Modular design systems have been prevalent in the email industry for a long time. They’re made up of a series of reusable modules that can be combined in various configurations. Basically no one wants to build endless one-offs and this streamlines the email creation process. Whilst 10 – 20 modules is fairly typical the largest we designed recently had 37. These systems can run quite large and involve a lot of information that needs to be organized in a consistent way. One change to my process that helped me manage was the adoption of a typographic grid. Having a size and spacing system that unites all the elements not only made for more ordered layouts, but a saner more efficient process.
