These can be physical items that you send to customers, such as flyers, promotional flyers, or catalogs. But also digital marketing materials that use the internet / social media to attract consumers and communicate the product range to a wide audience. Examples of marketing materials include billboards, bus shelters, sidewalk sign posters, digital signage, social media banners, and web banners.
