For example, you could repeat a pattern, like the Lego pattern shown in the screenshot below:

Or you could use a single background image that covers the whole width of the message (e.g. in the heading of the email). This too is easy to do with the new Row Background Image feature in the Knak advanced email editor.

Modifying the email message from above, the same message could now adopt a different design and look like this:

Where to find it?

When you select a row in the design pane, you'll see that the Row Properties panel now includes a new Row background image section:

Let's look at the settings included in this new section.

Row background image settings explained

Selecting the image

Once you click to enable this feature, you can upload the image that will be used as background via the file manager by using the Change image button. Alternatively, you can copy and paste the image URL into the URL box if you wish to use an image hosted elsewhere.

Full width, Repeat, and Center

These three settings - Full width, Repeat, and Center - are important for aligning and finding the best fit for your background image or pattern within your message. Let's see how they can be used.

Full width

When selected, the image is used as a background for the entire width of the row. For example, here is a Lego brick pattern repeated across an entire row (click on the image to see a larger version where you can see the background pattern).

When not selected, the background image is applied only to the Content area. The width of the Content area is set in the Body tab of the Property panel.

Here is the same pattern applied only to the content area.

Repeat

When selected, the image is repeated. This works well with symmetrical patterns. If you chose to repeat the coffee beans image, for instance, the message would now look like this:

Use "Full width" and "Repeat" together if you want to repeat a pattern across the width of the row. If the row is higher than the height of the image, the pattern will be repeated vertically too.

Center

When selected the image is centered. If "Repeat" is also active, the image is centered and then repeated to the left and to the right. If you "Repeat" without centering, the image is positioned in the top-left corner of the row, and then repeated to the right.

All three settings can be enabled and disabled independently of each other. Try uploading a small image and play around with them to understand how the positioning of the image is affected.

Email client compatibility

The Knak advanced email editor looks to ensure that background images are rendered on most email clients. However please note that there are some email clients where background images will not show:

  • Outlook 2011, 2013 and 2016 on Windows
  • Lotus Notes 7
  • Xfinity / Comcast email client

For those email clients - and for best results when images are blocked - make sure that you set a background color for the row that works well in the absence of the background image.

Changes to image resizing

In order to make the system more compatible with the row background image feature, a few other changes were introduced.

  1. The allowed max-width size limit for images was increased to allow for wide images
  2. To compensate the file size increase, all the images are automatically optimized without quality loss
  3. Only the biggest images are resized during the upload.
