Summary
After adding an IP address to Microsoft SNDS Live and gaining approval, the common expectation is for data to begin appearing fairly quickly. Most insights suggest that if the necessary volume criteria are met, you should start seeing data the very next day. However, it is important to note that SNDS does not typically backfill historical data, meaning you will only see data from the point your IP is approved and begins sending sufficient volume. While generally consistent, occasional lags in data reporting can occur, leading to slight delays in updates.
Key findings
- Data appearance: If an IP is approved and meets volume criteria, data typically appears in SNDS Live the next day.
- No backfill: Microsoft SNDS does not backfill data; you will only see information from the time your IP is active and sending.
- Update frequency: Data updates in SNDS are generally daily, but may experience occasional delays or inconsistent schedules.
- Criteria for data: Data visibility hinges on both IP approval and meeting Microsoft's sending volume requirements to generate sufficient activity for reporting.
Key considerations
- Monitoring new IPs: Be prepared to monitor your IP's sending activity immediately after approval to ensure it meets the volume thresholds for SNDS data generation. Understanding why new IPs might remain red in SNDS during warming can be crucial.
- Volume is key: Without sufficient sending volume to Microsoft mailboxes (like Outlook), SNDS will not have enough data to report on, even if the IP is approved. This is often tied to email sender reputation.
- Anticipate delays: While next-day reporting is common, always account for the possibility of minor delays. If data is not appearing as expected, consider troubleshooting SNDS data accessibility.
What email marketers say
Email marketers often look to Microsoft SNDS for insights into their IP reputation and deliverability to Outlook.com and other Microsoft consumer mailboxes. Their experiences with data appearing in SNDS Live after IP approval generally align with official guidelines, suggesting a relatively quick turnaround if sending volume criteria are met. However, marketers also acknowledge that deliverability metrics can sometimes be inconsistent, even with SNDS showing a normal status, highlighting the complexities of Microsoft's filtering systems.
Key opinions
- Quick reporting: Many marketers expect to see data within a day of IP approval, provided adequate email volume is being sent.
- Volume necessity: There's a strong consensus that sufficient sending volume is a prerequisite for any data to populate in SNDS.
- Potential for lag: While often timely, some marketers report occasional lags or inconsistencies in SNDS data updates, similar to other postmaster tools.
Key considerations
- Understanding volume: Marketers need a clear understanding of what constitutes sufficient IP volume for SNDS to ensure data begins flowing.
- Patience is key: Despite the general expectation of next-day data, marketers should maintain patience and monitor for a few days, especially during IP warming.
- Beyond SNDS: Marketers recognize that SNDS provides one piece of the puzzle, and other factors, such as overall Microsoft deliverability inconsistencies, can influence inbox placement.
Marketer view
An email marketer from Spiceworks Community shares their frustration when an expected quick resolution to a Microsoft blacklisting issue turned into over 72 hours of waiting without data. They usually see issues resolved within a few hours, indicating this extended delay was unusual and concerning for operations.
Marketer view
A marketer from Email Geeks observes that if access to SNDS is approved and the sending volume criteria are met, data should start appearing the very next day. They also noted that Microsoft's SNDS doesn't seem to backfill any historical data for the newly added IPs.
What the experts say
Experts in email deliverability emphasize that Microsoft SNDS is designed to provide near real-time insights into IP reputation, with data typically appearing the day after an IP is approved and begins sending sufficient volume. They caution, however, that while the system aims for regularity, occasional operational lags can occur. The critical factor for data visibility is consistently meeting Microsoft's thresholds for sending activity, as SNDS focuses on providing high-level insight into an IP's current sending behavior rather than backfilling historical trends.
Key opinions
- Daily reporting: Experts generally agree that SNDS data should be visible the day after IP approval, provided adequate email volume is sent.
- Volume dependent: The appearance of data is contingent on the IP meeting Microsoft's volume criteria, indicating that minimal sending will result in no data.
- No historical data: It's widely understood that SNDS does not backfill data, meaning only new activity from the approval date will be reported.
- Occasional delays: While generally reliable, experts acknowledge that there can be occasional lags or inconsistencies in data updates.
Key considerations
- Consistent sending: To ensure continuous data flow, maintain consistent and sufficient email sending volumes to Microsoft recipients after IP registration. Consistent sending aids in improving domain reputation.
- Volume criteria: Be aware of Microsoft's minimum sending volume requirements for SNDS data to appear. For new IPs, this is a crucial aspect of IP warming.
- Expect minor fluctuations: While daily updates are standard, plan for minor variations in the timing of data refreshes within SNDS. If data seems contradictory during warming, investigate potential reasons for inconsistencies.
Expert view
An expert from Email Geeks states that if access to SNDS is approved and the required sending volume criteria are met, senders should expect to see data reported as early as the next day. They also confirm that historical data is not backfilled by SNDS.
Expert view
An expert from Spam Resource notes that SNDS provides high-level insight into an IP's email deliverability and sender behavior, specifically for Microsoft consumer mailboxes like Outlook. This underscores the primary purpose of SNDS data once it becomes available.
What the documentation says
Microsoft's official documentation and authoritative resources on SNDS consistently state that the service provides near real-time data on the reputation of IP addresses sending to Microsoft consumer mailboxes. Data is processed daily, and once an IP is successfully registered and begins sending qualifying email volume, information typically appears within 24 hours. The primary purpose of SNDS is to give senders insight into their current standing, allowing them to proactively manage their sending reputation and identify potential issues like blocks or poor filtering results.
Key findings
- Daily updates: SNDS data is updated daily, providing a current snapshot of an IP's reputation.
- Next-day visibility: Data generally becomes visible the day after an IP is registered and begins sending qualifying traffic.
- Volume is critical: A certain threshold of email volume must be sent to Microsoft recipients for data to be generated and displayed in SNDS.
- Reputation insight: SNDS offers high-level insights into how Microsoft's filters perceive an IP, including whether mail is being treated as spam.
Key considerations
- Account setup: Ensure your SNDS account is properly set up and IP addresses are correctly added to avoid delays in data visibility. For instructions on how to add users to SNDS, refer to the relevant guides.
- Monitoring spam rates: Utilize the spam rate data within SNDS to proactively identify and address deliverability issues. This data is crucial for preventing IP blocklisting.
- Consistency of sending: Maintain consistent sending patterns to ensure continuous and reliable data flow in SNDS, which aids in stable IP reputation.
