## Updates from SparkPost
### 2026-04-05 17:02 UTC: investigating
We are currently investigating reports of delayed or failed email deliveries to Apple-hosted domains. Messages to non-Apple domains are unaffected. We will provide updates as more information becomes available.

### 2026-04-05 17:58 UTC: identified
The issue was caused by an Apple iCloud Mail outage (https://www.apple.com/support/systemstatus/), which Apple has since marked as resolved. Bounce rates and delivery delays to Apple domains have returned to normal levels. We are currently reviewing our suppression lists to identify and remove any recipients that may have been incorrectly added during the incident.

### 2026-04-05 18:27 UTC: monitoring
Apple has implemented a fix and we are monitoring the results.

### 2026-04-05 19:01 UTC: resolved
Delivery rates to Apple domains have returned to normal with no further elevated delays or bounces. We will perform any necessary post-incident cleanup of suppression lists to ensure no recipients were incorrectly suppressed during the outage.
NOTE: As of Monday April 5th at 9PM EDT the cleanup has been completed. All recipient addresses to Apple or Apple Private Relay domains that were suppressed during Apple's incident window were removed.
