ESPs deny direct SNDS access due to a confluence of factors revolving around control, security, potential misuse, and overall deliverability management. Key reasons include the ESP's ownership of the IPs, the inability to revoke access once granted, the risk of customers misinterpreting complex SNDS data leading to harmful actions, the potential exposure of other senders' data due to security vulnerabilities, and the desire to manage the narrative around deliverability. Furthermore, ESPs aim to protect their shared IP pool reputation and shield themselves from legal liabilities arising from customer misuse or violations of terms. Alternatives like Google Postmaster Tools are sometimes promoted for a more holistic view, and aggregated, user-friendly data presentations are preferred to raw SNDS data.
