Why do some companies put privacy text at the end of the email?

Question

Email

As far as I understand it has no legal force at all. So right?
Here is an example:
This e-mail and any documents attached to it contain confidential information and are intended solely for the use of employees of the company, individual or legal entity to which they are addressed. We inform you that if this message is not intended for you, the use, copying, distribution of the information contained in this message, as well as the implementation of any actions based on this information, is not allowed. If you have received this e-mail in error, please contact the sender and delete the e-mail and any files sent with it from your computer immediately. Thank you.
And so:
This e-mail and any attachments contain privileged and confidential information intended only for the use of the addressee(s). If you are not an intended recipient of this e-mail, you are hereby notified that any dissemination, copying or use of information within it is strictly prohibited. If you received this e-mail in error or without authorization, please notify us immediately by reply e-mail and delete the e-mail from your system. If you need any further assistance, please send a message to [email protected] Thank you in advance.

Answer 1

Who said that it has no legal force?) if you signed something and it does not contradict the law (and this is not just not contrary, but in the spirit of the letter of the law), then it has legal force)
This message informs you about the presence of specific parties for acquaintance with the document. You are not relieved of responsibility by viewing someone else's correspondence that came to you by accident. And further disclosure of it (for example). A good lawyer will tear you like a heating pad)
