An indication of the order in which you will set out your argument, the related terms and theories to which you will be referring, an idea of how you will support that argument with evidence, and a final sentence that leads the reader smoothly into the main body of your essay.
Suppose a fee was charged for every email sent. Consider how this would change the behaviour of email users, and the likely impact on spam.
Email, or electronic mail, has transformed business and personal communication mainly because once an internet connection has been established there are no distance or cost implications. According to Mashable (2013), approximately 144.8 billion emails were sent in 2012. Email’s advertising potential was quickly identified, with the result that unsolicited advertising emails, ‘spam’, now account for 80% of email traffic (Goodman et al, 2007). Since spam both clogs up inboxes and slows down the networks, charging a fee – perhaps a penny – for each email sent is often cited as a solution, curtailing even solicited email traffic. In evaluating the effect of a fee on email users’ behaviour and assessing the likely impact on spam, this essay will focus on three key themes: freedom, practicality and likelihood of success.
