The use of e-mail requires access to the Internet. The use of the word e-mail has been widespread since people began to use e-mail to send a message or document. In several situations, people refer a message they send to and receive by the e-mail system as an e-mail. It is also acceptable to use the word e-mail as a verb. For example, Can you e-mail me the schedule? To start using e-mail, we need to have our own e-mail addresses such as boonklee@yahoo.com, Noppadol@ppp.co.th and kraiwans@bristol.ac.uk.
