[Now Fixed] Email Issue: © Copyright symbol breaking in Hotmail

Update – 26 April 2012

As mentioned by Brian Thies in the comments below, Hotmail have now released an update to their platform that fixes this bug, therefore designers don’t need to take any action to update their code. We’ve run a few tests through Hotmail and the symbols are now being displayed as normal.

We’ve noticed a peculiar rendering issue that’s just appeared in Hotmail – the © ASCII code used to insert a copyright symbol loses all formatting. We’ve run some tests in various live browsers, and the issue seems to appear in IE, Firefox and Chrome/Safari. It appears that the symbols are actually being replaced by Hotmail’s own emoji images, for example:  .

HTML Email Issue: loss of backgrounds in Hotmail (includes fix)

Various email clients have different quirks and html challenges – in our HTML email coding section we document these and detail any workarounds if available.

Email Client Affected:

This issue affects the new version of Hotmail.


Hotmail have introduced a code in their rendering engine that effectively removes the background image or colour properties from ‘wrapper’ full width tables. Full width tables are commonly used in html emails to implement background formatting and to center the main email, and are specified as 100% wide.

Effectively the new Hotmail code forces the maximum width of the email to be widest part of the email defined in pixels, which may be either an image or a table.


Whilst the width of the wrapping table could be forced out to a certain width (eg. 1000px), this would cause other rendering issues in other platforms (and it would be pretty impractical). Instead, a small CSS code snippet can be used to force the width back out to 100% – simply add this code at the top of the email HTML code:

<STYLE type=”text/css”>
{ width: 100%;}
{width: 100%;}
