PDHengineer sends important emails to our users including copies of course purchase receipts, webinar access information, and valuable offers. We do not sell or rent our email lists to others.

We want to help you make sure these valuable emails are getting delivered to you. In order to help ensure proper delivery of emails to your inbox, you can add senders of legitimate emails to your whitelist, also called the Approved or Safe Sender list. Here are instructions on how to whitelist emails for several popular Internet Service Providers and email companies.

Please note that some corporate email servers mail erroneously filter email that appears to be SPAM, but is not. If you are still having difficulties after adding us to your Safe Sender List, please contact your corporate IT department for assistance.
