What is the difference between text and HTML versions of email?
A plain text email looks like something written in a basic text editor, containing no colors, graphics, or design elements. HTML emails allow you to place graphics and text with different font treatments. All HTML emails can be tracked using a one pixel high invisible image and most email programs give users the option to display HTML or text. Informz has something called “content-type alternative” to send out HTML emails. It determines whether a recipient can view the HTML or text version depending on what email software, (and version #), they are using and how their mail servers are configured. It basically bundles both the HTML version and the text version together in one email and based on the subscribers’ email software, it will display the most readable version to them, with HTML taking precedence.
