Newletters refer to a tool used to communicate regularly with a retailer’s subscribers, delivering a certain message and news about the brand to their customers. These messages can contain simple text or structure composed of images and formatted text. Brands usually send newsletters to their regular customers to send out messaging on their new launches, mix and match ideas, collaboration updates and promotions that they are running so their customers are up to date with the current activities that they are doing, and attract customers to their website.
