If you want to send email on the
wider internet today, you must have an account with Gmail, Microsoft, Protomail, or other main provider.
Running your own mail server isn't a possibility anymore. Even if you do jump through the hoops of SPF , DKIM , and DMARC with a dedicated $500-a-month connection there is no guarantee that your mail
will be delivered.
