Introducing MailingUI

An open source collection of email components and templates

We're excited to announce the release of MailingUI, an open-source collection of email components and templates to help you save time building transactional emails within your system.


Webscope.io (opens in a new tab) has delivered many complex web portals and mobile applications over the past few years. We've also refactored many legacy systems. We've identified some common pain points in building SaaS products during this period. Building and maintaining transactional emails is definitely one of them.

Building emails, especially in the old times, using HTML was hard and unmaintainable. Many developers just wanted to avoid it and hoped someone else would handle it. But let's admit it - emails are essential to almost all products.

Some great editors now allow you to create beautiful marketing emails. However, transactional emails are a bit different. You need to compose them programmatically and adjust them to various users. You need different things based on the system and user variables, support internationalization, etc.

Here are some of the facts that we consider the most challenging:

  • Reliable rendering in all major clients
  • Keeping emails consistent and composable
  • Support for i18n, dark mode, and other essential features

The good thing is that React.email projects solve many of these issues making the whole process much better nowadays.
