** Failure to receive an email notification that your bill is available online does not relieve you of your obligation to pay your StarTex Power bill by its stated due date. Be sure to check and update your account online if you have changed your email address and have not notified us. You should receive a confirmation email stating that you have enrolled in Paperless Billing. If you do not receive such confirmation within 48 hours, please verify your account information or call our Customer Care Team at 1-866-917-8271 for help. You must provide a valid phone number when enrolling in Paperless Billing, so we can contact you about your account if needed.
