Canvas

The canvas shows the email three times, side by side:
  • Desktop: where you click to edit.
  • Mobile: the email at phone width. Click it to make phone-only changes.
  • Dark mode preview: how the email looks in an inbox’s dark mode.
The toolbar at the bottom has:
  • Select (V), Hand tool (H, or hold Space) and Comment (C).
  • The zoom menu: Zoom in, Zoom out, Zoom to 50%, Zoom to 100%, Fit all and Dark mode previews on or off.
  • Show with images blocked: how the email looks before images load.
  • The email’s size, so you can keep it under Gmail’s limit.

Right panel

Email settings

Click an empty part of the canvas, then More settings. Or open the menu at the top left and choose Email settings.
  • Sending: Where it’s going (your email platform, which sets the merge tag and condition syntax), Language and Text direction.
  • Link tracking: UTM tags added to links.
  • Brand styles: the brand styles this email uses.

Version history

Open the menu at the top left and choose Version history.
  • The Builder keeps a restore point about every five minutes while you edit.
  • Click Name the current version to keep a version you want to find again. Filter by All versions or Named.
  • Pick a version and click Restore this version. Restoring makes a new version and clears the email’s approval.
