## Updates from Telnyx
### 2026-10-12 08:31 UTC: investigating
We are currently investigating this issue.

### 2026-10-12 09:36 UTC: monitoring
Email sending through the Telnyx Email API was unavailable during the following periods:
• 9th October, approximately 21:10–22:05 UTC.
• 10th October at approximately 22:15 UTC until 12th October at 09:25 UTC.
New send requests during these periods failed with \*\*\_gw\_reject// injection\_failed\_\*\*. Messages already queued before each interruption continued to be sent. Customers can retry messages that failed during the affected periods.
Service has been restored following a mitigation. We are monitoring stability and working on a permanent fix.
