How do you get the email address from a Minecraft account?

Hi, I've been using a username for 4 years, but it had xX at the beginning and Xx at the end, reason: The name was already taken, so I had to add special characters, I don't want to change the name now. So when I search for the name on namemc.com, it says that someone rnd has owned the name for 5 years. This seems as if it has not been online for a very long time. So I wanted to write to him by e-mail, but I don't know how to get it out. Can you even get it out or would that be illegal with all the data protection? If you have solutions, how do I do it now

No, you can't get that out. And how do you know if he's active or not? Namemc doesn't say that anywhere.

I had been missing the name for 5 years and tried it every week xd Besides, he has a Steve skin, most players usually already have a skin. You could ask who he was still active

You can't get it out
