  1. monitoring Feb 26, 2026, 05:49 PM UTC

    We are currently seeing elevated delivery delays to Microsoft-hosted email addresses (including Outlook, Hotmail, Live, and MSN). Microsoft has acknowledged an issue that is causing certain sending IP addresses across the industry to be temporarily rejected at higher-than-normal rates. This is not related to invalid email addresses or a system outage on our platform. Emails are being temporarily deferred by Microsoft's servers and retried automatically. We are actively monitoring the situation, working with our email delivery provider, and adjusting sending patterns where necessary to help restore normal delivery as quickly as possible. We will continue to provide updates as Microsoft resolves the issue.

  2. resolved Feb 27, 2026, 04:15 PM UTC

    Our monitoring indicates that 100% of the emails were delivered yesterday. We will still be monitoring this behind the scenes.
