How to send mail in groups in mailbox

How does the mailbox send messages in groups? The number of messages that can be sent by each email varies according to the allocation of the system, and there are two main influencing factors: mailbox package configuration and mailbox address reputation.

1. Mailbox package configuration: email mailboxes can be roughly divided into two categories: free mailboxes and paid mailboxes. The amount of mail sent by a paid mailbox is higher than that of a free mailbox. Usually, dozens of messages are sent at a single time in a free mailbox, and the single message volume of a paid mailbox is distributed step by step according to the package (take 163.net mailbox as an example, a maximum of 400 emails can be sent at a time).

2. Email address reputation: after each email address application is successful, the system judges its reputation according to its usage and the network associated with other mailboxes.

For example, if an email address often exchanges messages with multiple other email addresses, and there is no violation, the system will judge it as a highly reputable user with less restrictions on the effect of sending messages; while an email address that frequently sends spam or illegal content is reported by multiple other email addresses, it will be locked and restricted by the system.
