There's a long story here, but here's the short take: Most of my email accounts are public email provider mapped to domains. But anytime I sign-up for something that's not tied only to one of my work endeavors, I use the non-mapped address. So, newsletters, sign-ups, Amazon account, etc. I don't use any mapped domains for those things, as those kind of come-and-go. I segregate my personal email and my business emails from the @public-email-provider address, which I want to keep away from my other activities. It also puts all those mailing list emails, legal acknowledgements, etc., in one place as much as possible. I can filter and manage those in one place. I also don't have a strong sense of personal ownership of that stuff. It's like a PO Box, not my house address. I don't check that account for human- initiated communication. That's my personal address (which gets almost zero traffic these days) and my work/business email addresses. I have a strong aversion to the company behind public email provider. But I set a calendar reminder for a year out so I don't think about it much until then. I have some endeavors that will let me close up various business activities and centralize to one. If/when that's solid, I'll probably consolidate all my income-oriented business accounts and services [and probably somewhere else], but keep the public... as it's just a PO Box.
