  1. Investigating

    Starting around 9:25 AM GMT+8 on June 10, 2026, our engineers began investigating an issue affecting email processing within SendGrid. Users may have experienced elevated email deferrals, with some messages temporarily receiving "Internal Server Error" responses during delivery attempts. This issue does not impact mail send capability; however, delivery may have been delayed for a subset of messages. Our team continues to investigate the root cause and monitor system performance. We will provide another update in 60 minutes or as soon as more information becomes available.

  2. Monitoring

    Our engineers have implemented a fix and are monitoring system performance. We will provide another update in an hour or as soon as more information becomes available.

  3. Resolved

    Our engineers have monitored the fix and confirmed the issue with email deferrals has been resolved. All services are now operating normally at this time.
