One of the most frustrating things about spam is that it needlessly interrupts you throughout the day.

Qurb solves this problem by only alerting you when mail is received from an approved sender. By eliminating interruptions from spam, Qurb improves your productivity.

Qurb provides an optional sender confirmation feature (also known as challenge/response system) that can completely eliminate the need to review quarantined messages. When this feature is enabled, Qurb automatically sends your personalized confirmation message to unknown senders. If they simply reply to the message, their original messages will automatically be moved to your Inbox and they will be added to the white list of approved senders. Only messages sent by real people will get through to your Inbox.

• Completely eliminates the need to review quarantined messages
• Allows human senders to reach you via e-mail, even if they were previously unknown to you
• Customizable confirmation message enables you to personalize the sender confirmation request for the best possible results
