As other people said, getting the mail delivered is the hard part. Check if your mail is received by Google, Microsoft, because apparently they blacklist by default.
You can do everything yourself and then set up a relay for sending, so all mail is sent through someone else who can make sure it is delivered. Then you could get something like purelymail, which is 10$/year to deliver your mail.
(I have no relation with purelymail, I am their customer, but it took me quite a while to find a mail relay that is not for sending bulk spam but for real people).
