Background Images in Emails: The Why, How, and Wow of it!

Background Images in Emails

[This blog was originally posted on

Background images are like icing on the cake in marketing emails. You have worked hard on the content of the email; now if you back it with a pixel-perfect email background image that is closely related to either your brand or the content of your email, you are adding significantly to your chances of getting better conversion rates.

Why Email Background Images?

Our brain can process visuals at an incredible speed of 0.013 seconds. Another research reveals that 92.6% of people say that the visual dimension is the primary factor affecting their purchase decision. Thus, brands often rely on product images and graphics to generate interest in marketing emails; and adding background images is one such powerful tool used by them. Simply put, mail background images accentuate the visual appeal of your email and incentivize your readers to interact with the content. 

This design technique is applied well in the world of the web but, unfortunately, as far as emails are concerned, marketers are still reluctant to use this really appealing marketing tool. Why?
The main issue with adding a background image in the email is that it is not supported across all email clients (image blocking). For instance, rendering an Outlook background image is a task and a half. So, if you wish to create that wow factor with background images in an email template, you need to know which ESPs will support your images and which will expect you to go the extra mile to make sure your design appears just the way you want it to. That means acquainting yourself with the rendering rules that are associated with each client. An Outlook background image, for example, displays correctly only when there’s one background for the entire email. If you attempt to have different backgrounds for different email elements, the bugs start announcing themselves.

Email image blocking is a result of many email providers’ default settings or personal preferences provided by them. Blocking might hamper your marketing campaign and even fail to make an impact on prospects; in some extreme cases you might just end up casting an unfavorable impression on your readers.
An improper text-to-image ratio (which is not 80:20) can be catastrophic for your email campaign if the email client blocks your images. Best Practices to follow for Perfect Text-to-Image ratio in emails >>

So, let’s focus on a tool that will help your email background template to render across all email providers – well almost all.

How To Add Background Images – A Bulletproof Tool

The prime culprit seems to be Outlook 07/10/13, which does not support either table background email images or background-image styles. Campaign Monitor’s bulletproof background image technique can be a good solution to this problem. Make sure you check whether your ESPs support VML (Vector Markup Language) coding if you have a single whole background image for your email. But just in case you are repeating the email template background image, you can apply that in the body and top table tag with repeat property and it will render in Outlook 7, 10, 13 even without VML code.

Here, you get an option of applying email template colorful backgrounds to the entire email as well as table cells; and you can generate a code for both scenarios.

The only issue that might arise is the size of the image. In case Outlook 2000 and above considers your image to be too big (size or dimensions), it might crash. So before you go for an HTML email background image, it is very important that you check whether your images are sized correctly, Also, test your email in a live copy of Outlook.

To be on the safer side, it’s always good to have an ALT text for your images. Include the dimensions of your image – the width and height of your email image give your ALT text a display container when images are disabled. If you do not mention the dimensions, some email clients collapse that area, and off goes your ALT text too.
Another option that can be considered in case the image doesn’t open in emails is to set a background color as a fallback. This will ensure that, even if the background image doesn’t show, the content of your email is readable against the fallback color.
