Google is starting to levy requirements that one-click unsubscribe is available for all mass emails. Otherwise the emails will be automatically marked as spam.
This is a big deal for anyone who sends out marketing mails via their website, or other mails that might be construed as mass emails.
To support the one-click unsubscribe, there has to be an endpoint on the website that accepts it.
To set up one-click unsubscribe, include both of these headers in outgoing messages:
List-Unsubscribe-Post: List-Unsubscribe=One-Click
List-Unsubscribe: <https://solarmora.com/unsubscribe/example>
Please upgrade Forminator Pro so we can generate the needed backend for the List-Unsubscribe link to gather the emails. This cannot require a button click as that would break the requirement.
