IP address reputation is measured based on several factors, including:
Spam Complaints: High rates of spam complaints from recipients can damage your IP reputation. Bounce Rates: A high number of bounced emails indicates poor list management and can negatively impact your score. Email Volume: Sending a large volume of emails in a short time can raise red flags, especially if the IP address is new. Engagement Metrics: Positive engagement, such as opens and clicks, can improve reputation, while low engagement can hurt it. Blacklist Status: Being listed on any blacklists will significantly damage your IP reputation.
