SpamTitan has a quick, easy initial setup as well as extremely responsive support. Any ticket I opened was responded to within 5-15 minutes and resolved within the day. Since implementation, we've seen a marked drop in spam/spoofed messages actually arriving in inboxes. We've also been able to migrate email hosts without difficulty or drop in service.

Some of the online guides have information that is outdated and can be misleading. For example, in their HostGator setup page here https://helpstc.spamtitan.com/support/solutions/articles/4000066181-setup-hostgator-mx-records-, the cloud7 and cloud8 MX records are given, which may be incorrect for new users on other clusters. It also calls for Remote Mail Exchanger rather than the correct Local Mail Exchanger setting in cPanel. Highly recommend using live support instead of guides.
