How It Works
Dark mode inverts light backgrounds to dark and dark text to light. Emails with pure white backgrounds may look jarring, and images with transparent backgrounds may disappear. Test your colours to ensure readability in both modes.
Designing Emails for Dark Mode
Dark mode adoption varies by email client, but ignoring it can make your email unreadable or visually broken for a meaningful portion of your audience.
Use semantic colours, avoid pure black or pure white, and add solid backgrounds to logos and buttons so they remain visible when clients invert colours.
