This tool is amazing, I use it all the time! I first thought it was for spam, but now realize it's more for phishing emails, which are a lot more dangerous. There have been many times when I've been unsure of an email - now I just check it with Retruster, and get my answer immediately, along with plenty of helpful information. I've picked up many phishing emails, any one of which would have been disastrous had I not realized it was a fake. Highly recommend.
