Previewing emails

The controls above the email preview let you check how your email may look at different screen sizes and in different colour modes.

Previewing desktop and mobile layouts

Open the email in the editor, then select one of the device buttons above the preview:

• Desktop shows the email in a wider preview.
• Mobile narrows the preview to a mobile-sized screen.

Switch between both views to check text wrapping, spacing, image sizes, and whether buttons and links are easy to use.

Previewing dark mode

To check your email in dark mode:

1. Above the email preview, select the dark mode button beside the desktop and mobile buttons.
2. Choose a preview mode:
   • Light shows the email with dark mode off.
   • Dark applies the email’s own dark mode styles. This approximates clients that respect those styles, such as Apple Mail and Outlook on the web.
   • Forced dark approximates clients that recolour the email themselves, such as Gmail and other Android apps.

Switch between the modes to check that text remains readable and that images, backgrounds, buttons, and links are clear.

Email clients and devices can render emails differently, so these previews are approximations. Before sending a campaign, send test emails and check them in the email clients your audience uses.
