If you need to change your billing information, you need to sign into your “My Account” area. You can do that by clicking this link: https://account.iljmail.com/my-account
Remember that you don't use the same login as you do with your email account. You will have a username you chose upon sign up or you can sign in with your off network email address. If you can't remember your password there is a "Lost Password" link under the login form
Over to the left, you will see a list of pages you can visit.
Payment Methods – takes you to the place where you can change your credit card information
Addresses – takes you to the place where you can change your billing address
My Subscription – takes you to the place where you can see details about your subscription and allow you to cancel your account (we hope you don’t but sometimes it happens)
