SenderOK is email management software that prioritizes incoming emails, labels them as VIP, Important and Routine and places their virtual copies to the corresponding folders.SenderOK uses its proprietary algorithm to define senders importance for a particular user. It takes into account both user behavior and objective global factors, for instance, if many people classify email from a certain sender VIP.SenderOK lets its users know about emails from important senders by visual (icon in the system tray) and sound notifications. SenderOK inserts a photo business card into the email header pane, and places all messages and attachments from a sender onto a special window in the message preview pane.SenderOK helps its users to spend less time on email handling because it focuses on good email only. Bacn and spam do not enter SenderOK virtual folders, so its users spend no time on their preview and removal.In addition, SenderOK gives its users possibility to exchange virtual business cards with their email contacts. SenderOK users can keep their details always up to date and inform other people about their changes, and also get timely updates on other SenderOK users changes. This service is available both as a part of the software package and as an individual Web service.
