This topic includes troubleshooting tips to determine why email messages from NetSuite are not delivered.
If an email message to one person was not delivered, go to Lists > Relationships > Bounced Email Addresses. Determine if the recipient is on the bounced email list.
Go to Setup > Company > Communication > Sent Email List or Lists > Mailing > Site Management Tools > Undelivered Emails. Find the email address and look at the value in the Compliance Verified column. If the email address is not compliant, check the DKIM settings for your account.
If the Compliance Verified column is set to No, go to Setup > Company > Email > Email Preferences. On the Domain Keys subtab, set up a DKIM key for the domain populated by the customer in the From header of the email. You can set up DKIM keys for each domain you use in the From header, but only one DKIM key per domain. When you send an email message, NetSuite uses the DKIM key that best matches the From domain in the current email message.
