Reputation in the email world typically refers to the email service provider (that’d be us). Reputation is how well the service is received by email clients (GMail, Yahoo, Outlook, etc.) and indicates the trustworthiness of the IP address from which the email is sent. Unlike a high school reputation, the IP reputation is actually based on reality. The number is dragged down by spam complaints. At MNB, we protect your reputation by preventing people from sending spam on our service and suspending accounts with too many complaints.
