What is HTML Email?
An HTML email is an email sent in a hypertext markup language
(HTML) format that allows displayed images as well as a text message. Information may be shown in web page form that is visually more appealing and easier to navigate and scan than a plain text email. Rates for email opens, forwards, and clickthroughs are able to be more easily tracked. Products and topic interests can more readily be measured. However, HTML files and a large number of images cannot just be attached to a message and sent, nor can code just be pasted into the email application.
