Receiving duplicate emails for the same updates

Hi Team,

I have written the groovy script for MessageTypeCd ORA_SVC_RESPONSE and ORA_SVC_CUSTOMER_ENTRY.
When there is a message updates, it give the notification only once. However, when we send the email communication, the email are duplicated now. One is without any link or format and another one is the groovy script template.

How to disable this email notification template and lets use only the groovy script template.

Thanks.
