Pros / Cons
  • It’s often praised for giving organizations confidence that inboxes are protected with real-time scanning and advanced threat intelligence.
  • The process for logging into different devices is a bit complicated and time consuming.

  • An excellent service that despite the somewhat difficult initial curve in understanding all the functions and how to get the most out of it then really becomes a well-structured service with all the necessary functions to control and manage the sending of e-mails.
  • I wasn't able to completely refactor the integration before the cutoff, so now I have no automation and they deleted all my contacts and my templates, so I get to rebuild ALL of that from scratch.
