How to Submit an Outlook / Hotmail Email Delisting Request
If your emails are being blocked or marked as spam by Microsoft Outlook (Outlook.com / Hotmail / Live), you can request removal by submitting a delisting request directly to Microsoft.
Important Prerequisite: Verify DNS Records Before Submitting Delist Request
Before submitting a delisting request to Microsoft Outlook, it is mandatory to ensure that all required email authentication records are properly updated and publicly visible.
Microsoft may reject or ignore delist requests if DNS records are missing or incorrectly configured.
Go to:
https://dnschecker.org
Verify SPF Record
Select TXT record type
Enter your domain name (example: example.com)
Verify DKIM Record
Select TXT record type
Enter DKIM selector with domain
Example:
selector1._domainkey.example.com
Verify DMARC Record
Select TXT record type
Enter:
_dmarc.example.com
Confirm Global Propagation
Ensure records are visible from multiple locations
If some locations show ❌, wait up to 24 hours for DNS propagation
Only After Successful DNS Verification
Once SPF, DKIM, and DMARC are confirmed as correctly published and propagated, proceed to submit the Outlook Delisting Request.
