Troubleshooting DDI Emails

  • Updated

Here are a few suggestions if you have unsubscribed or are not receiving DDI System emails:

  • Visit this page to update your email preferences, including re-subscribing.

  • Open and click links in marketing emails you receive from DDI. This helps your account trust emails coming from our address and domain.

  • Move your marketing emails found in your SPAM/Junk folder back to the Inbox so these emails go straight to your Inbox in the future.

  • Add DDI’s from: email address (info@ddisys.com) to your email client address book. Each email client has a different process for adding email addresses, which can be found in their help documentation.

  • Request that your IT/Email team add DDI’s email sending domain and IP addresses to your allow list. This tells the email server to expect emails from any "from: address" containing our domain.
