Dark Mode Preview

We have added a new Dark Mode Preview toggle to the builder's preview mode.

This allows you to simulate the experience of rendering designs on devices with dark mode enabled.

What is Dark Mode?

Dark mode is a device or application-specific setting. When enabled, it causes text and transparent image content to display with a light-colored scheme on a dark-colored background.

Please keep a few things in mind while using this feature:

• Our goal here is to assist you in detecting design elements that may not render well in dark mode. This feature is intended to provide a general approximation of the dark mode experience. For this reason, we still recommend additional email client rendering tests.
• We've thoroughly tested our standard content blocks with this feature, but Custom HTML and other custom content blocks may render differently.

In our efforts to create a reliable dark mode preview, we've identified three main scenarios that may occur when an email client has dark mode active.

Nothing Changes

This generally applies to Yahoo mail and Gmail webmail. In these cases, email rendering doesn't change in dark mode. Instead, the email client UI's color scheme is shifted.

Partial Color Inversion

This generally applies to outlook.com. In this case, the email client detects light-colored sections and inverts them into darker colors.  

Full-Color Inversion

This generally applies to the Gmail mobile app and iOS 13 platforms. This is the most destructive dark mode scenario that creators most often need help with. In this case, light colors become dark and dark colors become light. For this reason, the dark mode preview feature is primarily designed to simulate this experience.
