Wrappers consist of a header file, footer file and CSS (Cascading Style Sheets) which is built into the code to dictate font sizes, styles, colors, etc. Using wrappers typically replaces the need to apply general styling to the text within the email body. However additional styling can be added to the email body through the email editor. The header and footer files typically match your branding material such as your website, winery logo, labels, etc. Each database can have as many wrappers as you would like. It's common to have seasonal, promotional-themed and department specific wrappers for the Tasting Room, Wine Club, Allocation, etc.
