emailSpoofTest.com is much more than an ordinary email test

I think emailSpoofTest.com is much more than an ordinary email testing tool. My experience as a customer and the ease of use is wonderful. 

I thought we only had a small email security problem. EmailSpoofTest.com revealed so many email cyber threats we were open to. We used emailSpoofTest.com to systematically remove all the issues and since then we receive less than 0.01% spam emails and we no longer receive any phishing or spoofing emails. This is surely a relief for us as we operate in a sensitive health business. 

From the point of security issues, we have been permanently under attack for around 1-2 years. The attackers are trying to infiltrate our network and concentrate on phishing attacks. We needed to secure our email workflow and make sure the email communication is not interrupted by wrong or poorly configured email servers of our partners... I needed help with understanding how I could harden our email server.
