PDHengineer wants to send you only the email you’d like to receive from us. We try to keep our subscribers informed and entertained, so we categorize our emails into several categories allowing you to select what you’d like to receive. By the way, the vast majority of the emails we send are not sales-related — instead, they contain articles and blog posts that our subscribers enjoy. Set your email preferences here, and we’ll get the changes made promptly. Remember, if you ever want to change what we send to you, you can always request that change.
