Solution Overview

Problem

The challenge in electronic commerce is to enhance email open rates amidst the overwhelming presence of unsolicited messages, as existing methods fail to effectively ensure that legitimate emails are delivered and opened by recipients amidst SPAM.

Innovation Solution

A system and method that utilize a database of email addresses and open records to determine the optimal time for sending emails, embedding tracking codes to record open events, and updating algorithms to improve timing accuracy for future messages, thereby increasing the likelihood of emails being opened.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If emails are sent immediately or at fixed times, then delivery speed is improved, but email open rate deteriorates due to competition with SPAM

Engineering Contradiction:
Improveemail delivery speedVSAvoidemail open rate
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The system dynamically adjusts email send times based on recipient behavior patterns and SPAM timing data. Instead of fixed scheduling, the system continuously adapts send times to optimize open rates while maintaining delivery speed, resolving the contradiction between immediate delivery and successful opening.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system performs preliminary analysis of recipient email habits and SPAM patterns before sending emails. By pre-determining optimal send times based on historical data and predicted recipient availability, the system ensures emails are delivered at moments of highest open probability, improving open rates without sacrificing delivery speed.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If SPAM filters and manual deletion methods are used, then SPAM management is improved, but legitimate email open rate deteriorates due to accidental filtering

Engineering Contradiction:
ImproveSPAM management efficiencyVSAvoidlegitimate email delivery
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system implements feedback mechanisms where open rate data and recipient behavior are continuously collected and analyzed. This feedback loop allows the system to learn from past deliveries and adjust future send times to avoid periods when recipients are likely to use aggressive SPAM filtering, thereby protecting legitimate emails from being accidentally filtered while maintaining efficient SPAM management.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system acts as an intermediary between senders and recipients by intelligently timing email delivery. Rather than relying on recipient-side filters alone, the system mediates the delivery process by selecting optimal moments when emails are least likely to be filtered as SPAM, thus protecting legitimate emails while preserving recipient control over SPAM management.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If email sending is delayed to avoid SPAM times, then email open rate is improved, but delivery time increases

Engineering Contradiction:
Improveemail open rateVSAvoidemail delivery time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system changes the timing parameter of email delivery based on analyzed patterns of recipient behavior and SPAM send times. By dynamically adjusting the send time parameter rather than using fixed delays, the system achieves optimal open rates without unnecessary time loss, delivering emails at the earliest moment when open probability is maximized.

Inventive Principle:
Principle #35Parameter changes

AI summary

A method of increasing the likelihood an electronic message will be opened by a targeted recipient includes determining a time zone corresponding to an address of a targeted recipient and accessing an opening history for a set of electronic mail recipients within a domain including the targeted recipient. From the time zone and the opening history at least one of a time and a day are recommended for sending an electronic message to the target recipient to increase likelihood that the electronic message will be opened.
