What’s the difference between “temporary dip” and “systemic degradation”?

Temporary dip: Short-term fluctuation that self-resolves.

Lasts hours to a few days

Often caused by provider algorithm changes, temporary blocklisting, or volume fluctuations

Recovers without major intervention

Does not worsen over time

Systemic degradation: Persistent decline requiring intervention.

Lasts weeks or longer

Caused by fundamental problems (list quality, authentication, reputation damage)

Requires active remediation

Often worsens if ignored

How to tell the difference:

Monitor for 2-3 days before panicking

If metrics continue declining, it is systemic

If metrics stabilize or improve, likely temporary

Check for clear causes (blocklist, spike) versus gradual drift
