Frames were very popular in the late 1990’s because they gave flexibility and structure to websites. It allowed web designers to combine several pages into one. The main problem was that the individual elements of the frameset indexed in the search engines, whilst the frameset did not. The increased use of CSS to layout pages has rendered this method virtually obsolete.

HyperText Markup Language (or HTML) is the proprietary mark up or coding language for Web pages. HTML is written in the form of tags and can be read by all Internet browsers.

An HTML Email is created and formatted using Hypertext Markup Language. This allows the inclusion of images and specific fonts and colour schemes. An HTML email will often follow a corporate look so the recipient can make a visual link between the online and offline marketing activity of the company or person who sent it.
