We are currently experiencing email deliverability issues affecting recipients using Microsoft-managed email domains, including: hotmail.com outlook.com msn.com live.com Some emails sent to these domains may be delayed or blocked due to IP reputation filtering by Microsoft’s mail servers. We are actively working with our email infrastructure provider and Microsoft’s postmaster tools to resolve the issue. No action is needed on your end at this time, and we will provide updates as soon as we have more information.
