Our business sells two different product categories (games and apparel). We'll be selling both categories from one website. However, we want our customers to be able to opt-in or out of the different EDM lists for games and/or apparel. Is anyone familiar with any apps or coding that we can use to create a newsletter form or pop-up that has multiple checkboxes that our customers can select to streamline them into the respective mailing list? An example of the form below for womens vs menswear mailing list.
