What Is Microsoft Smart Network Data Services (SNDS) and Do I Need It?

Microsoft Smart Network Data Services (SNDS) offers email senders valuable insights into their email activity, aiming to enhance deliverability by providing data from Hotmail and Microsoft mail server logs. SNDS tracks email activity per IP address, detailing metrics like RCPT commands (emails sent), DATA commands (emails accepted), and message recipients (emails delivered), along with spam filter results, complaint reports, and spam trap hits. The service helps in monitoring IP reputation, identifying potential deliverability issues such as high bounce rates or spam complaints, and resolving these with targeted strategies. Access to SNDS data is facilitated through Twilio SendGrid, allowing users to request and monitor data to make informed decisions about email deliverability.
