Previewing an email allows you to see what your contacts will receive. If you're using Liquid or any other dynamic content, such as Cart Contents, previewing is the best way to ensure that your email will look as desired.
To preview a broadcast, you can click on "Preview" on the broadcast screen. In the preview window, you can toggle between Desktop and Mobile views.
You can also preview your broadcast directly from the email editor. When editing a broadcast, click on "Actions" at the top right, then on "Preview".
ℹ️ Note: this will be available when we launch our new editor for automations, within the next few days. Stay tuned!
To preview automations, you can use the same "Actions" > "Preview" button in the email editor as for broadcasts.
