You have the ability to turn off receiving all emails from Deltek Collaboration inside your user profile. To access your profile, click on your picture or name in the upper right corner of Deltek Collaboration and choose My Profile. Click the “Notifications” link at the top. Check to see if any of the envelope icons are showing as black (enabled). If not, click the icons of the items you want to receive emails for to enable notifications.
Another reason you may not be receiving email notifications from Deltek Collaboration is that the emails are being caught by your spam or junk mail filter. We recommend checking that filter and then approving (adding as a trusted sender, white-listing) the Deltek Collaboration domain for sending emails to you.
