Description




FIELD OF THE INVENTION




This invention relates generally to messaging systems. More particularly, in the preferred embodiments, this invention is directed to techniques allowing a recipient, receiving messages from a plurality of different messaging systems operated by respective senders desiring to communicate with the recipient, to control various aspects of the messages generated by the senders and intended for the recipient.




BACKGROUND OF THE INVENTION




Traditionally, recipients (individuals, businesses and households) have had little opportunity to influence the mail that is sent to them. Merely having a post office address has served as an open invitation to mailers (one type of message senders) wishing to communicate with the recipient. Historically, recipients have been limited in their ability to control any aspects of the mail.




Many factors place increased demands on the effectiveness of messages. First, the costs of generating and delivering messages is always increasing. Second, senders must compete for the recipient's attention due to the large number of messages that are typically received. Third, recipients need timely and easy access to their messages so that they are able to retrieve and discern them efficiently. Numerous other factors exist.




Generally, various postal authorities around the world provided some narrow ability for a recipient to control the mail. One service is mail forwarding (holiday, temporary move, secondary address, etc.) where the mail is redirected from an original address specified by the sender to another address specified by the recipient. This service may be utilized when the recipient moves. Although this service generally works well, it suffers from certain drawbacks and disadvantages. As an example, delays are typically involved in redirecting the mail. Furthermore, the sender is typically unaware of the new address and may continue to send subsequent mail to the old address. Address correction databases that contain updated information about the recipient's address are only updated periodically and must be accessed by the sender to obtain that new information. This delay has potential negative consequences for both the sender and the recipient. As another example, delivery costs for the postal authority are increased because the mail is often routed to the old address before being forwarded to the new address. Therefore, due to all of the above, the sender and the recipient suffer a loss in quality of service while cost for the postal authority increase.




In addition to or as an alternative to notifying the postal authority and described above, the recipient who has moved may attempt to provide various senders with the new address. However, this is time consuming and generally not very effective since it may only pertain to physical mail.




Another type of service is mail holding where the mail is held by the postal authority and not delivered to the recipient. This service may be utilized when the recipient is away from home for a period of time. Although this service generally works well, it suffers from certain drawbacks and disadvantages. As an example, mail tends to collect at the postal authority facilities and this increases storage and handling costs for the postal authority. Furthermore, the sender is typically unaware of the hold that has been placed on delivery and may continue to send subsequent mail believing that the recipient is receiving mail. This compounds the storage problem for the postal authority and the timeliness issue for the sender and the recipient.




Therefore, due to all of the above, the sender and the recipient suffer a loss in quality of service while costs for the postal authority are generally increased. As a result, there is a need for improved recipient control over various parameters associated with messages, in particular mail, intended for a recipient.




SUMMARY OF THE INVENTION




The present invention provides a system and methods for improving the collection and dissemination of recipient preferences for messages. Generally, this is accomplished by collecting recipient preference data and making it available to a plurality of discrete messaging systems for use in preparing messages intended for a selected recipient.




In accordance with the present invention, there is provided a system including a plurality of messaging systems, a data center and a control system.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring to

FIG. 1

, an example of a system


100


for collecting message preference data from recipients


180


and providing those preferences to senders of messages, in which the present invention may be incorporated, is shown. The information system includes a data center


110


in communication over any suitable communication network


102


(LAN, WAN, telephone line, Internet, etc.) with a plurality of remotely located (geographically dispersed) messaging systems


150


and a plurality of remotely located recipients


180


. The messaging systems


150


may include any device that is utilized by a sender (not shown) to produce a message (not shown) intended for a recipient


180


(described in greater detail below). Examples of messaging systems are: a traditional postage meter


152


, such as the Personal Post™ meter; an open system postage meter


154


, such as the ClickStamp™ online postage system employing a personal computer


154




a


and a dot matrix (laser, ink jet, thermal transfer, etc.) printer


154




b


; and an inserter


156


, such as the 8 Series™ inserting system; all available from Pitney Bowes of Stamford, Conn. Still other examples of messaging systems are shipping and logistics systems (not shown), addressing systems, such as the AddressRight™ system available from Pitney Bowes of Stamford, Conn., electronic mail (not shown) and the like. Because messaging systems are well know, there descriptions have been limited for the sake of brevity to only that which is necessary to provide suitable background for an understanding of the present invention.




Generally, it is anticipated that the messaging systems


150


would be located primarily in business offices and in private residences and used for a variety of purposes, including message creation, addressing, output generation and/or delivery. The data center


110


is maintained and operated by an administrative agency (not shown), such as the supplier of the messaging systems


150


, and may communicate with the messaging systems


150


in a variety of different ways. Those skilled in the art will recognize that not each messaging system


150


need utilize the same type of communication network


102


in contacting the data center


110


. Furthermore, depending on the needs of each messaging system


150


, the messaging systems


150


may or may not need full time access to the data center


110


to perform their respective tasks. The data center


110


may employ any suitable combination of computer hardware and software (control system) to facilitate the storage, access and processing of information and various communications that are required as described below.




In conventional fashion, the messaging systems


150


are used by their respective operators to perform one or more of the steps in the messaging process (creation, addressing, output generation, delivery, etc.). For example, the traditional postage meter


152


and the open system postage meter


154


may be used to apply a postal indicia (not shown) on an envelope (not shown) that contains a letter (not shown) for delivery to a recipient


180


. The postal indicia typically includes at least date and postage value data. The inserter


156


may be used to create, assemble, fold and/or insert a document (not shown) into an envelope (not shown) for subsequent delivery. Therefore, the inserter


156


may have information pertaining to the content of the envelope and the recipient


180


of the envelope. In analogous fashion, the other types of messaging systems


150


all have access to various data about the messages that they process. Those skilled in the art will appreciate that the types of data available are quite varied and ever increasing as newer more intelligent products are being introduced. Those skilled in the art will also appreciate that the messaging systems


150


each have their own suitable combination of computer hardware and software (control system) that operates to control the functioning of the messaging system


150


and communicate, as necessary, with the data center


110


.




The recipients


180


may be an individual


182


, a household


184


, a business


186


or any other entity or organization that receives messages. The recipients may communicate with the data center


110


in any conventional manner. As examples, the recipients


180


may communicate with an automated voice response system (not shown) over conventional telephone lines or via a web site located via a global communication network. Each of the recipients


180


establishes a recipient preference profile (see FIG.


2


and description below) that may be stored in the data center


110


in a recipient preference profiles database


192


. As necessary, the recipients


180


may access their profiles in order to make corrections and/or changes to any information in their respective preference profiles.




Referring to

FIG. 2

in view of

FIG. 1

, a template for a recipient preference profile


190


is shown. The recipient preference profile


190


is preferably stored in any suitable memory device (database server, memory farm, hard disk, etc.) and defines various parameters intended to control aspects of messages sent by the senders that are intended for the recipient. Those skilled in the art will recognize that the parameters defined below are mutually exclusive and may be employed in any combination. In conventional fashion, the recipient preference profiles


190


may be accessed by any suitable technique, such as an application software program executed by the data center


110


control system. The recipient preference profile


190


may include: a recipient identifier or ID data


190




a


; message format data


190




b


; delivery instruction data


190




c


; interest data


190




d


; no interest data


190




e


; primary address data


190




f


and secondary address data


190




g


. The recipient ID data


190




a


may be a name (individual, household or business) or any other suitably unique identifier (alphanumeric, etc.) and simply distinguishes the recipient


180


from other recipients


180


. The message format data


190




b


may indicate the recipient's preferred mode of communication (physical mail, electronic mail, facsimile transmission, voice mail, etc.), combination of modes of communication and/or priority for modes of communication in which to receive messages. The delivery instruction data


190




c


indicates if any optional delivery preferences, such as: hold messages, temporary reroute messages, etc.; are active. For example, a hold message instruction may be utilized by the recipient


180


when the recipient


180


is not available (vacation, business travel, etc.) to receive messages. As another example, the temporary reroute messages instruction may be utilized by the recipient


180


when the recipient


180


wished to have messages sent to an alternate address


190




g


(described below) during selected time periods, such as: vacation addresses and the like. The interest data


190




d


indicates if the recipient


180


has any desire to hear from particular types of senders. The no interest data


190




e


indicates if the recipient


180


has any desire to not hear from particular types of senders. The primary address data


190




f


represents the default address (postal delivery, electronic mail, phone number, etc.) to which messages should be sent. If the recipient


180


moves, then the primary address data


190




f


may be updated by the recipient


180


to reflect a new address. Analogously, the secondary address data


190




g


represents an alternate address to which messages should be sent if directed so by the delivery instruction data


190




c.






The interest data


190




d


and the no interest data


190




e


include indications of types of industry segments that the recipient may or may not, respectively, wish to hear from. These data


190




d


and


190




e


may be captured in any conventional manner. One system for available for use is the Standard Industry Code (SIC) system that assigns SIC numbers for a variety of well known industry segments. As examples, automobile rental companies would be assigned a SIC number in the range of 2100 to 2199, while automobile dealerships would be assigned a SIC number in the range of 2400-2499 and service stations would be assigned a SIC number in the range of 4000 to 4099. Still other SIC numbers exist for financial institutions, health care providers, legal service providers, professional associations, utility service providers, governmental agencies and a variety of other industry segments. Accordingly, SIC numbers corresponding to industries that the recipient


180


desires to hear from could be placed in the interest data


190




d


while SIC numbers corresponding to industries that the recipient


180


does not want to hear from could be placed in the no interest data


190




e.






With the structure of the information system


100


described as above, the operational characteristics will now be described with respect to how recipient preference profiles


190


are generated by the recipients and potentially used by the messaging systems


150


. Referring primarily to

FIG. 3

while referencing the structure of

FIGS. 1 and 2

, a schematic diagram of the information flow between the recipients


180


, the data center


110


and the messaging systems


150


that facilitates recipient influenced messaging in accordance with the present invention is shown.




Generally, the recipients


180


establish their respective recipient preference profiles


190


with the data center


110


in any conventional manner. These profiles


190


are then accessed by the messaging systems


150


at any time prior to dispatching a message for delivery to a particular recipient


180


. The messaging systems


150


may access the profiles


190


through real time communication with the data center


110


or by downloading the profiles


190


to the messaging system


150


for subsequent use. In a most preferred aspect of the present invention, the database of recipient profiles


190


is downloaded to each messaging system


150


at periodic intervals. During the message creation process (content creation, addressing, output generation, etc.), the messaging system


150


determines if a profile


190


exists for an intended recipient


180


. If not, then the messaging system


150


continues normal operation. On the other hand, if a profile


190


corresponding to the intended recipient


180


does exist, then the messaging system


150


utilizes the data


190




a


-


190




g


provided in the intended. recipients profile


190


to control the messaging process. For example, if the intended recipients profile


190


indicates a preferred form of communication in the message format data


190




b


, then the messaging selects that form of communication (if available). This has the benefit of allowing the intended recipient


180


to control the format of messages that it will receive. Those skilled in the art will recognize that not each type of messaging system


150


will be capable of executing each form of communication. As another example, if the primary address data


190




f


is different from the address that was previously available to the messaging system


150


, then the messaging system


150


adopts the address provided by the primary address data


190




f


. This has the benefit of providing faster updating of new addresses to senders and allows for updates to occur at a single source. Thus, the delays and costs associated with the traditional practices described above are substantially alleviated.




Delivery instruction data


190




c


may also be established by the recipients


180


and utilized by the messaging systems


150


to more efficiently route messages to the intended recipient


180


. If a temporary reroute messages instruction is provided, then the senders via their messaging systems


150


can utilize the secondary address data


190




g


as a destination address for the intended recipient


180


over a specified period of time. In this manner, delays and extra handling as discussed above are eliminated. If a hold messages instruction is provided, then the messaging systems


150


will not dispatch the messages for delivery. In this manner, the storage costs for the carrier are eliminated. Also, the sender has an opportunity to consolidate messages that are generated during this interval into a single comprehensive message at potentially less cost than dispatching individual messages. The messaging systems


150


may facilitate this by keeping a track of messages that have been held and giving the sender an opportunity to consolidate messages directed to the same intended recipient


180


that are waiting for dispatch.




The interest data


190




d


and the no interest data


190




e


may also be established by the recipients


180


and utilized by the messaging systems


150


to more effectively route messages to the intended recipient


180


. Using the interest data


190




d


, the senders may scan the profiles


190


looking for recipients that are likely to be interested in their messages (solicitations, informational communication, etc.). Thus, the senders would achieve greater effectiveness on their message delivery programs because they would have an indication the certain recipients


180


have a previously acknowledged interest in a particular industry or industries. On the other hand, using the no interest data


190




e


, the senders may also increase the effectiveness of their message delivery programs while reducing costs. While scanning the profiles


190


in general or accessing profiles


190


for recipients


180


that have already be designated to receive a message, the sender may terminate further processing of certain messages by out sorting any recipients


180


that have provided an indication that they are not likely to be interested in any messages (solicitations, information communication, etc.) from a particular industry or industries. In other words, messages intended for such recipients will be terminated (not generated, not dispatched, etc.). This may be achieved automatically by including in the messaging systems


150


an indication of the senders SIC number. Thus, the SIC numbers supplied by the recipients as no interest data may be compared with the SIC numbers assigned to the senders. Thus, the senders would save costs by foregoing to dispatch any messages to these recipients


180


. Additionally, these recipients


180


benefit in that they are not distracted by the receipt of undesired messages.




As an optional feature, an original sender that has been designated in the no interest data


190




e


by a recipient


180


may not necessarily terminate messages intended for the recipient


180


. The original sender may utilize the interest data


190




d


from of the recipient


180


to locate an alternate sender to serve as the primary contact with the recipient


180


. Thus, the original sender and the alternate sender may collaborate on dispatching a message to the recipient


180


. As an example, if a recipient


180


designates financial service companies in its no interest data


190




e


and home improvement companies in its interest data


190




e


, then a financial service company may partner with a home improvement company on sending a message to the recipient


180


. In this example, the home improvement company (alternate sender) may take the “lead” on the message by describing various home improvement products and/or services that it provides while indicating that, if needed, a second mortgage line of credit to cover the costs associated with the home improvements are also available from their partner (original sender). As another example, the original sender may still dispatch a message to the recipient without directly contacting a partner. To continue the theme introduced above, the original sender may focus the message on obtaining a second mortgage line of credit to cover the costs associated with the home improvements and then provide a listing of home improvement specialists in proximity to the recipients


180


.




Thus, it should now be understood that messages from senders falling into “no interest” categories might be modified in several ways. The examples have been discussed above are: (i) terminating the messages; (ii) redirecting the message as originating from a source other than the original sender; and (iii) editing the message to suit an interest of the recipient.




Based on the above description and the associated drawings, it should now be apparent that the present invention improves many aspects of the messaging industry by letting recipients directly control the flow of messages.




Many features of the preferred embodiment represent design choices selected to best exploit the inventive concept as implemented in a particular messaging environment as pertaining to individual private recipients. However, those skilled in the art will recognize that various modifications can be made without departing from the spirit of the present invention to adapt the concepts of the present invention to address situations where the recipient is a business. For example, a wide variety of database management tools exist that can facilitate access to the recipient preference profiles. The exact manner in which these activities occur is subject to great variation due to practical design choices of the hardware, software, communications and data involved. As another example, the control systems of the data center


110


and the messaging systems


150


may operate cooperatively such that various tasks and operations described above may occur at either location. As yet another example, the data center


110


may operate as the message dispatcher. Thus, the messaging systems


150


generate the messages and upload them to the data center


110


. Then, the data center reconciles the messages with the recipient preference profiles


190


and takes appropriate measures when dispatching or not dispatching the messages as discussed above.




Therefore, the inventive concept in its broader aspects is not limited to the specific details of the preferred embodiments described above, but is defined by the appended claims and their equivalents.
