Proton is sort of abundant, you can create a shit ton without tying a phone number to them but recovering a lost account is a nightmare. I lost all of my e-mails once because when you try to recover it and you don't have the proper methods, they scrape everything off

Because this is Linoox Occupied Board, there is bound to be transsexual retards recommending e-mail services that don't even get accepted by any service or site btw

The best e-mail service unironically is one of the big ones, Gmail or Outlook. I tried Yahoo once, but just to see how it worked and so on
