I had 7 users using just email. I cancelled GSuite last month after being on the free tier for 15 years and not wanting to pay $6 a month per person. I went through the pain process of creating everyone in the family new Gmail accounts and using Google Takeout so I could transfer everyones email etc to their new accounts and then I set up Google Domains email forwarding to these accounts. I took me all day to setup separate device passwords for everyone.

Its was not a fun process
