SNDS offers a range of metrics that are crucial for monitoring your email sending practices:
Complaint Rate: This indicates the percentage of users marking your emails as spam. A high complaint rate can damage your sender reputation. Spam Trap Hits: These are email addresses used to catch spammers. Hitting a spam trap suggests you're not maintaining a clean email list. IP Reputation: This tells you how Microsoft views your sending IP. A poor reputation can lead to your emails being filtered as spam.
