[MM3-users] How can I remove anything added by Mailman 3 to the forwarded email

I need to use Mailman 3 exclusively for forwarding emails to my customers divided by type.

The emails must arrive exactly as they are, without any additions, and the lists are managed only by me: the customer ignores that he is subscribed to a list and receives the message as if it were one to one.

How can I remove anything added by Mailman 3 to the forwarded message, therefore also the links for managing my membership (unsubscribe and modify)?

Thanks a lot, Luca
