How dark mode impacts the look of your email

Article: 000045165
Updated: June 17, 2026

Your email may look different to recipients who have dark mode enabled

Dark mode is a reversed color scheme that employs light-colored text, icons, and other elements on a dark background. It can be enabled on your device — and in some cases within an email client — and affects how emails appear, depending on the client (such as Outlook and Gmail), on both desktop and mobile devices.

 

Enabling light or dark mode on different devices

Contacts enable light or dark mode on their Android phone, iOS device, Mac, or PC. 

 

On iOS: 

  1. Go to Settings
  2. Go to Display & Brightness. 
  3. Tap Light or Dark mode. 

 

On Android:

  1. Go to Settings
  2. Go to Display & Brightness. 
  3. Tap Light or Dark mode.

  1. Go to the System Settings app. 
  2. Click Appearance in the sidebar.
  3. Scroll down and select Auto, Light, or Dark.

 

On PC: 

  1. Right-click any empty space on your desktop.
  2. Select Personalize.
  3. Select Colors
  4. Change "Choose your mode" (or "Choose your color") to Light or Dark.

How dark mode impacts emails

When dark mode is turned on, it can impact the look of an email in one of three ways, depending on the email client and whether the email is viewed on a desktop or on a mobile device:

  • No color change - background and text will not be impacted 
  • Partial color invert - light background and text becomes dark
  • Full color invert - light background and text becomes dark and dark background and text becomes light

Because it's a setting that recipients turn on or off themselves, you can't control the impact it may have on the look of your emails. Ultimately, if a recipient chooses to enable dark mode, your emails will appear as the recipient prefers.

Note: Many third-party factors are involved in displaying content in dark mode. We are unable to force the receiving program to display the email with a specific color scheme or to prevent dark mode from being applied. The receiving program determines how to display the email.
