I have a hotmail that I just use when I sign up for stuff online or need to give an email anywhere other than to personal friends, family, banks, etc.
Been doing it for many yrs, works great. A lot of places online sell your email address so you get a ton of junk.
I think a good one is gmail as I have it too. Hotmail was hacked a couple years ago & started sending all my addresses emails selling something. I eliminated all my addresses so they couldnt do it anymore. Wasnt a problem as far as anything being stolen as there wasnt anything to steal from Hotmail.
