Overview

Emails are a crucial part of automated internet communication, used for various purposes such as account creation, invoicing, and event sign-ups. However, the process of creating and sending emails often involves dealing with legacy web technologies. In an effort to improve the developer experience, Escape has rebuilt their email stack using SvelteKit and MJML, allowing for dynamic and logic-driven emails. This article outlines their approach and the challenges they faced in making these technologies work together.

Features

Svelte-powered email rendering: Escape uses Svelte, a JavaScript framework, to write dynamic and interactive emails with logic and string interpolation.
MJML-based email templating: MJML, an XML-based email templating language, provides flexibility and power in designing email layouts.
Instant feedback loop: With the use of SvelteKit-powered dev server, developers can preview and test their emails with live-reload, improving productivity.
Compile-time type checking: svelte2tsx enables compile-time type checking for props, ensuring better code quality and reducing errors in the email development process.

Summary

Escape has rebuilt their email stack using Svelte and MJML, aiming to improve the developer experience in creating dynamic and logic-driven emails. By leveraging SvelteKit and MJML's capabilities, they have implemented a system that allows for easy email development, previewing, and testing. The use of svelte2tsx enables compile-time type checking, enhancing code quality and reducing errors. With this setup, Escape has overcome the challenge of making these technologies work together and streamlined their email development process.
