
• Record which field a check actually covered.
• Do not label an entire record fresh after one narrow check.

Why it matters: Before a high-value campaign, recheck current role, company association and the intended contact channel. Review records with recent job changes or weak provenance first. A uniform recheck interval is simple, but different fields change at different rates. Use uncertainty and business value to decide where manual research is worthwhile.

• Confirm senior contacts before highly personalized outreach.
• Treat unexplained source conflicts as review candidates.
• Keep previous values for traceability when appropriate.

Why it matters: A hard bounce, wrong-person reply or job-change response is evidence about data quality. Suppress invalid addresses and correct the relevant association rather than simply retrying. Track failure rates by source and age band. That reveals whether a particular dataset is becoming stale and prevents the same mistake from being repeated in future exports.

• Keep delivery failures separate from engagement outcomes.
• Recheck before reusing an old campaign list.
• Never interpret silence as confirmation that data is current.
