Increased Microsoft Inbox Provider Blocks

Resolved - Our Engineering team has completed monitoring and confirmed that no SendGrid-specific issues remain at this time. Microsoft has acknowledged that some senders may continue to experience elevated throttling, and has confirmed that this behavior is not isolated to SendGrid nor specific to our sending configuration.

Microsoft has advised that any additional updates will be communicated via their Smart Network Data Service (SNDS) page. Customers who continue to experience deferrals or blocks when sending to Microsoft Outlook Consumer domains (for example, hotmail.com or outlook.com) are encouraged to open a support request directly with Microsoft for further assistance:

All SendGrid services are operating normally, and we will continue to monitor for any relevant upstream updates.

Update - We have acknowledgment from Microsoft about the change in delivery behavior on their consumer email platform. Microsoft has acknowledged that the behavior is not isolated to SendGrid's environment and is not specific to our sending configuration.

Our engineering team is seeing improvement (reduction) of deferrals since the start of the incident on 1/14. Blocks have also reduced but are still at elevated levels; we will keep monitoring the behavior.

Customers that feel they are continuing to observe excessive deferrals and/or blocks should fill out the OLC Support request form at https://olcsupport.office.com/

Jan 24, 08:58 PST

Investigating - Starting around 1:00 PM UTC on January 24, 2026, our engineers began investigating an issue with email delivery to Gmail recipients.

Users may experience delivery delays, with emails taking up to 5x longer than usual to reach Gmail addresses. This is due to an issue on the Gmail/Google side, as other email providers remain unaffected.

This does not impact mail send; Emails are successfully delivered to Gmail's mail servers; however, Gmail is experiencing delays in delivering those messages to recipient inboxes. You can monitor the status of Google services via the official Google Status Page: https://www.google.com/appsstatus/dashboard/

We will provide another update as soon as more information becomes available.
