Email feedback loop

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
