    Between 03:53 PM UTC to 4:08 PM UTC we saw email send failures elevate in which a small number of customers (10 enterprise, 8 self-serve, and 1 pro plan) were impacted. This came to 508 emails in total, or ~1% of our daily email send. We are working to ensure this failure mode is not able to happen again.
