It's easy to use, it protects against spam as well (it also blocks phishing links). I have seen some issues with false positives but this can be improved over time by using more sophisticated filters in conjunction with other tools such as SpamAssassin or similar products from third party vendors like Zixia/Zemana etc., which are capable at detecting advanced spammers' techniques better than any product out there today! Highly recommended if you want protection without sacrificing your inbox performance too much - we've saved almost 80% mailboxes space compared to our "old" setup while maintaining 99+ percent accuracy rate when filtering SPAM emails only through cloud mark platform alone; no need anymore expensive server hardware upgrades nor additional bandwidth costs required since most important part now lives inside Google infrastructure instead within my own data center(s) where cost effectiveness has been greatly increased thanks not just.
