How do I make sure email from PESI, Inc. is not delivered to my Spam or Junk folder?

You can proactively make PESI Inc. a "Trusted Source" by adding our "From Address" (customersupport@pesi.com; info@pesi.com; courses@pesi.com; support@pesi.com) to your address book, contact list, or safe sender list.
If you find a PESI Inc. email in your spam or junk folder, many email programs allow you to mark the email as a "Trusted Source" by clicking "Not Spam" or "Add to Safe Senders List" which will allow future PESI Inc. email to be delivered directly to your Inbox.
