Modular email design takes a master template approach to your email's design and code and offers a reusable framework for a more efficient workflow. It improves the quality and consistency of your campaigns while saving you time on common, repeatable email production workflows.
This guide covers what's involved in developing a modular template system for your email campaigns. From design, to code, to managing updates to it.
While setting up a modular template system requires some up-front work, it simplifies your day to day workflow, saving you a lot of time in the long run.
Your company brand should have a style guide for all communications, both visually for your creatives and verbally for your copy. A modular email template would utilize the style guide and go even further in keeping your campaigns consistent in tone, quality, and overall user experience.
A template should use modular self-contained pieces, typically consisting of:
Components are the building blocks of your content and should work by themselves in a range of contexts. Regions are content pieces and components arranged in a specific way. And, Sections are full-width horizontal containers stacked on top of each other to create an overall layout.
Keep this hierarchy in mind and introduce it to your team as you design and build your templates. Having an underlying foundation allows everyone to better organize what they're already doing and essentially speak the same language throughout your email's workflow.
Some elements that make up an email template and how they work modularly.
