I can provide you with information about the Oracle Cloud Project Portfolio Management (PPM) API.

The Oracle Cloud PPM API allows you to programmatically interact with Oracle Cloud PPM to manage your projects, portfolios, and related data. You can use the API to perform various actions such as creating and updating projects, managing resources, retrieving project status, and more.

To ensure that your API requests don’t end up in spam folders when sending bulk emails, you should follow best practices for sending bulk emails through an email service provider or SMTP server. Here are some tips to avoid having your emails marked as spam:

1. Authentication: Ensure that you have proper authentication in place when sending emails through the API. Use API keys, tokens, or other authentication methods provided by your email service provider.

2. Sender Reputation: Maintain a good sender reputation. This includes sending emails from a domain with a good reputation, sending relevant and valuable content, and avoiding spammy practices.

3. Opt-In Lists: Make sure you have permission from recipients to send them emails. Use opt-in lists to collect email addresses from individuals who have explicitly agreed to receive emails from you.

4. Content Quality: Create high-quality and relevant email content. Avoid using excessive images, links to suspicious websites, or misleading subject lines.

5. Unsubscribe Mechanism: Include a clear and easy-to-use unsubscribe mechanism in your emails. Honor unsubscribe requests promptly.

6. SPF and DKIM Records: Configure SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) records for your domain to authenticate your emails.

7. Compliance with Regulations: Ensure that your email sending practices comply with email marketing regulations, such as CAN-SPAM Act (if applicable).

8. Monitoring and Feedback Loop: Monitor your email delivery and open rates. Use feedback loops provided by email service providers to identify and handle complaints.

9. Testing: Test your emails with spam filters and email deliverability tools to ensure they are not likely to be marked as spam.

10. Volume Control: Gradually increase your email sending volume to avoid triggering spam filters.
