I'm in the process of transferring my Wordpress website to a SquareSpace platform. Until I finish working out all the kinks, I want to set up a landing page with a subscription box so interested people can stay in contact. The issue is, I cater to 2 segments: Relationships and Mental Health. Is there a way to give the audience a choice as to which mailing list they'd like to be on? I don't want to send them emails they may not be interested in.
