I would definitely want to jump right in if I could use my own domain name. Plus, I have over 100 email aliases stored in my G Suite GMail account. I would hope I’m not the only one who use email aliases a lot for different websites, such as Purism, Bank of America, Wal-Mart, and many other businesses.
I want to de-Google-ize my life, but the only thing I can’t de-Google is YouTube. I watch a lot of let’s players. But I digressed.
Update: Actually, I realize that Purism Librem Mail does not store email messages in their server as it’s decentralized, so I’m looking at going with a different email service.
