We're aware of an issue currently affecting email delivery to Microsoft domains (Outlook, Hotmail, Live). This is a receiver-side issue on Microsoft's end and is being seen industry-wide, with multiple email providers reporting the same behaviour this morning. It is not an indication of a problem with your account, your sending, or our platform. We've raised this directly with Microsoft and are awaiting their response. Mail to other providers is unaffected. We'll share an update as soon as we hear back. Thanks for your patience.

We are continuing to monitor delivery of emails to Microsoft domains. Whilst we have seen some improvement and many emails are getting through, there is unfortunately continues to be a proportion of emails not being delivered successfully.

We'll share an update as soon as we have more information.

Delivery to Microsoft domains (Outlook, Hotmail, Live) has improved since last Friday. Some sending IPs are still seeing delays, so you may notice slower delivery to Microsoft addresses on some campaigns while this resolves or elevated soft bounces.

This remains a receiver-side issue on Microsoft's end and is not related to your account, your sending, or our platform. We've been in contact with Microsoft and are continuing to monitor closely as delivery recovers.

Thanks for your continued patience.

[in progress]

Delivery to Microsoft domains has improved significantly, though we're still seeing fluctuations in successful delivery rates. We're continuing to monitor closely and make adjustments to mitigate the impact where we can.

This remains a receiver-side issue on Microsoft's end and is not related to your account, your sending, or our platform. We've been in contact with Microsoft and are continuing to monitor closely as delivery recovers.

In the meantime, we recommend holding off on resending campaigns to Microsoft-domain subscribers that have bounced until the issue is fully resolved.
