When sending an email with WeChat, the email name should be written in the subject or title bar of the email. This is because the subject of the email can be directly displayed in the recipient's inbox, which expresses the content of the email concisely and clearly, which is convenient for the recipient to browse and identify quickly. At the same time, the appropriate email subject can also improve the opening rate and reply rate of emails.

When writing the subject of an email, you can describe the main content of the email concisely and clearly, so that the recipient can see it at a glance. For example, if you want to send an email about a project report, you can write "Project Report-Important Update" or "Project Progress Report" in the subject of the email. In this way, the recipient can quickly understand the key content of the email when he sees the subject of the email.

In addition, it can be explained and expanded in more detail in the email body, including explaining and supplementing the purpose, content and attachments of the email. In the text, you can use clear paragraph structure and appropriate format, so that the recipient can better understand and read the email.

In short, when sending an email on WeChat, writing the email name in the email subject or title bar can provide clear email information, which is convenient for the recipient to browse and identify, and explain and expand it in detail in the email body. This can effectively improve the mail delivery effect and communication efficiency.
