Why I can't see any data in my Microsoft SNDS

Arshiya Shaikh 0

I've authorized my sending IP in Microsoft SNDS and I've been sending emails from that same IPs for the past 10 days (about 50k emails total), but I still see no data in SNDS. The emails are definitely going out through the authorized IP. Why is there no data showing up?

Hi @Arshiya Shaikh,

Based on what you've described, one possible explanation is that SNDS (Smart Network Data Services) only reports traffic delivered to Microsoft's consumer email services, such as Outlook.com, Hotmail.com, Live.com, and MSN.com.

If most or all of the approximately 50,000 emails you've sent over the last 10 days were delivered to Microsoft 365 business domains, it would be expected for the SNDS "View Data" page to remain empty.

It's also worth noting that SNDS data is not updated in real time. Microsoft processes and publishes SNDS statistics once per day on a Pacific Time schedule, so activity from the previous day may not appear until after the next aggregation cycle has completed.

To verify that everything is working correctly, you could try the following:

Send a test message through your Marketing Cloud route to a real Outlook.com or Hotmail.com mailbox.
After the message is delivered, open the message headers/source and confirm that the IP address shown in the "Received from" line matches the IP address you registered in SNDS.
Wait until the next daily SNDS update cycle and then check View Data again.
If the message headers show a different outbound (egress) IP than the one currently registered in SNDS, add the actual sending IP shown in the headers to SNDS and use that IP for future monitoring.

Could you also confirm whether your recent mailings were primarily sent to Outlook.com/Hotmail recipients, or were they mostly sent to Microsoft 365 business tenants?

Thank you for your patience and understanding. I hope this information will be useful to you.

I've authorized my sending IP in Microsoft SNDS and I've been sending emails from that exact IPs for the past 10 days (around 50k emails total), but I still see no data in SNDS.

I verified with a test message sent to a real consumer Outlook.com mailbox. The message headers confirm:

SPF passes and designates my sending IP as the permitted sender

DKIM passes

DMARC passes

The X-Sender-IP in the headers matches the IP I authorized in SNDS

So the IP is correct, authorized, and the recipient is a consumer Outlook.com mailbox. Yet SNDS shows nothing. The message was also tagged with X-MS-Exchange-Organization-SCL: 5 and delivered to Junk.

Why would SNDS still show no data when the IP is authorized, the mail is being sent from that IP, and it's reaching a consumer Outlook.com mailbox?

Hi @Arshiya Shaikh,

Thank you for the additional details. Since you've confirmed that:

The sending IP matches the IP authorized in SNDS

SPF, DKIM, and DMARC are all passing

The message is reaching a consumer Outlook.com mailbox

The headers show the expected sending IP

further investigation would likely require access to Microsoft's backend SNDS data and telemetry.

As a forum user, I do not have access to Microsoft's internal systems, reputation data, or SNDS processing records, so I am unable to determine why your IP is not appearing in the SNDS reports despite the checks you've already performed.

At this point, I would recommend contacting Hotmail Sender Support and submitting a support request using the following form:

Hotmail Sender Support Form

You may also find the SNDS FAQ helpful, as it contains additional information about SNDS reporting behavior, data availability, and common troubleshooting scenarios.

When contacting Hotmail Sender Support, it would be helpful to include:

The authorized SNDS IP address

Sample message headers showing the sending IP

Confirmation that the message was delivered to an Outlook.com mailbox

The approximate date and time of the test message

A screenshot of the SNDS "View Data" page showing no results

I apologize that I cannot investigate this further from the forum side, but the Hotmail Sender Support team is best positioned to review the backend data and determine why SNDS reporting is not appearing for your IP.

Thank you for your understanding, and I hope this points you to the appropriate support channel.
