Why are Yahoo FBL complaint dates showing weeks before notification dates in Amazon SES?

Email marketer from Reddit User MailGuru shares that Yahoo might be filtering or validating complaints before sending FBL notifications. This filtering process could introduce delays between when the user reports spam and when the FBL is generated.

Email marketer from Quora explains that there might be rate limiting on the yahoo FBL system to prevent abuse of the FBL reporting system.

Email marketer from StackOverflow User TechEmail raises the possibility of timezone discrepancies. The complaint date and notification date might be recorded in different timezones, leading to an apparent delay when the data is viewed in a unified timezone.

Email marketer from EmailDeliverabilityBlog says that the delay can be due to reputation issues if you are being rate limited due to your past sending history.

Email marketer from MarketingLand suggests that some inherent latency is expected with FBLs. ISPs prioritize other tasks and FBL generation might be a lower priority, leading to variable delays. Specific to Yahoo, there might be additional internal processes that add to this latency.

Email marketer from EmailMarketingTips says that if there is a large jump in spam complaints then there might be a list-bombing attack on your system and you need to check the sending metrics and investigate.

Email marketer from EmailGeekForum suggests the issue might be related to Yahoo's internal processing and reporting mechanisms. They mention that Yahoo might batch process FBL data, leading to the notification date lagging behind the actual complaint date.

Expert from Spam Resource suggests that Yahoo might perform extensive data processing and aggregation on FBL data before providing it to ESPs. This processing could involve de-duplication, filtering, and anonymization, leading to delays between the actual complaint and the FBL notification.

Expert from Word to the Wise responds that the timing differences in Yahoo FBLs specifically is often related to variations in how different ISPs process feedback loops, so look for general causes but remember Yahoo can act differently. They suggest exploring Yahoo's specific documentation for FBLs, but also examining Amazon SES documentation.

Expert from Email Geeks clarifies that the client is using Amazon SES and presumes the data is directly from Amazon. She also notes the availability of a third column containing "email date."

Expert from Email Geeks suggests that Amazon might be processing or altering the timestamps, as the client is likely retrieving JSON objects directly from Amazon, rather than parsing the complaints themselves. She mentions that the Amazon documentation indicates the presence of multiple timestamps within the JSON data.

Expert from Email Geeks raises a question regarding delays in receiving Yahoo FBLs (Feedback Loops). She is observing discrepancies in the complaint date and notification date, with the complaint date appearing weeks before the actual receipt by SES (Amazon Simple Email Service) for a customer. She provides examples of these date discrepancies.

Expert from Email Geeks specifies that the issue with different timestamps is specific to Yahoo complaints. In most other cases, the complaint and notification dates match. She will investigate the source of these timestamps with the client.

Documentation from Yahoo Postmaster states that while they strive for timely FBL reporting, processing times can vary. Factors like complaint volume and system load can influence the time it takes for a complaint to be reflected in the FBL data provided to ESPs like Amazon SES.

Documentation from Amazon SES FAQs explains that the speed of FBL delivery is dependent on the ISP (in this case, Yahoo). Amazon SES processes the data as soon as it's received, but cannot control the ISP's reporting timeline.

Documentation from RFC 6522 explains that the time it takes for ISPs to process and send feedback reports can vary greatly depending on their infrastructure, load, and policies. No specific timeline is guaranteed.

Documentation from Amazon Web Services explains that delays in receiving FBL data can occur due to processing times within Yahoo's systems and the subsequent transmission to Amazon SES. The complaint date reflects when the user marked the email as spam, while the notification date is when Amazon SES receives that information from Yahoo.

Documentation from Amazon Web Services states to use sending statistics in Amazon SES to help monitor any sending issues you may have, but it doesn't cover issues regarding when the data is being sent to you.
