Smart Network Data Services (SNDS)

Smart Network Data Services (SNDS), by Microsoft Outlook, is a free tool that provides insights into how Microsoft Outlook views the health of a brand’s IP address. SNDS also provides information about a brand’s bounce percentage, spam trap hits, and the number of emails sent from the brand’s IP address – all of which help the brand assess its sender reputation and email deliverability. Good sender reputation enables inbox service providers (ISPs) to validate the brand’s domain name and place emails in recipients’ inboxes without speculation.
