Design System

A design system is a shared set of reusable email building blocks and rules your team uses to create emails. It keeps layouts, styles, and code consistent so you can build emails faster.

A design system is your team's shared kit for building emails. It holds common pieces like headers, buttons, and content blocks that always match your brand. Instead of starting from a blank screen each time, you grab the same trusted parts. This keeps your emails clear, simple, and easy to scan.

A solid design system saves time and cuts down on mistakes. Your team can go from idea to send much faster because the layout, code, and styles are already agreed on. It also makes testing easier since the same components get used over and over. That builds confidence that your emails will look right in different inboxes.

To get started, pick one common email and break it into a few simple pieces. Create a standard header, a couple of content blocks, and a footer, then write down basic rules for fonts, colors, and spacing. Use this small system for a few weeks and adjust it as you learn what works. Over time you can add more parts as your needs grow.
