Email aliases via proton or tuta paid - using custom domain from cloudflare, following bazzell ebook

ive done similar. anonymous ownership of domain via njalla, dns with cloudflare as SpamHaus blocked me within a year or so because of the dns records for whatever reason, and use tutanota & simplelogin. very easy to do. i prefer tutanota simply because of the direction proton is going, as well as how theyve handled matters in the past.
