I built dark mode for an email client’s (shortwave.com) HTML emails and this was the last major hurdle to solve. I wish that had existed then :)

Generally making emails dark mode is a non trivial problem, there is an hope source library that is a good start from Tempo: https://github.com/yourtempo/tempo-message-dark-mode

However there are plenty of edge cases that plugin doesn’t handle that we had to fix at Shortwave. Examples include legacy HTML4 attributes, better support for emails that are half dark mode, emails that have background images of #fff (looking at you google play reciepts), the list goes on. It’s honestly pretty solid now
