Summary
A high Gmail complaint rate is a critical factor negatively impacting sender reputation and deliverability, potentially leading to emails being filtered as spam or blocked entirely. Segmentation is essential to improve inbox placement by delivering relevant content to specific subscriber groups, increasing engagement, and reducing spam complaints. Effective strategies involve acquiring explicit consent, honoring unsubscribe requests promptly, providing valuable and targeted content, practicing good list hygiene, monitoring complaint rates, and utilizing feedback loops. While high engagement can offset negative impacts of complaints to a certain extent, low engagement coupled with high complaints is severely detrimental. Smaller sending volumes may experience more lenient treatment from Gmail regarding spam thresholds.
