The CMDB (Configuration Management Database) is an essential application in ServiceNow that helps organizations manage their IT assets and configuration items. To ensure that emails related to CMDB applications in ServiceNow do not go to spam when sent in bulk, you can follow some best practices similar to those I mentioned earlier:

1. Sender Reputation: Use a reputable sender domain and email address associated with your organization to send emails related to CMDB applications.

2. Authentication: Implement email authentication protocols like SPF, DKIM, and DMARC to validate the authenticity of your emails.

3. Content Quality: Create professional and relevant email content with clear subject lines, avoiding spammy language, excessive capitalization, or image-heavy emails.

4. List Quality: Keep your email list up-to-date by regularly removing invalid or inactive addresses and ensuring that recipients have consented to receive emails.

5. Consistency: Maintain a consistent email sending frequency and content to avoid triggering spam filters.

6. Opt-Out Mechanism: Include a clear and easy way for recipients to unsubscribe from your emails.

7. Test Emails: Send test emails to a smaller group before bulk sending to check for spam issues and make necessary adjustments.

8. Engagement: Encourage recipients to engage with your CMDB-related emails, such as clicking on links or responding to messages.

9. Monitoring and Feedback Loop: Monitor email delivery rates and track spam complaints. Use feedback loops provided by email service providers to address issues promptly.

10. Compliance: Ensure that your email campaigns comply with relevant anti-spam laws, such as the CAN-SPAM Act or GDPR.
