Summary
Effectively tracking and preventing spam complaints from GSuite and Office 365 without dedicated IPs requires a multi-faceted approach, as direct access to complaint data from those providers is generally unavailable. The strategy revolves around proactive measures to maintain a healthy sender reputation and minimize the likelihood of emails being marked as spam. Key components include implementing email authentication protocols (SPF, DKIM, DMARC), maintaining good list hygiene through regular removal of inactive subscribers, setting up and actively utilizing feedback loops (FBLs) to identify and address problematic addresses, and monitoring engagement metrics such as open rates, click-through rates, and unsubscribe rates. Additionally, tools like Google Postmaster Tools can provide insights into email reputation and spam rates, helping to identify trends and potential issues. Enforcing double opt-in processes and ensuring content relevance are also crucial steps in preventing complaints and ensuring that subscribers are genuinely interested in receiving emails. Finally, maintaining a spam complaint rate below 0.1% is vital for a positive sender reputation.
