## Title
Localized time zone delivery system and method

## Abstract

In a preferred embodiment, the objective is to give an e-commerce system user control over when a message is sent so that it arrives at a time that is relative to a subscriber's local time zone. This gives users the ability to send messages to subscribers so that they are received by subscribers at a specific time of day in their time zone. For example, localized time zone delivery would send messages so that they are arrive in the inbox of subscriber “A” located in San Diego around 10:00 AM Pacific Time and around 10:00 AM Eastern Time for subscriber “B” who is located in Boston. Furthermore, localized time zone delivery allows system users to assign a time zone preference value to subscribers in their e-commerce system account.

## Background
This application claims the benefit of U.S. Provisional Application No. 60/869,863 filed 13 Dec. 2006, entitled “Localized Time Zone Delivery System and Method,” which is incorporated herein by reference.


FIELD OF THE INVENTION
The present invention relates to electronic messaging systems for use on the internet. More particularly, the present invention relates to a system and related tools for time zone based delivery of messages.
BACKGROUND OF THE INVENTION
A uniform resource locator (URL) for a website can usually be accessed from anywhere at any time. However some types of information may be dependent on time. For example, broadcasts are usually viewed by local municipalities and regions. In another example, certain sports broadcasts are “blacked out” regionally due to poor local ticket sales. Furthermore, some broadcasts are restricted by time zone. For instance, election results are often controlled by time zones.
Standard time zones can be defined by geometrically subdividing the Earth's spheroid into 24 lunes (wedge-shaped sections), bordered by meridians each 15° of longitude apart. The local time in neighboring zones is then exactly one hour different. However, political and geographical practicalities can result in irregularly-shaped zones that follow political boundaries or that change their time seasonally (as with daylight saving time), as well as being subject to occasional redefinition as political conditions change. Additionally, there are variations of the definitions of time zone which generally fall into two meanings: a time zone can represent a region where the local time is some fixed offset from a global reference, or a time zone can represent a region throughout which the local time is always consistent even though the offset may fluctuate seasonally.
An obvious surge in worldwide communication over the years has increased the need for interacting parties to communicate mutually comprehensible time references to one another. Sophisticated e-mail clients may have all sorts of bells and whistles, but at the core, e-mail clients basically just send simple text messages to recipients. In the beginning and even today, e-mail messages tend to be short pieces of text, although the ability to add attachments now makes many e-mail messages quite long. Even with attachments, however, e-mail messages continue to be text messages. Email clients show lists of all of the messages in mailboxes by displaying the message headers. The header shows who sent the mail, the subject of the mail and may also show the time and date of the message and the message size. They let a user select a message header and read the body of the e-mail message. Also, they allow the user to create new messages and send them.
E-commerce companies love e-mail, and for good reason. Production costs are low; results are immediate. Personalized e-mail are messages that consumers sign up to receive or that companies can target at customers based on their previous purchases. Furthermore, targeted e-mail marketing requires a much bigger investment than simply blasting out untargeted e-mail messages because it involves sophisticated databases and statistical modeling.
Targeted e-mail is also more prone to error. Sending a personalized message to the wrong person can ruin a relationship for life. So can a message that overloads a customer's computer. But as long as the e-commerce company chooses the right words and format, experts agree that talking to customers is not only good for sales but also good for name recognition. Any excuse to interact with your customer is healthy for the brand, and targeted e-mail seems to be one of healthiest direct-marketing ways to build brand equity.
Accordingly, the ability to market a product or service to individuals who are accessible on the Internet is becoming increasingly important. Email systems exist today for sending email to a target set of email addresses for purposes such as marketing, information acquisition, and otherwise. A system for sending email to a number of email targets for such purposes may be called an email campaign.
Thus, it would be desirable to have a system and a method for regional and time zone based messaging that addresses the inefficiencies of conventional approaches and provides further enhancements to message distribution.
The present invention provides a solution to these needs and other problems, and offers other advantages over the prior art.
BRIEF SUMMARY OF THE INVENTION
In a preferred embodiment, the objective is to give an e-commerce system user control over when a message is sent so that it arrives at a time that is relative to a subscriber's local time zone. This gives users the ability to send messages to subscribers so that they are received by subscribers at a specific time of day in their time zone. For example, localized time zone delivery would send messages so that they are arrive in the inbox of subscriber “A” located in San Diego around 10:00 AM Pacific Time and around 10:00 AM Eastern Time for subscriber “B” who is located in Boston. Furthermore, localized time zone delivery allows system users to assign a time zone preference value to subscribers in their e-commerce system account.
Additional advantages and features of the invention will be set forth in part in the description which follows, and in part, will become apparent to those skilled in the art upon examination of the following or may be learned by practice of the invention.

DETAILED DESCRIPTION
In a preferred embodiment, localized time zone delivery system and method gives an electronic commerce (e-commerce) system user control over when a message is sent such that it arrives at a time that is relative to a subscriber's local time zone. Thus, it gives users the ability to send messages to subscribers so that they are received by subscribers at a specific time of day in their time zone. It will be understood that a user can be a customer, administrator, customer representative, or client.
Referring now to FIG. 1, an overview diagram 100 is shown. Localized time zone delivery system and method sends messages so that they arrive in the inbox of subscriber “A” 116 located in San Diego around 10:00 AM Pacific Time and around 10:00 AM Eastern Time for subscriber “B” 118 who is located in Boston. Subscriber “C” 120 would receive the message 10:00 AM Central Time located in Oklahoma City. Furthermore, localized time zone delivery allows system users to assign a time zone preference value to subscribers in their e-commerce system account. As shown in FIG. 1, an email client 102 links 104 to a communication network 108. The email client 102 is an application used to send, receive, store and view e-mail. The communication network 108 passes 110 data to an email server 106. The email server 106 is a computer program or software agent that transfers electronic mail messages from one computer to another. Thereafter, a localized time zone delivery manager 114 works 112 integrally with the email server 106 to construct a particular time zone specific message. This message will be relative to a subscriber's local time zone.
Table 1 describes some commonly used terms in this industry. Furthermore, definitions in the following table are intended to clarify terms and concepts used within this document.

In a preferred embodiment, localized time zone delivery system and method also modifies a user interface for sending and mail processing for scheduled messages. This allows a user to specify that the message be sent to subscribers according to their local time zone preferences. The options displayed for time zones that have already occurred can be either “time zones past are sent immediately” or “send next available time (sometime next day)”.
Referring now to FIG. 2, a subscriber sign-up page is shown. Under a List Management tab 122, a subscriber's contact information may be added. For instance, First name 124, Last Name 126, Email 128, Address 130, City 132, State 134, Zip 136, Work phone 138, Home phone 140, Fax 142, and Country 144 are some fields that may be included for contact information. It will be understood by one of ordinary skill in the art that the subscriber sign—up page could also be a subscriber profile page, import process page, and export pages. These pages can be utilized in an email campaign system. Localized time zone delivery displays country level mapping of time zones included within the subscriber sign-up page. It displays “Time zone” values in the format of “00:00 AM/PM” (Relative to GMT). The subscriber sign-up page as shown includes “Time zone” fields 146. There is a default system action that is used in the sending process if subscribers in a segment do not have a value in “Time zone” fields 146. By selecting a value in a drop down menu under the “Time zone” field 146, localized time zone delivery system will be able to send messages to the subscriber based on their local time. Finally, Email format 148 allows a user to select which type of email they prefer.
FIG. 3 shows an email editor page. In another embodiment, the user may make changes to the scheduled message sending, retrieval, and statistical pages. Scheduled messages may include new rich text, message wizard, and advanced message types. Retrieved scheduled messages include Rich Text, message wizard, and advanced message types. Window 150 is where the user can enter text to be sent in the message to the subscriber. Section 152 is where the user may specify how many emails to send and which to skip. Section 154 in the email editor page is where the user can click whether or not to send information based on the local time zone of the subscriber. They can send the message today or enter a particular date. Show links and Save 156, Save draft 158, and Continue 160 are buttons the user can click after entering the above information to save and move forward in the message sending process.
Additionally, FIG. 4 illustrates a warning page 162 that occurs before scheduled messages are sent out to subscribers. Text 164 warns the user if the scheduled message is being sent in a time already passed in some time zones. If so, the user may opt to send those particular messages out immediately, and the timely messages during the proposed time zone periods. Edit message 166 button and Send now 168 button are options for the user to click to edit or send the messages. The user may also preview HTML, rich text, plain text, or America Online (AOL) messages by clicking on the pertinent links shown in FIG. 4. Other information about the message such as To, From, Subject, Subscribers, Send Date, Billing Codes, Footer, Message Notes, Spam Score, and HTML consultant is also noted on the warning page 162. Dynamic content may also be included in the personalized message.
FIG. 5 illustrates a subaccount page 170. In another preferred embodiment, localized time zone delivery can be activated and deactivated in administrative and sub account management pages which makes localized time zone delivery appear and disappear in client and sub accounts pages. In the subaccount page 170, there is a list 172 of features which do not appear in menu dropdowns. Here the user can click Time zone localized delivery 174 to remove the option from menu dropdowns. Clicking Submit 176 would save the changes made on this page 170. It will be understood by one of ordinary skill in the art that this page 170 is an example of a sub account or reseller page, and that localized time delivery can be modified to fit any e-commerce business system for sending messages. Full administration activates localized time zone delivery for client accounts and reseller accounts. If a client account has option, the user can activate the option for the particular client account's sub accounts. Moreover, if a reseller account has the feature, the user can activate the feature for one of their resale client accounts. If the reseller's client account has the feature, that client account can activate it for that client account's sub accounts.
In another embodiment of localized time zone delivery system and method, the user is capable of searching by “Subscriber Time zone”. Furthermore, the user can view and send by a listing of “Daylight” savings time zones. Localized time zone delivery has fields that capture subscriber internet protocol (IP) information in various parts of the system for use in geo-location projects. It will be evident to one of ordinary skill in the art that not all subscribers will have a default time zone value. There will be cases where a message will be sent to groups that include subscribers without a value in the “Subscriber Time zone” field.
The user may set a policy for the feature that requires users who are creating and editing recurring or scheduled messages to set the send time for these messages a minimum of four hours before the message is scheduled to be first sent in a time zone. For example, if a customer would like to use the time zone day parting feature to deliver a message to all subscribers at 4:00 PM (relative), then they must schedule the send in the system before 12:00 Pacific time.
In summary, the localized time delivery system utilizes a database with customer profile data where each customer record includes an email address and time zone information. It will be understood by one of ordinary skill in the art that the current time zone information can be determined by a variety of methods and systems, one of which includes an email campaign manager. The localized time zone delivery utilizes user input to create rules that ultimately send messages on regular intervals based upon that time zone information. The email campaign manager will send personalized messages to customers based upon these rules and time zones. The personalized messages may have dynamic content and be editable in an email editing system or module. Tables 2 and 3 describe requirements for user interface and use cases.

TABLE 3







Use Cases










ID
Use Case







1.
A marketing user has found that their messages have




the most impact when they are sent so that they arrive




close to 8 AM in their subscribers' inboxes. The user




creates a message and through the use of the new




feature, sets the time for the message to be sent so that




the message will arrive around 8 AM in the time zone of




each of the subscribers on the mailing list.



2.
A marketing user would like to begin using the Time




Zone Day Parting feature with their account. The user




sorts their list of subscribers in their in-house database




by locale and adds a column for time zone preference.




The user then imports that list into the system so that the




time zone value is added to each subscriber's record.



3.
A user retrieves a recurring message from the system




and decides that they would like to begin using the time




zone day parting feature. The user selects the Time




Zone Day part radio button and selects the time




(relative) that they would like the message to be




delivered in each subscriber's time zone. If the system




detects that the user's scheduled time is less than four




(4) hours away from current time, then:




The system asks the user to change the scheduled




time to allow for more than 4 hours before the first




Pacific time zone sending or . . .




Alerts the user that some users will receive the




recurring message in the next business day.



4.
A user creates a scheduled message in the system and




decides that they would like to use the time zone day




parting feature. The user selects the time zone day part




radio button and selects the time (relative) that they




would like the message to be delivered in each




subscriber's time zone. If the system detects that the




user's scheduled time is less than four (4) hours away




from current time, then:




The system asks the user to change the schedule




time to allow for more than 4 hours before the first




time zone sending because some recipients will not




receive the message if the time the user selected is




used.
