Thank you both for your support. However, I still am not able to find the specific template that I need to change the content of.
Every time a subscriber changes his/her account information (name, address or password) the email template sent to the subscriber is somewhat messy, without proper wording.
Only if I find that email template that is sent to the subscriber upon changing account information, I would be able to customize the content that I want the subscriber to see in the email.
Any more help would be helpful and appreciated.
I have digged into each and every email template available in my hostgator directory, but failed to find that one specific template I need.
