There are several things that you should check to figure out why your emails are not being delivered to a specific folder or label:
- Check the email routing settings to make sure that the folder or label is properly configured.
- Make sure that the email in question meets the criteria set to deliver the message to the folder or label.
- Check the message headers to see what is being used as a filter.
- Verify that the email address is correct, up-to-date, and active.
- Check for any anti-spam or malware protective filters that may be blocking the email from being delivered.
- If none of the above help, contact your email service provider for assistance.
