Blacklist protection

Sending out spam through your company’s email server is terrible for business. However, when one or more of your employees are compromised, it’s possible to get blacklisted. Many other servers will block any emails from your account and prevent others from reaching their inboxes. Incoming spam protection helps you to keep your IP address clean and notified of any issues so you can fix them as soon as possible.

Protect your brand and reputation

Your brand’s reputation is on the line when your organization sends out spam or viruses. MailBuster ensures that only correctly vetted emails are sent from your server and stops the spread of malicious content, protecting your company and its customers.
