Techniques for synchronizing personal contact information with or from different sources are disclosed. Through a website (i.e., a server or system), all fractional personal contact information is consolidated, synchronized, processed or updated. In return, any of the resources may be synchronized to get a copy of the latest version of the contact information. When contacts in a list by a registered user are also registered with the server, any of the contacts may update their respective contact information that can be timely reflected in the list. As a result, the registered user always has a latest version of the contact information for some or all of his/her contacts without even knowing some has already been changed or updated. Based on the contact information, other features including proof delivery of emails, recycling of deleted contacts, a 'black' list, contact relationship levels and anonymous email, short messaging and calls are provided.
