a potential hosting provider is requiring a specific form of one-click unsubscription link/button for all sent newsletters, as per https://www.ietf.org/rfc/rfc8058.txt and as part of the CSA (certified senders alliance) standard, which in turn whitelists newsletters for some larger email providers.
So my question is: can this be done with phpList?
This is the example they give:
And this would be the post request generated:
POST /unsubscribe.html?opaque=123456789 HTTP/1.1
Can phpList work with such a post request variable and directly unsubscribe a user without him having to click another button?
Thanks for your help!
