Define the Grid: Decide on the number of columns and rows. A common choice is a 12-column grid, as it offers flexibility. Create Modules: Design individual content blocks or modules that fit within the grid. These could include headers, footers, images, text blocks, and CTAs. Arrange Modules: Place the modules within the grid to create the email layout. Ensure each module aligns properly and maintains a balanced composition. Test Responsiveness: Check how the email looks on different devices. Adjust the grid and modules as needed to ensure a seamless experience.
