Thank you Lap for your quick answer!
In MailChimp I have a List with two groups: B2B and B2C.
And from the website I just only want to register Clients B2C, so I want when an user writes their mail and click SEND, it goes to a Group within a List.
I don’t want they have a checkbox to choose, I want it straightforward.
I can only see the Lists in MC for WP => Forms => Settings:
“Lists this form subscribes to: ”
But I cannot leave checked the specific group.
Can this be possible? I don’t want to have to do it manually every month.
Thank you again for your help!
