Less Clutter Reduce Inbox Anxiety Increase Productivity

Cloudmark Content CategoriesTM moves perceived clutter out of the Inbox allowing users to concentrate on important person to person (P2P) messages.


Over time email users provide their email addresses to organizations who subscribe them to various lists to receive updates, promotions and mailing list messages. While the majority of mailings generated by these organizations are legitimate, user perception is that they’re spam because they are unwanted. By tagging of specific classes of messages and enabling the messaging platform to automatically move them out of the user inbox view and placing them in separate folders or tabs, the user experience improves and user perception of spam detection is increased.

Flexible Inbox Management

Cloudmark Content Categories enable quick and easy implementation of Priority Inbox features within any webmail application. Specific categories of messages can be shown in separate folders or tabs, depending on the end user’s preference. Content Categories help users to sort through the ever-increasing volume of email messages received that are of interest but do not require immediate attention.
