Why am I seeing 0% in Gmail Postmaster Tools Feedback Loop?

Email marketer from Reddit shares that it could indicate that the volume of emails being sent doesn't reach a threshold for Google to generate feedback loop data, or that the spam complaint rate is too low to trigger reporting.

Email marketer from Litmus responds by saying, although not explicitly stated, the absence of data might indicate the sending volume hasn't reached Gmail's threshold for reporting, or that complaint rates are very low.

Marketer from Email Geeks explains that if you see campaigns flagged in the FBL, then they may need modification. If not, then it's a case of "no news is good news." Your mailstream may still need work, of course, just not based on that data point.

Email marketer from Stack Overflow responds by saying the correct configuration of SPF, DKIM, and DMARC, along with the `Feedback-ID` header, is crucial; a misconfiguration could lead to data not appearing in Postmaster Tools.

Email marketer from email.geeks.chat explains that Gmail's aggregate Feedback Loop is designed to show anomalous campaigns with high complaint rates that may require action, rather than displaying data for all campaigns daily; seeing nothing could mean 'no news is good news.'

Email marketer from Mailgun shares that to ensure proper feedback loop reporting, it's important to correctly set up `Feedback-ID` headers, maintain consistent sending IPs, and monitor complaint rates to identify and address potential deliverability issues.

Email marketer from email.geeks.chat explains that it is normal for an individual sender to see 0% with no bar chart, ideally seeing a `Feedback Loop spam rate` of 0% and a `Feedback Loop identifier count` of 0 too.

Email marketer from Email on Acid explains that in Gmail Postmaster Tools, checking the volume of emails sent and the spam complaint rate can help you understand why the feedback loop is showing 0%. Low volume or minimal complaints could be the reason.

Marketer from Email Geeks explains that it is normal for an individual sender to see 0% with no bar chart. An individual sender should ideally see a `Feedback Loop spam rate` of 0% and a `Feedback Loop identifier count` of 0 too.

Marketer from Email Geeks explains that Gmail's aggregate FBL was designed to only show anomalous campaigns with high complaint rates that you might want to take action upon and is not designed to show the complaint rates for all campaigns every day. He frequently sees domains with nothing in the GPT FBL, even if their total complaint rate spikes up to 0.3% or more.

Expert from Spam Resource explains that seeing 0% in Gmail Postmaster Tools is not necessarily an issue. Low volumes of email or a very low complaint rate could result in no data being displayed. It could simply mean there's no significant negative feedback to report.

Expert from Word to the Wise responds that Gmail (and other providers) have volume thresholds before they start generating data in feedback loops, and a low complaint rate relative to the volume can also mean data isn't shown. A small test may well not generate data, even if it has a couple of spam complaints, because a couple of complaints out of 10 emails is clearly different to a couple of complaints out of 10,000 emails.

Documentation from Google Help explains that a 0% Feedback Loop spam rate and a 0 Feedback Loop identifier count are ideal for individual senders in Postmaster Tools, suggesting no user-reported spam for identified campaigns.

Documentation from SparkPost explains that Feedback Loop (FBL) identifiers not appearing may indicate an issue with implementation, volume not meeting the reporting threshold, or very low spam complaint rates.

Documentation from RFC mentions that the Abuse Reporting Format (ARF) is used to report feedback about received email, which may include spam complaints; a lack of ARF reports could indicate low complaint rates.
