If your email doesn’t already include spam filtering; spam filtering services are a great option and will allow you to avoid the maintenance and cost of having your own in house solution.
This top 20 list is a list of the spam filtering services that rank in the top 20 results when doing a Google search for spam filtering service. There’s some on this list I’m not familiar with. This list is NOT an endorsement of any of these services. It’s just a list. I disregarded any paid ads and non-spam filtering service links.
All spam filtering services are listed in alphabetical order and there placement in the list in no way indicates which I think it better and since I haven’t used these all this list should not be confused as endorsing them. In the future I may have time to do a recommended list and some reviews on specific services.
