Dark Mode In Emails: The Technology That’s Here to Stay

Dark mode is like the latest fad in the world of technology. Everyone’s talking about it and it has taken over all our devices in the past year. Whether it is social media channels or websites, people are trying out this technology everywhere.  To follow the trend, iOS Mail launched Dark Mode to its desktop email client in the year 2018. Later, in 2019, it also entered iOS Mail and Gmail.

So, what is Dark Mode?

In simplest words, Dark Mode is a reversal of the color scheme. This means that it displays light-colored typography, banners, icons, and UI elements on a dark background.    

Advantages of Dark Mode

  • If you are working in a low-light environment, it is more comfortable to read white text on a black background. With Dark Mode, you no longer have to strain your eyesight with too much bright white light. 
  • Dark Mode is the best bet when you have someone sleeping next to you while you are working. 
  • For people suffering from photophobia, bright light can aggravate the condition of migraine. Dark Mode is great for such people. 
  • Dark Mode follows all the accessibility principles.
  • While it is easier on the eyes, it is also good for the battery life of the devices. 

That brings us to the next section: How has Dark Mode influenced the email industry?

Dark mode in Email

With dark mode, the background color will automatically change from the original design and get reversed to a dark background. In other words, the actual color values could be different according to the device, email clients, and version of the Operating System. 

For plain text emails, Dark Mode does not have any major implications. However, if you are using HTML emails, it can lead to variation in the renderability.

Here’s an example of an email that does not render well in dark mode and hampers the subscriber’s experience. 

Few of the developers at Email Uplers, who work in full time engagement (FTE) with a few of fortune 500 clients and other companies share some insights into what challenges they as individual developers have faced and the above brands might have faced while dealing with Dark Mode.

1. A client had provided a single image that was not layered. It is critical to cut and create PNG images especially when we need to cut a logo. In such a scenario, our design team will create and use PNG images in HTML. 

2. If the client is looking for CTA flexibility, we have to code CTA curves with CSS. In that case, Dark Mode issue is resolved but doesn’t display a curve in Outlook Desktop. 

3. Flashy images in emails can lead to various challenges that can be resolved by adjusting media query for Dark Mode.  

How to Optimize Dark mode in Email?

These are some of the best ways to tackle Dark Mode issues while creating an email:

1. Enable Dark Mode in email client

2. Add Dark Mode styles

a. @media (prefers-color-scheme: dark)

b. [data-ogsc] prefix

3. Apply it to your HTML

4. Optimize your logos and images

a. Logo 

Add a stroke around the design so that it stands out on the dark background.  

b. Icons

For icons, you must use the same principle that is used for logos. 

c. CTA

Here’s an image to illustrate how to design a CTA with curved angles.

**Make sure every image needs to be transparent, and in PNG format. 

Exploring Dark Mode Compatibility 

Barring certain older email clients and Operating Systems, Dark Mode is supported in all the latest email clients and devices. However, each OS provides Accessibility and Display setting options especially for other people who may have a visual impairment that make it easier to read bright text on a dark background.  

Take a look at the below table for more clarity on dark mode compatibility. 

Test your emails for rendering (ALWAYS!)

The world of email clients is evolving at a great pace. To make sure that your emails render well and impart a flawless experience to your subscribers, you must test your emails for compatibility across all devices and email clients. While you can use Litmus and Email on Acid, it is also advisable to test the emails on real devices.

That pretty much sums up dark mode in emails. If you need any help with executing emails compatible in dark mode, Email Uplers would love to help.
