This article explains what feedback loop data is, how eMarketeer uses it, and how you should act on the information provided.
What it means
A feedback loop is a mechanism used by some email service providers (ESPs) and reputation services to share third-party reputation signals about email sending behavior.
These signals are aggregated from external sources and may include indicators such as:
-
Spam complaint trends
-
Sender reputation changes
-
Engagement-related signals
eMarketeer collects and aggregates this feedback loop data to help identify potential deliverability issues early.
Why it matters
-
Feedback loop signals can indicate emerging deliverability problems before they result in blocked or filtered mail.
-
Ignoring negative signals can lead to reduced inbox placement or sending restrictions.
-
Acting early helps protect both your sender reputation and your ability to continue sending email.
Feedback loop data is a proactive warning system — it does not directly block sending, but sustained negative signals may contribute to enforcement actions.
What you should do
If you receive feedback loop warnings or guidance, take action immediately by:
-
Cleaning your contact lists and removing inactive or unengaged recipients
-
Reducing sending volume temporarily if volumes have increased rapidly
-
Adjusting sending frequency and patterns
-
Reviewing recent campaigns for relevance, expectations, and opt-in quality
-
Ensuring complaint and bounce rates remain low
