We've made changes to address the intermittent delivery delays. Since then, email has been delivered without delay, including during peak sending periods that previously caused the slowdowns. We're watching closely to confirm the issue is fully resolved and will post an update here. Thank you for your patience.

Investigating
Some email deliveries are being delayed. The delays come and go, and queued messages are being delivered once each one clears. Our team is investigating the cause and working on a fix. We'll post an update here as soon as we know more. We apologize for the disruption.
