I too was the victim of having my emails not delivered, marked as unsafe, marked as phishing attempts, and it has looked awful to clients and vendors. The links I emailed to clients all redirected to a very bright red page warning them of danger and security issues. Now I have some crisis management to do about people thinking I'm a scam and hesitant to do business. I had to completely uninstall 'goemailtracker', and it took me a while to even figure out that it was the cause of all my woes. Very stressful morning.
