Making Superscript Tags Work In Email

Often in marketing emails we need to apply caveats to pieces of copy, linking to terms and conditions below or on a separate page1. However, just using the <sup> tag to superscript text can cause issues with line height in certain email clients and browsers.

The following style, when applied to <sup> tags, will fix these issues.

<sup style=”line-height:1; vertical-align:baseline;_vertical-align: bottom;position: relative;bottom: 1ex;font-size:11px !important;”>2</sup>
