Setting a background color for an HTML email message

Wrapper table

There are different ways to set the background color for an HTML message. One is to create a wrapper table with that background color, like this:

<table width="100%" cellpadding="0" cellspacing="0" border="0" bgcolor="#efefef" style="background-color: #efefef;">
	<tr>
		<td bgcolor="#efefef" style="background-color: #efefef;">
		... your email content here ...
		</td>
	</tr>
</table>

... where the color here is set to a light gray (#efefef). Note that:

Defining the color both via the bgcolor property and via a style increases the likelyhood of the email client being compatible with the code.
The same is true for setting the color at the cell level as well (<TD> tag)

This method has been used extensively as it gets around the problem of email clients ignoring the <HEAD> and <BODY> tags (e.g. Yahoo! Mail). There are however a couple of issues with this method:

It leaves a small, white border around the message in some email clients
It can create a problem in Outlook (2007, 2010) when the message height exceeds 23 inches, if you set the table width to 100%. If you don't, then there might be some white space at the botton of the message.

Style in BODY tag

As email clients are getting better at handling the <HEAD> and <BODY> tags, you can also set the background color by placing a bit of HTML code inside the BODY tag of the message.

In MailUp, you can add code to the BODY tag by following these steps:

Edit the message
On the editing page, click on the Advanced button to open a window that gives you access to advanced features
Turn on Customize HTML headings
Edit the BODY tag as follows (in this example the background color is a light grey).

<body>

... becomes:

<body bgcolor="#efefef" style="background-color: #efefef;">

By using both the bgcolor and a style, we take care of a wider array of email clients, increasing the likelyhood that the background will be rendered correctly.

This method of setting the background color was previously not recommended mostly because Gmail used to ignore the BODY tag. This is however no longer the case, and the above code works just fine in Gmail.

As of the time of this writing (Feb 2014), unfortunately Yahoo! Mail still does not support this method of setting the background color (it still ignores the BODY tag).

This method gets rid of the two issues mentioned above for the wrapper table, but is still affected by lack of support in some email clients.

Combining both methods

For best results, the safest way to go is to use both of these methods at the same time. They do not conflict. So...

Add background styling to the BODY tag
Use a wrapper table to add support for email clients that ignore the BODY tag
