HawkOpen writes the notice in English, Polish, German, Spanish, French, Italian or Portuguese, picking the language from the text of the email. When it cannot tell, the notice is in English.
Opening the link refuses tracking by the sending company at once; that company cannot switch it back. Separately, every email sent through HawkOpen, tracked or not, ends with the line “Do not send me messages”. No setting or plan removes the notice from a tracked email.
Where rules that require consent apply, tracking may start only after that consent has been obtained. The link in the message lets the recipient withdraw consent later.
