@lokeshvyshnava2 I gotcha. Based on what you are describing then, I unfortunately don't think this is possible. The purpose of the email template is that is standardizes the look and feel of notifications. So the only way to edit them would be to change that configuration in the system using the "admin" role. If you are using the Email Client, you can send "custom" emails that contain whatever you want, but all system generated notifications cannot be edited before sending.
If you have a screenshots or more info, maybe that can help provide a better answer.
