Email Revalidation Policy: 30 vs 60 Days
A revalidation policy defines how often email statuses are re-checked. The right window is a balance between freshness, stability, and operational cost — and it can vary by provider behavior.
Short windows (≈30 days)
- Fresher signals for fast-changing mailboxes
- More frequent checks can surface transient outcomes
- Higher recheck load (platform cost / rate limits)
Conservative windows (≈60 days)
- More stable export experience
- Lower recheck frequency and fewer bursts
- May lag behind changes for certain addresses
Side-by-side comparison
| Dimension | ~30 days | ~60 days |
|---|---|---|
| Freshness | Higher | Moderate |
| Stability | Can be noisier on some providers | Often more stable |
| Operational load | Higher | Lower |
| Best for | Rapidly changing segments | Predictable exports and steady cadence |
