Most of the emails sent around the world nowadays are spam, in other words – unrequested messages with various offers or with hyperlinks to malware. Not only are such emails irritating, but they also pose a risk to your personal computer, not to mention that you may get duped. That’s why, many email service providers resort to spam filters, which are apps that keep track of all inbound email messages and filter the unwanted ones on the basis of their content – what words an email contains and how often they’re mentioned, what website a specific link points to, what outgoing server the message comes from, and so on. Some web hosting providers also rely on the databases of spam-monitoring organizations dedicated to the provision of the most up-to-date information about unrequested messages, to make sure that their clients won’t receive any email in their inbox that’s not supposed to be there.
