Need help - custom notification email

[cheatopia]

Good day,

I would like to know how to customize the email sent to paid subscribers, reminding them that their vip subscription is about to expire. I would like to add some text or links on the email. I don't know how to do it. The default message is this:

-----------------------------------

Dear xxxx,

Your access to the paid subscription "VIP ACCESS xxxxxx" is about to expire.

If you have selected a recurring subscription you will be automatically billed for the renewal, else to renew this subscription you must visit http://www.xxxxxxx.com/payments.php

If you do not extend your subscription, access will be removed.

-------------------------

I want to add more text on it or an extra link. How should I go about it?

Can anyone please help? Thank you very much!
