According to Litmus’ Email Client Market Share, in 2022, an average of 35% of opens tracked utilized Dark Mode, indicating a consistent year-over-year adoption rate.

Dark Mode has firmly established its presence in the inbox. However, ensuring that emails appear appealing in this reading environment poses a considerable challenge for email marketers. Let’s talk more about email dark mode in detail in this beginner’s guide.

What is Dark Mode Email?

Dark mode changes the color scheme on your device, usually flipping white backgrounds and black text to black backgrounds and white text.

In 2019, Android and iOS implemented their respective dark settings, called Dark Theme and Dark Mode, which led to the widespread adoption of this feature by numerous popular apps such as Gmail, Facebook, and Microsoft Office. The dark settings offered by these operating systems influenced other developers to incorporate this feature into their own applications.

Certain email clients have the capability to automatically enable a “dark mode” feature. They achieve this by examining the presence of defined text and background colors, targeting specific CSS properties and HTML attributes, and adjusting them accordingly to create lighter or darker shades as needed.

Why is Dark Mode Email Important?

According to an Android Authority poll, out of more than 2,500 votes, 81.9 percent of respondents stated that they actively utilize dark mode in various settings such as apps and phones. Another 9.9 percent reported switching between light and dark modes, while only 8.2 percent stated that they do not use dark mode at all.

However, it may be more appropriate to inquire as to why individuals are drawn towards the use of dark mode.

Dark mode email has been found to enhance accessibility, especially for individuals with cataracts and other visual impairments. According to a study conducted by Nielsen Norman Group, using dark mode can result in improved visual performance for such individuals. Additionally, it suggests that long-term use of light mode may be linked to the development of myopia.

Switching from light to dark mode at 100 percent screen brightness has been found by researchers at Purdue University to save, on average, 39 – 47 percent battery power. This also benefits our phone batteries.

However, it is important to mention that the majority of individuals tend to utilize the auto-brightness feature on their smartphones, which generally maintains the screen brightness at approximately 30 – 40 percent. When set at these levels, the battery conservation is only around 3 – 9 percent, which is relatively inconspicuous for most users.
