Site Health Email Aggregation Change in WordPress 6.5

Site Health Email Aggregation Change in WordPress 6.5

Goal: reduce notification noise from Site Health emails while ensuring administrators still receive timely alerts for critical issues.

Constraint: WordPress 6.5+ sends a separate email for each Site Health test that returns a recommended or critical status, and there is no built‑in UI to suppress low‑priority tests or to combine multiple results into a single digest.

Uncertainty: the core ticket #56023 leaves open whether Site Health should aggregate test results into a digest email or keep individual alerts, forcing site owners to choose between completeness and noise.

• What criteria should determine which tests are aggregated into a digest email?
• How would a digest email affect the timeliness of receiving critical alerts?
• Should administrators be able to opt‑in to digest mode through a settings screen, and if so, what default behavior would preserve backward compatibility?
