SpamTitan

SpamTitan has a high level of consistency when it comes to preventing spam and malicious communications from reaching my primary inbox. Setting up the specific keyword that I want to be used in the blacklist keyword and the whitelist keyword is quite easy. After setting it up, the procedure is streamlined, and I would not have to keep track of it because it would send me a weekly report.

There have been times that a legitimate email has been blocked and no message has been received to inform me about this practice, resulting in the email remaining in the junk inbox until I manually search and whitelist it. For the first time, adding a domain to the app can be daunting, and I had to seek assistance.

Price is extremely reasonable for the service they provide. The competition has slightly more features but they offer them at 3 - 5 times the cost per user, which is in no way justifiable for the benefit (if any). Very easy to setup and offers great flexibility in how emails are filtered for different users.

One feature that is currently missing that our previous spam filter solution had was the ability to whitelist and blacklist email address and domains directly from the mail history report.

Was easy to implement and, as the title said, it worked great until it did not.

This is a cloud-based product. In early August, the product totally failed. (it was a Friday morning in the US, but dont remember the date as we have moved on to an)other product). Just noticed that we were no longer receiving emails. Rerouted DNS to cut SpamTitan out of the loop and email (unfiltered) started flowing. Contacted Spam Titan and they confirmed that the cloud instance on which we were running was offline for unknown reasons.
Our business is 24x7. We ran without Spam Titan on Friday, and Saturday, and Sunday, and Monday. We called for updates, on Friday afternoon, Saturday, Monday, and Tuesday. Each time, there were no updates and were told that we would updated by email and by phone if we left our best contact number.
Well, that never happened. Interestingly, we were not offered to route through any other web-instances.
By late Tuesday, we had already vetted another product and moved our production platform to the new provider.
Their support SUCKS. Moreover, I am going through the same goat-ropin' with trying to cancel my subscription. If you call them and make the appropriate selection, you always go to voice-mail (again, no callbacks). If you select "technical support", they have to connect you with Customer Service (one time out of two tries, I got a live CS person and they told me that they would have to connect me with "retention". Again, no one was available but was promised that someone would call me back -- never happened.

SpamTitan has a very good accuracy in filtering a spam and malicious emails from entering my primary inbox. It is very easy to set up my own keyword that i want to include in the filter keyword and setting up the whitelist keyword. After setting everything up, the process is automated and i don't have to constantly monitoring it as it will sent me report for every-week activity.

There are time that a legit email will be blocked and there are no notification sent to remind me about this activity, and resulting that email stayed in the spam inbox until i have to manually check and whitelist it. Adding domain into the software for the first time can be confusing and i had to ask for a support to fix it.
