Mail Assure is great!
- It does a good job of not having false positives.
- I really enjoy the flexibility of the filters.
- The cost of this solution is very low.
Cons
- I am waiting for the Outlook plugin as those are more similar to what we were used to.
- I wish there were links inserted at the bottom of each message to have a single link to train as spam or not spam instead of needing to export the email file and then use those files to train through their website (a single click is much easier than a complex set of actions).
- We have been able to set up Mail Assure so our essential email gets delivered and our employees don't have too much noise.
