I built xdtmail.org mostly for myself to track who is not caring about protecting my personal info and/or selling it without my knowledge or consent. I've been using iCloud Hide My Email for a very long time and found a few things I don't like about it. It is really hard to manage these aliases - well hidden into settings. Forwarded emails are also lacking some signals like headers and often going to spam for no reason. Thus I built my own solution to my likings. Check it out anxd see if you find it useful for yourself. Open to comments/feedback.
