Is there a way to link a 'free shipping' discount with the newsletter sign-in? I am using the Brooklyn theme. I am also using the Privy app for the newsletter popup. So I want to encourage signing up for the newsletter by offering free shipping when they sign up. Once they sign up I would like to continue offering them free shipping. Possible? Thanks.
I'm not sure if that can be done automatically. That's why in the majority of the cases store owners use discount codes to promote signing up on their newsletters.
