Email Bounce Detection and Abuse Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to effectively detect and mitigate undeliverable and unsolicited emails, leading to data transmission problems and increased costs for internet providers due to high volumes of spam, which obstructs the delivery of desired emails and requires more expensive infrastructure.
Innovation Solution
A software combination including import, opt-in, message delivery, bounce detection, and abuse mitigation software components that check email lists against databases of undeliverable and spam reports, defer or delay email distributions based on bounce and spam limits, and alert administrators to review accounts, ensuring only valid emails are delivered and reducing unnecessary data flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If email distributions are sent to large contact lists, then reach more potential customers, but increase the volume of undeliverable and spam emails causing data log jams and infrastructure costs
Solution Approach 1:
The system performs preliminary actions by checking email addresses against bounce databases and spam reports before sending email distributions. The opt-in software verifies contact validity in advance, and the bounce detection software pre-identifies undeliverable addresses, preventing harmful emails from being generated in the first place
Solution Approach 2:
The patent introduces intermediary software components (opt-in software, bounce detection software, abuse mitigation software) that act as mediators between the email sender and recipients. These intermediaries filter and validate email addresses, blocking undeliverable and spam emails before they enter the data transmission network
2Speed
If infrastructure capacity is increased to handle high volumes of email traffic, then maintain delivery speed, but increase costs for internet providers
Solution Approach 1:
The system extracts and removes harmful elements (undeliverable emails, spam, bounced emails) from the email traffic stream before they consume network resources. By taking out these problematic emails through filtering and validation mechanisms, the system maintains delivery speed for legitimate emails without requiring proportional infrastructure expansion
3Reliability
If bounce detection and abuse mitigation are implemented, then reduce undeliverable emails, but increase processing time for email distributions
Solution Approach 1:
The system performs validation actions preliminarily by checking email addresses against databases of known bounced addresses and spam reports before initiating email distributions. This advance verification ensures high deliverability while minimizing the time impact during actual email sending, as the heavy processing occurs beforehand
Solution Approach 2:
The system applies partial validation by focusing detection efforts on high-risk email addresses (those in bounce databases or spam reports) rather than uniformly validating every address. This selective approach maintains reliability for problematic emails while reducing overall processing time
Data Source
AI summary
Systems and methods of the present invention provide for detecting and mitigating abuse of undeliverable email or “bounced” emails. An administrator may import a list of email addresses for one or more contacts. The opt-in software may determine if each email address in the list of email addresses is opted in to receive an email distribution, and if so, a bounce detection software may determine if each email address is found in a database of known undeliverable or “bounced” email addresses. If so, an abuse-mitigation software may defer importing the list of email addresses and display an alert referring the administrator to an abuse department for review of the account. A message-delivery software may deliver the email distribution, and the bounce detection software may then determine whether undeliverable emails in the email distribution exceed one or more “bounce limit rules,” and if so, the abuse mitigation software may delay delivery of the email distribution and display an alert referring the administrator to the abuse department for review of the account. Otherwise, delivery may continue to completion.
