If you are an Esurance customer, you should understand that there is only one way to pay an Esurance policy — through an automatic deduction from your checking or savings account or credit/debit card. So, you don’t do anything to make your payment other than to make sure your bank account has enough money to pay the bill (or your credit card has enough room for the Esurance charge).
If you want to change the date your payment is withdrawn, or otherwise manage your Esurance account, you can log in to your account at https://www.esurance.com/customer-login to make changes. The Esurance customer service phone number is 800-378-7262.
Note that the above information is only for insurance policies underwritten by Esurance. If you have a policy from an Esurance partner insurance company, you will deal with those companies directly.
