In the fast-paced, competitive world of information technology, a company's existence is highly dependent on the speed and reliability of its communication. Along with mobile phones and the Internet, there comes an ever increasing demand to have access to the electronic e-mail service anywhere, at any time. As compared to other messaging media like SMS messages and faxes, e-mail services are quite flexible and cost-effective, while having fewer message length limitations.
Due to its advantages, all companies, from startups to large corporations, employ such services, often at a small scale. To circumvent many of the costs and complications of hosting a dedicated e-mail system within the company, they opt to outsource this service. This approach is sufficient on the short-run. However, any growing company can benefit from the dedicated services of a mail server, learning to gradually rely on the features they provide.
