If you're expecting an email from PNP but haven't received it yet, start by looking in your spam or junk folder. Your email service may not recognize PNP's email address and mark it as spam.
If so, tell your email reader application "this is not spam" by adding PNP's email address no-reply@portablenorthpole.com to your list of contacts or list of secure/verified senders or by clicking the "this is not spam" or "this is not junk" button.
