SpamTitan is very easy to use once set up, and very affordable. Support is responsive and it's easy to submit support requests or questions; they get answered within 24 hours or less. The set up process wasn't too bad either, and this was my first time setting up a spam filter program. Their sales reps and tech support people were very helpful in the process and they have a lot of documentation online to help you figure out how to set up everything correctly with different email servers. I wouldn't suggest doing it if you don't have some tech-savvy in you, but it doesn't require a dedicated IT department with years of experience. Review collected by and hosted on G2.com.
We are on SpamTitan Cloud. The most common complaint our users have is that the Quarantine report can only be emailed at most once per day, and it comes at about midnight our time (MST). That means any legitimate emails that got caught in the spam filter aren't seen until the next day. This can be frustrating when waiting for important emails. Unfortunately, on SpamTitan Cloud we are not given the option to adjust the time that this email is sent, and there is no option for it to get sent twice a day. It is at least quite easy for the administrator to log in to the spam filter and release any important emails - but we have to know that they're missing to do that, and it's frustrating for the user to have to ask and hope that it's in there.
If that's something that would be a deal-breaker for you, I suggest going with their other version (I forget the name) that allows more customizing of the quarantine email option. I believe it's a bit more expensive but gives you more control.
Outside of this issue, it's been pretty great! Review collected by and hosted on G2.com.
