Email Guard is your reputation sentinel. It continuously monitors your email sending patterns, domain health, and inbox placement rates. In a landscape where a single mistake can damage your sending reputation for months, Email Guard provides the monitoring and protection necessary for professional-grade operations. Especially after Outlook made it harder to send cold emails to Outlook accounts, Email Guard has become our savior by providing the inbox placement test feature. It shows you if any of your inboxes cannot land Outlook accounts, and you can use a different account instead.
