Same as so many others:
1 for work
1 on yahoo for personal
1 on gmail with my name for job searches and quasi professional things
Oh - I just forgot, I do technically have 1 more, and that’s my spam attractor. I check it about once every 6 months and just purge everything in it. If I sign up for something free that I think will get me a lot of spam, it goes to that address.
