HTML/RTF formatted email - what is it?
All email software support raw text format, which is just text without any special fonts nor font colors or images.
RTF/HTML formatted email can contain both text written with special fonts, images and advanced formatting for example such as indent. These emails contain a code which the email software interprets. The code is the same as the code used to create web pages, named HTML.
In order to be able to view RTF/HTML formatted email
you need an email client that supports it. Examples are Microsoft's free email
client Outlook Express
or Qualcomm's Eudora.
In case your email client doesn's support RTF/HTML formatted email the message is sometimes shown as an attachment. If this is the case you just need to open it in your webbrowser to view it.
