It may be helpful to visualize how your email looks across various screen sizes. In the upper right corner of the Preview, click the Layout button and then select Card. You'll have the option to create separate previews with common device screen sizes. Note that Live "device" previews are actually just previews rendered at the specified screen dimensions. For real device previews, see Inbox Previews. You can easily differentiate between Live and Inbox previews by the colored label on each option.
Silent video of the full Parcel window. A sample email is displayed in the Editor and the Preview. The user clicks the "Previews" button above the preview window, which replaces the window with a new screen. This new panel has a search bar, filter button, and a long checklist of different devices divided into categories ("Mobile", "Desktop", "Web", "Tablet"). Next to each checkbox entry is a colored box reading either "Live", with a red background, or "Inbox", with a blue background. The user clicks the filter button, revealing a menu with options to include "Inbox Previews" and/or "Live Previews", the "Latest Versions" or "All versions" of the operating systems, browsers, and color scheme. The user exits this menu without changing any options, and then clicks the "Select all" checkbox for the mobile devices, which selects 20 devices. Some of the devices selected are labeled "Live" and others are labeled "Inbox". The user clicks the "Continue" button, and the device selection screen is replaced with a new screen. This new window has square-cropped previews of the email for each selected device. The "Live" previews show a preview of the email, while the "Inbox" previews are still blank. The user clicks the "Refresh" button at the top right of one Inbox preview. The blank square is replaced with a loading symbol and then again replaced with a square cropped screenshot of the email in Gmail. The user clicks on the Gmail preview, which is then opened full screen within the Preview window. After reviewing the preview, the user clicks the "Minimize" button at the top and is returned to the previous view with multiple previews.

All of the Live previews will update automatically whenever changes are made to the email. You can view previews for HTML, Text, or AMP by switching to that tab - the previews will update to match. Inbox Previews only display the HTML/MJML part.

You can apply Visual Impairments, Image Blocking, and Dark Mode to each separate preview individually (with the buttons at it's border) or to all previews at once (with the buttons above the full preview window). Screenshots can similarly be taken of individual previews or all of the previews at once. If you take a screenshot of all of the previews, you'll get a zip file containing each image.
