1. If it's a China Merchants Bank credit card, you can fill in a QQ mailbox or a Netease mailbox, such as 1234@qq.com, and change the previous number to your own QQ number.

2. The bill-receiving mailbox is literally used to collect bills. For example, if you apply for a credit card, you need to fill in the bill mailbox, and the bank will send the credit card bill to your mailbox in the future. This is an electronic version.

3. The billing email address can be QQ email address, Netease email address, etc. Different mailboxes have different suffixes, for example, the suffix of QQ mailbox is @ qq.com; Netease mailbox suffix is @163.com.

That is, the electronic bill receiving mailbox:

When applying for a credit card, there will be an item in the mailbox. This mailbox is mainly used to receive electronic bills of credit cards, so it will be called electronic bill receiving mailbox. The e-bill receiving mailbox will receive the current credit card bill sent by the bank on the bill date, and you can quickly query the bill information or related policies after logging in the mailbox.

E-bill receiving mailbox can receive e-bills for free. Although some credit cards do not need to apply for e-mail, the display of electronic bill information is very comprehensive. When applying for a credit card, you need to fill in an e-mail number to receive the electronic bill.

Second, how to modify the bill-to mailbox:

As many cardholders know, when applying for Guangfa Credit Card, there is a required email address in the application form, which is mainly used to receive electronic bills. No way, because Guangfa Bank has stopped issuing paper bills, so I can only tell you the monthly bills in this way.

If the user changes a new email address, the reserved email address must be changed to the existing email address in order to receive the monthly electronic bill smoothly. This modification method is very simple. Just log in to Guangfa Online Banking and select "Credit Card → Card Management → Bill Sending Method" to modify the mailbox.

3. Unable to receive the bill after modifying the mailbox:

Generally speaking, there are several reasons why you can't receive an electronic bill after modifying your mailbox:

1. The email address modified by the user is incorrect, which makes the system unable to deliver the electronic bill;

2. Some mailboxes are very unstable when receiving electronic bills, and may be rejected. It is best to use Netease mailbox or QQ mailbox to receive electronic bills;

3. E-bill mail is judged as spam or advertising mail by the mailbox, and users can look it up in the mailbox. If yes, set the sending address of Guangfa Bank as the mailbox white list, and it can be received normally;

The electronic bill hasn't arrived yet. Under normal circumstances, Guangfa Bank will send the electronic bill within 2 working days after the bill date, so please pay attention.
