What causes manually-sent emails using Email Templates, to no longer succeed in sending, and to show up in the Sent Emails List as Not Sent and Compliance Verified = No?

AI generated answer (using internal Slack threads):

Based on the conversations, there could be several reasons why manually-sent emails using Email Templates are no longer succeeding in sending and showing up in the Sent Emails List as Not Sent and Compliance Verified = No: 1. DKIM Setup: Check if the DomainKeys Identified Mail (DKIM) is set up and properly tested in Email Preferences. DKIM is an email authentication method designed to detect email spoofing. If it's not set up correctly, it could prevent emails from being sent. 2. Email Preferences: Make sure the test email address is added in Email Preferences > Sandbox and Release Preview after the last refresh. If the email address is not added, it could prevent emails from being sent. 3. Duplicate Emails: If you are sending multiple emails with similar or the same subject, NetSuite might block them as potential junk. Try adding a unique value in the subject to avoid this issue. 4. Scripted Records: There might be some scripts triggering the error. Check under Customization > Scripting > Scripted Records to see if there are any scripts that could be causing the issue. 5. External Customer Form: If the 'send auto reply email' option is checked in an external customer form, it could cause issues with email sending. Remember to check all scripts and workflows running on the records and the status of the workflows. Also, check the system note/workflow history for any potential issues. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
