Email Issue

Hi, I am not able to send more than one time email on the same ticket after being modified. After the creation of new case ,when I update ticket , it sends email only for the first time but when I once again update ticket then I don’t receive email from crm.

The case update email will be sent if you have enabled the AOP.
Go to Admin -> AOP Settings enable the “Enable AOP” and provide necessary details.
Set the email templates as well.
