## Updates from beehiiv
### 2026-08-21 14:31 UTC: identified
We have identified an issue with an upstream email provider resulting in some posts not being delivered to the full intended subscriber list. It is effecting ~20% of large publications with an average impact of a 4-8% non delivered rate. We are working with the vendor to resolve the issue and will deliver all posts to impacted subscribers.

### 2026-08-21 16:20 UTC: identified
We are continuing to work with the vendor for a comprehensive fix to the issue but have implemented a workaround and are delivering the dropped emails for all effected newsletter sends

### 2026-08-21 18:15 UTC: monitoring
Our email sending provider identified the root cause as a bad deploy on their end, which they reverted ~40 minutes ago. All posts are sending successfully, we will continue to monitor closely over the rest of the day.

### 2026-08-21 18:44 UTC: resolved
This incident has been resolved.
