Hi Muhtashim,
Please check the following:
1. Is the pdm_mail process in running state when you run pdm_status?
2. Auto Notification setting on the Initial Activity notification is set to Yes?
3. The Mail settings are set correctly?
4. The contacts have correct email address
5. Are there any errors in stadlog relating to pdm_mail? if yes, what are the errors?
6. Are you able to send mail via pdm_mail command?
Hope this helps?
