The https://mail.python.org/mm3/mailman3/lists/core-mentorship.python.org/
link should open in your browser (or copying and pasting it into your
address bar should get you to the web page), and from there you can
either create an account ("Sign Up" link in the far upper right
corner) or subscribe without an account at the bottom of the page,
which will allow you to send email to core-mentorship at python.org and
receive replies.

For this (docs at python.org) mailing list, you can subscribe using the
middle section of https://mail.python.org/mailman/listinfo/docs

I can't change where I've already used your name (or where it's
already attached to your messages to this list (see
https://mail.python.org/pipermail/docs/2018-September/thread.html),
but I can just use ZooDSS from now if you prefer :)
