SBook is a uniquely flexible, intelligent contact management tool for business professionals. Its fast, smart searching allows you to structure and maintain your contact information in any way you like. SBook automatically recognizes phone numbers, postal addresses, and e-mail addresses. It knows the difference between fax and voice numbers and can dial either with a single click of the mouse. Once you've built your contact database, SBook can print your list onto a wide range of standard mailing labels or it can print out envelopes complete with postal barcodes for faster delivery. SBook even lets you log each phone call, fax, and letter you send.
