Your instance admin can see it. It’s not public though.
thanks!

Wait, I had to verify my email. Was there an option to not somewhere?
Email requirements for registration are set per-instance. Beyond that, it’s my understanding that only a user’s existence is shared across instances, in order to attach you to your content. Your registration details stay on the instance you belong to.
Some instances require it and some don’t.
What about messages? Where do they live and can they be seen by anyone?
Much like reddit, facebook or other apps with dms, only the instance owners (of the instances the users belong to) can see them. They aren’t encrypted. There was some work on e2ee messages on the Mastodon side but it stagnated.
Support question, please see rule #3 and !lemmy_support@lemmy.ml
if your worried getting spammed with emails, i’d suggest using an email relay in your Lemmy account instead of using your primary email add. Here is an example - https://relay.firefox.com/
