Gaining direct access to Microsoft Smart Network Data Services (SNDS) when using an Email Service Provider (ESP) is generally not possible for individual customers, especially those on shared IP addresses. This is because SNDS access is fundamentally linked to the ownership and management of IP addresses, which reside with the ESP. ESPs proactively manage their IP pools within SNDS, handling registration, monitoring, and reputation maintenance to ensure optimal deliverability for all their users. Therefore, end-users typically rely on their ESP's deliverability team for SNDS-related insights and reputation management, as the data belongs to the IP owner. However, for clients utilizing a dedicated IP address from their ESP, direct SNDS access might be achievable, but it necessitates direct coordination and approval from the ESP to verify control over that specific IP. If direct access is not an option, customers should inquire if their ESP can provide relevant reports or data insights derived from their SNDS monitoring.

For marketers leveraging an Email Service Provider (ESP) for their email campaigns, obtaining direct access to Microsoft's Smart Network Data Services (SNDS) is typically not an option, particularly when utilizing shared IP addresses. This limitation stems from the fact that SNDS access is inherently tied to the ownership and active management of sending IP addresses, a responsibility that lies firmly with the ESP. These providers proactively oversee their IP pools within SNDS, handling all aspects of registration, ongoing monitoring, and reputation maintenance to ensure optimal deliverability for their entire client base. Consequently, individual users generally rely on their ESP's dedicated deliverability teams for any SNDS-related insights or reputation management data. While direct access is largely unavailable for shared IP users, clients on dedicated IP addresses might have a pathway to obtaining SNDS access, though this always requires specific coordination and approval from their ESP to verify control over the allocated IP. If direct access is unfeasible, customers should inquire about receiving relevant reports or data insights that their ESP can generate from their own SNDS monitoring.
Marketer view
Marketer from Email Geeks explains that the SNDS authorization email addresses are related to the IP's PTR (reverse-DNS) record. He clarifies that if you use an ESP, you typically cannot gain direct SNDS access this way and should request it from your ESP, as it depends on who manages the IP space.

Marketer from Email Geeks shares a four-step algorithm for gaining SNDS access through an ESP: talk to your ESP, submit the form, ESP confirms, then access. He also clarifies that SNDS access can be revoked by initiating a "request reauthorization" in the Access Control section, or it expires automatically after 7 days if the link isn't clicked.

Access to Microsoft Smart Network Data Services (SNDS) when using an Email Service Provider (ESP) is primarily managed by the ESP themselves, as SNDS data is inherently linked to the IP addresses they control. For users on shared IP addresses, direct SNDS access is typically unavailable, but the ESP may offer reports or insights derived from their data. Conversely, clients utilizing dedicated IPs with their ESP might have a possibility of gaining direct SNDS access or receiving specific data for those IPs. The most effective step for any user is to directly consult their ESP regarding their policies and capabilities concerning SNDS data.
Expert view
Expert from Spam Resource explains that Microsoft SNDS access is typically controlled by the Email Service Provider (ESP) because SNDS data is tied to IP addresses. If you are using shared IPs, your ESP will manage this data and will likely not grant direct access, but might provide reports or insights based on the data. If you have dedicated IPs with your ESP, it may be possible for them to grant you direct SNDS access or provide you with the relevant data for those IPs. The best approach is to contact your ESP directly to inquire about their policy and capabilities regarding SNDS data.

When an organization leverages an Email Service Provider (ESP) for email campaigns, direct access to Microsoft's Smart Network Data Services (SNDS) for their sending IPs is typically not granted to the end-user. This is because SNDS access is inherently tied to the ownership and active management of IP addresses, which remains with the ESP. For customers utilizing shared IP pools, the ESP's deliverability team takes full responsibility for registering, monitoring, and maintaining the reputation of these IPs within SNDS, ensuring optimal deliverability across their client base. While this centralized management benefits all users, it means individual customers on shared IPs usually cannot view raw SNDS data. However, for clients operating with a dedicated IP address through their ESP, there may be a pathway to secure direct SNDS access, although this requires explicit coordination and approval from the ESP to verify control over that specific IP. Ultimately, end-users should consult their ESP regarding their policies on SNDS data access or for any relevant reports.
Technical article
Documentation from Microsoft Learn explains that users of Email Service Providers (ESPs) who send email from shared IP addresses do not typically need to register for SNDS directly. Instead, the ESP is responsible for managing their IPs in SNDS. End users will not be granted access to the shared IPs in SNDS, as the data belongs to the IP owner, which is the ESP. Access for specific IPs is granted only to the IP owner.

Documentation from Microsoft Postmaster Tools clarifies that the Smart Network Data Services (SNDS) program is primarily designed for Mailbox Providers and Internet Service Providers (ISPs) that own the IP addresses used for sending email. If you are an end-user of an Email Service Provider, the ESP itself is responsible for registering and managing their IP addresses within the SNDS program. Direct access for individual ESP customers to their ESP's shared IPs in SNDS is not provided.
