How to send e-mails to corporate mailboxes in groups?

Corporate mailboxes are also divided into free corporate mailboxes and paid corporate mailboxes. Whether paid or free, there is an hourly delivery limit, and the daily delivery limit is also limited. Be careful not to send mail that exceeds the limit.

You can send it directly on the web page, select your customer's email address, edit the content and send it directly. One disadvantage of sending pages is that you can't control the sending speed and the content can't be changed. Sending the same content all the time is easy to be found by mail service providers, and it is easy to rebound and trash can. If you send it to customers one by one, you will be very tired and you won't be able to send many emails a day.

It can also be sent on email group software. The email group software will have some auxiliary functions. I have used biplane software before, and it has many functions. You can set the daily delivery volume and hourly delivery volume of a single mailbox, and you can send multiple contents in turn, cross delivery, sequential delivery, etc. It is quite convenient to send different contents and titles, add your company email address, customer email address, and edit contents, without having to manually click Send all the time.
