Often content in an email is organised in multiple columns. When viewed on a mobile device, those columns can become quite narrow and lead to a sub-optimal reading experience. In order to guarantee a better experience while reading emails on mobile devices, EmailOut’s Drag & Drop Editor generates HTML code that makes columns stack vertically. This way content is reorganised in a way that makes zooming unnecessary and is easy to scroll with a finger.

Desktop vs mobile preview

Vertical stacking is supported by the most popular mobile email clients. In some cases, the desktop version will be displayed. That happens when a client lacks support for standard CSS. For an overview of email client compatibility, please see the email client support section. 

One size doesn't fit all

Although it normally helps, there are cases in which vertical stacking of columns may not lead to an optimal result.

A common scenario is using a row to display a navigation bar with text links or icons. In that scenario, as shown below, a vertical layout could create excessive empty space, hiding important elements of the message or giving too much visibility at the top of the email to content that is not supposed to be that prominent.

Changing the default behaviour

With the introduction of the Do not stack on mobile row setting, users of the Drag & Drop editor can now decide when to override the default behaviour and prevent columns from stacking vertically on mobile devices.

An example with illustrations.

The option is available in the right pane as a row property, off by default.

"Do not stack" and email design best practices

Email design best practices suggest a careful use of this display setting, as keeping a user-friendly vertical layout on mobile makes sense in most cases. As always, it is up to you and your creativity when and how to use this option.

Have fun! 🙂
