I’m seeing lots of people subscribing with their real email address to different newsletters or random websites that they might use once in a while.
For a couple of years I have run a proxy SMTP that I kept to forward emails to my real address, as a privacy measure.
People tend to use the “+” sign in order to identify if their address was sold, for example signing up with “michael.john+amazon@gmail.com”, now what most do not realize is the fact that when selling data to third parties, most companies parse their email lists and clear our those “+” sign. (Source: I have worked with companies that do that)
I found the relay from Mozilla to be massively useful in this case, so if anyone is interested, have a try with it:
As a side not: If you’re using firefox, it integrates nicely into your browser, right clicking on a field and selecting “Use relay mask” is enough to generate an instant address so you can easily rotate them for each service.
I’ve got a cheap VPS to act as a relay with a static, more or less trusted IP address. It just forwards incoming mail to my homelab, and outcoming mail to the recipient. The setup can get pretty complex if you haven’t done this before.
Would probably be a lot easier to just deploy addy to a vps and call it a day
