Managing E-Mail Lists - "Unsubscribe" functionality

Hi,
I am using monday to collect contacts / E-Mail addresses and to send out a sequence of onboarding emails to those email adresses.
I would like to offer every contact to “unsubscribe” from the thread automatically again - setting a flag for deletion to this contact. and onboarding e-mails.

Any idea how this could be acomplished?

Thank you !
Bernd

I have the same issue/question. Did you ever learn anything?

Same issue here.
Is there a way to add an unsubscribe button to a mass mailing?
