Please Welcome The NEW Litmus Dark Mode Coding Experience + Visual Impairment Filters!


Drumroll, please! We’ve got some shiny new features in Litmus! Our latest product launch is an exciting step towards more accessibility, more options, and greater flexibility when it comes to everyones favorite experience… Dark Mode! (Emo hairflip and all.)

Let’s open up the latest Litmus product launch box and take a look at the new Litmus Dark Mode coding experience, and the Visual Impairment Filters that go along with it. 

The Dark Mode Coding Experience

The short version: Litmus Builder now includes a feature that will check if your email contains best practice elements to define your Dark Mode view, and help you optimize it if not.

What is Dark Mode coding?

With our new Dark Mode Coding Experience, Litmus checks to see if a CSS color-scheme element exists in your email code. If the element is detected, you’ll see a browser preview of the Dark Mode experience. If the element is not detected, a notification will pop up and provide step-by-step instructions on how to add it, snippets to copy or save, and best practices to keep in mind as you build. This feature is available on all paid plans. 

Unleash the night, embrace the Dark (Mode)!

Benefits include…

  • Faster testing and code QA when it comes to ensuring your emails are optimized for the Dark Mode experience
  • Access to Dark Mode coding best practices and out-of-the-box code modules created by Litmus email geeks 
  • Easy access to the Dark Mode experience + the ability to view and optimize it on the fly

Visual Impairment Filters

The short version: Litmus now includes Visual Impairment Filters, which allow users to toggle between red, green, blue, or monochromatic color vision deficiency filters.
