Advantages of email -or electronic mail
• Emails can be sent in bulk
One email message can be sent to multiple recipients almost at the cost of a single email. When compared to conventional postal service this is indeed a huge saving.
• Almost instantaneous
Email messages are transferred instantly - well almost. They move as fast as current in copperwires or light in optical cables, which is pretty darn quick. When you send an email is leaves your computer and arrives at the recipient's inbox immediately. You can potentially have a conversation with a person over email - hence, the conversation view in Gmail.

If you have a 24 hour internet such as a through cable / broadband connection, the cost of sending an email is zero or very very small. For dialup users, the maximum cost of sending an email will be that of a phone call or a few (depending on the size of the message and the files attached).
• Delivery is almost guaranteed
The delivery of email messages in almost guaranteed. Why do I say "almost"? Because sometimes for reasons that are beyond the scope of this article, email can get lost in cyberspace but this is very rare.
• Email is accessible
This is one of the greatest advantages of using email - its accessible anywhere, anytime and through a multitude of devices - computers, laptops, palmtops and even cell phones.
One can check email from any location as long as an active internet connection is available. Also email can be sent from any place with the same requirement of an active net connection.

Most email programs (or email clients) have built in spell check dictionaries - so you have no excuse of sending badly written messages. Spell checkers are also found in online email services such as Hotmail and Yahoo.
Several, if not all, steps in the emailing process can be automated. A good example is sending birthday greetings to people. An email program checks the birthday and the name of the recipient from a list. A message (from a template) is then formulated and sent on the specified date.
• Notification of new arrivals
Email programs or devices can also be set up so you get a notification through sound or a flash of light when new messages arrive at your inbox. Can be formal as well as informal Email messages do not signify informality. Just because email is easy to compose and send does not mean it cannot be used in formal and official correspondences.
