Most people read email on a phone. The builder’s phone view lets you change text size, spacing and alignment for phones only, hide a block on phones or on desktop, and fix the problems phone readers hit most often.

Switch to the phone view

Click the phone icon at the top of the builder. The canvas narrows to 375 pixels, the width of a typical phone. In the phone view, these changes apply to phones only:
  • font size
  • padding
  • text alignment
Every other change applies everywhere: the words, links, images and colours. Switch back to the desktop icon and the desktop design is as you left it. A block with phone changes shows them under Inspect → On phones → Phone overrides. Click Reset next to a change to remove it, so the phone uses the desktop value again.

Show a block on one kind of device

Select the block and open Inspect → On phones. Under Show on, pick:
  • All devices: the default.
  • Desktop only: phones do not show the block. Use it for a wide table or a long product grid that reads badly on a small screen.
  • Phones only: only phones show the block. Use it for a short “Tap to call” button or a smaller image.
The canvas dims a block the current view does not show, and labels it Desktop only or Phones only. You can still select and edit it. Some mail apps ignore phone styles, such as Outlook on Windows and Gmail used with a non-Google address. They show Desktop only blocks and never show Phones only blocks. Keep anything a reader must see in a block shown on all devices.

Full-width buttons and images

For a Button or an Image, tick Full-width button on phones or Full-width image on phones. The button then fills the screen width and gets a taller tap area. The image fills the width, edge to edge.

Phone check

In the phone view, a strip above the canvas lists what a phone reader would struggle with: Click a line to select the block, Fix to fix one, or Fix all. Blocks set to Desktop only are not checked.

Where it applies

Phone settings are part of the email itself, so every campaign, automation email, transactional email, test send and hosted “view in browser” copy carries them. The Preview tab and the split desktop/phone preview show each device its own version. AMP emails do not use phone settings.
