We need a way for contacts to resubscribe to our email list if they unsubscribe via the new LC email unsubscribe link.
This will be useful for agencies so we can test the unsubscribe link and resubscribe after testing.
It will also be useful to give contacts who unsubscribe the option to resubscribe in case it was an accident or if they change their mind.
There could be an option to resubscribe given immediately after someone unsubscribes. This is a very common way to do it. There should also be another way to do it if the contact wants to be resubscribed and no longer has access to the email.
