Without adequate security and suitable control over the messages your employees send and receive, rather than being an enabler email can become a business disabler. Uncontrolled email presents a threat to any business – from the introduction of a destructive virus damaging your internal network (not to mention your reputation with customers and business partners if you pass it on), down to the time individual employees spend deleting spam from their inboxes – it all presents a potential high cost to the business in terms of productivity and reputation. Publishing an email address on your corporate website, social networking site or other public area can leave the email account open to being flooded with spam. Official reports vary in their definitions, but all point to the fact that around 90% of email traffic sent across the internet is spam, and 95% of known viruses are spread by spam email – facing statistics like that businesses need to ensure they have appropriate measures in place before they are compromised or their email becomes unusable.
