I am getting mails from an unknown sender that will not answer requests as to who it is. How do I block them

Hi! Assuming you are using the Gmail app.
Open that mail, tap/click menu and choose ' mute'.
But best is to log in to your mailservie via your browser, to block a specific sender.
And you might consider this ... Gmail is offering the option to report a sender for spam.
