Conditional Email Forwarding System Reduces Message Duplication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing email systems often duplicate messages by forwarding every email received at an internal address to an external address, leading to increased management burdens for users.
Innovation Solution
Implementing a system that conditionally forwards emails from internal to external addresses only after a threshold period, considering factors like message read status, thread activity, and user behavior, to minimize duplication and streamline message delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If every message received at the application-associated address is forwarded to the external address, then the user can access messages from both internal and external addresses, but the amount of messages the user must manage doubles and causes duplication
Solution Approach 1:
The system performs preliminary action by immediately removing the message from the internal address after successful forwarding to the external address. This prevents duplication by ensuring the message exists in only one location (external address) after the forwarding operation completes, thereby maintaining versatility while reducing the quantity of messages to manage.
Solution Approach 2:
The system extracts the message from the internal address space and places it in the external address space. By removing the message from the internal address after forwarding, the system separates the message management responsibility to the external address, eliminating duplication and reducing the total number of messages the user must manage.
2Ease of operation
If the application allows access to messages within the application environment only, then message management is simplified, but users cannot access messages outside the application
Solution Approach 1:
The system uses the external address as an intermediary that bridges internal and external message systems. Messages are forwarded to the external address, which acts as a mediator allowing users to access messages both within the application environment and externally, while the internal address removes the message after forwarding to maintain simplicity.
Solution Approach 2:
The external address serves multiple functions: it receives forwarded messages, allows external access to messages, and acts as the final destination after internal address removal. This multi-functionality enables the system to provide both simplified internal management and flexible external access simultaneously.
3Speed
If messages are forwarded immediately upon receipt, then delivery speed is improved, but unnecessary duplication occurs when users have already read the message
Solution Approach 1:
The system performs preliminary action by monitoring whether the user has read the message before forwarding. If the user has read the message, the system removes the message from the internal address without forwarding, preventing unnecessary duplication while maintaining fast delivery for unread messages that need to be forwarded.
Solution Approach 2:
The system uses feedback from user reading status to determine whether to forward the message. By checking if the user has read the message and using this feedback to control the forwarding decision, the system avoids duplicating messages that are already processed, thereby reducing the quantity of messages while maintaining efficient delivery for relevant messages.
Data Source
AI summary
A system is provided for conditionally forwarding electronic messages. Users of an online application or service are provided internal addresses (e.g., electronic mail addresses) within a domain (e.g., an Internet domain) of the application or service. When a message is received that is addressed to a user's internal address, it is queued for conditional forwarding to an external address of the user (e.g., an electronic mail address in a domain other than the domain of the application or service). After a threshold period of time lapses, if the message was not read via the online system (e.g., via web or mobile client software) it is forwarded to the external address. If additional messages were received for the same conversation or thread, they may be forwarded at the same time. Messages may be forwarded in their original form; multiple messages may be forwarded in digest form.
