Modular by Design: A New Email System
Our Work
Conservation Law Foundation‘s Engaging Networks account ran on rigid, one-off templates, a problem most of our EN clients share. We replaced it with a system: one master template and 14 modular blocks, headers, buttons, dividers, a reversible two-column story block, that mix and match inside EN’s own editor with no code required. It’s dark-mode optimized, mobile responsive, and built on MJML for reliable rendering.
CLF needed better emails. We built a template engine instead.


The 4site team was a thoughtful and collaborative partner in this project. They were proactive in developing a solution that fit our needs and gave us the flexibility we were looking for, allowing our team to easily build more effective emails.
