From the developer:
HTML Email Signature - Mail is an application that allows customized creation of e-mail signatures from HTML. You simply add your HTML, and your signature is created. A button to preview the HTML is also available. However, a valid HTML must be provided. Since this is not a design utility, issues with formatting and/or appearance of the final signature are directly tied to the HTML code.
