Problems with image alignment in ENewsletter PLugin

When I create an email with this plugin everything looks fine in the wordpress preview (images are aligned correctly). However when opened in Outlook or Gmail, the images are not aligned - text is in direct line with the images. CSS is below. Ive changed themes, tried new newsletters with different images, no luck.

<style type="text/css">

            a:link, a, a:visited{color:#669966;}

            a:hover { text-decoration: none !important; color:#669966;}

            h1, h2, h3, h4, h5, h6{font-family:"open sans condensed"; padding: 0px 0px 10px 0px;margin:0px; color:#669966;}

			.alignleft { display: inline; float: left; margin-right: 1.625em; }

			.alignright { display: inline; float: right; margin-left: 1.625em; }

			.aligncenter { clear: both; display: block;	margin-left: auto; margin-right: auto; }

			img.alignleft, img.alignright, img.aligncenter { margin-bottom: 1.625em; }

        </style>
