If you are not receiving the code, start by checking your JUNK folder. If you are using an email address that is associated with a business, I have found that they sometimes completely reject the email. In this case, I suggest two options.
Option 1: Use a personal email account like Gmail, Outlook, yahoo, etc.
Option 2: (recommended) Instead of using an email, select the login with Google or Facebook option. This completely bypasses the need for email verification and makes it easier to log in to the site in the future.
