Your problem
My problem is:

There are multiple values in List-Unsubscribe header of the emails send through Mautic:

unsubscibe
unsubscibe2752×146 24.7 KB

I suspect due to this Gmail is not showing the unsubscribe button which it normally shows right next to the sender email address.

Does anyone know how to fix this?

Thanks
