Can the sender see the withdrawal mail from QQ mailbox?

This may not be right, but we can estimate the probability of seeing it.

If the other party hasn't opened it yet, the mail withdrawal is theoretically invisible to the other party.

But there are several special cases:

1, the other party opens the email, and the SMS notification has arrived. This notice can see the 70-word email content or email subject.

2. The other party has started the client (including computer and mobile phone client) to receive the mail. If you have just received an email during this time, you will be prompted that the email has been successfully withdrawn, but the other client already has an email and can see it.

3. The other party turns on the automatic forwarding function or other mail collection functions. As soon as the mail is received, it will be forwarded or received by another mailbox, and the mail will be available.

Precautions for sending mail:

1, the email must be marked with a title, and many people decide whether to continue reading the contents of the letter in detail through the title. In addition, the email title should be as descriptive as possible, or the main idea related to the content, so that people can know it at a glance, so that the other party can understand and remember it quickly.

2. If you are not the object of frequent communication, remember to write an email to address each other to show politeness and attract the attention of the main recipients.

3. Recipients should use their full names in Chinese as far as possible, and avoid displaying only personal e-mail accounts.
