How does email engagement affect inbox placement for Microsoft and GWorkspace B2B emails?

Summary

Email engagement profoundly impacts inbox placement in Microsoft and GWorkspace B2B environments. High engagement, including opens, clicks, replies, forwards, and marking emails as 'not spam,' signals value and improves sender reputation, boosting deliverability. Conversely, low engagement, spam complaints, and inactive subscribers negatively affect sender reputation, increasing the likelihood of spam filtering. Mailbox providers such as Gmail and Outlook use engagement signals to refine filtering accuracy, but their measurements of engagement may differ from those of marketers. Feedback loops (FBLs) are crucial for monitoring and addressing spam complaints. B2B engagement strategies should focus on key decision-makers within organizations. Finally, third-party services like Proofpoint can impact delivery paths, and content relevance is essential for driving engagement.

Email engagement profoundly impacts inbox placement in Microsoft and GWorkspace environments. Both Gmail and Outlook utilize user actions, such as marking emails as 'not spam,' moving them to the inbox, reading, and replying, as signals to refine their filtering accuracy. Positive engagement improves sender reputation and the likelihood of inbox delivery, while negative engagement (reporting as junk or spam) weakens it. Feedback loops (FBLs) provide senders with reports on spam complaints, and monitoring/addressing these issues improves deliverability. Low engagement and high complaint rates result in a poor sender reputation, leading to increased filtering to spam folders.

  • Gmail uses Engagement: Gmail uses user engagement signals to determine email value and inbox placement.
  • Outlook uses Engagement: Outlook considers user actions as signals for filtering accuracy.
  • Positive Engagement Boosts Reputation: Positive user engagement strengthens sender reputation.
  • Negative Engagement Hurts Reputation: Negative user actions weaken sender reputation.
  • FBLs are Important: Feedback loops help improve email practices and user engagement.
