If you try to confirm your Reddit.com mail in 2018 and you get error message:

not found

in the browser this means that you are not logged in Reddit. In order to confirm your email and account ensure:

  • that confirmation link is open in the same browser where you are logged in Reddit
  • log in and then copy paste the confirmation mail

In case of a missing mail you can:

  • ensure that registration is complete - process of registration could be confusing and I wasn't signed up the first time
  • ensure the correctness of your mail
  • Check your mail SPAM folders

If the mail is still missing then you can try to resend it and wait for some time. If the mail is not confirm they will show you reminder in the site.
