Starting 2018.1 release, for any emails sent from NetSuite, the setup of Domain Keys Identified Mail (DKIM) is now required in order to display your email address in the From email header.
What is the reason for this DKIM change?
To protect customers from unsolicited email, many ISPs check the domain key used in an email message to determine whether it is spam or not. DKIM is a method of digitally “signing” your email to allow its authentication.
When sending email from NetSuite, using your own domain key increases campaign delivery rates and help enhance your reputation as a legitimate marketer. Without DKIM, you cannot send more than 10,000 messages in a single email campaign.
What will happen if I do not setup DKIM?
If you do not set up DKIM in NetSuite, or if you are using a free email domain on email sent from NetSuite, the email’s From header is rewritten. The original email address is moved to the display string. The SMTP-related email address in the From header refers to netsuite.com. For example, if domain keys have not been set up in NetSuite, the email’s FROM header would be savan.patel@jcurve.com.au <system@netsuite.com>.
Please see examples below of how your email header will appear for your recipient:

Note: The header may appear differently depending on your email preference in NetSuite.
