Troubleshooting spam placement in Google Workspace involves a comprehensive approach focusing on authentication, reputation monitoring, list management, and content optimization. Ensuring correct SPF, DKIM, and DMARC implementation is vital for verifying sender identity and preventing spoofing. Google Postmaster Tools and Sender Score are invaluable for monitoring sender reputation, spam rates, and feedback loops. Maintaining a clean and engaged email list through segmentation, regular cleaning, and double opt-in processes is crucial. Email content should be checked for spam triggers, personalization should be increased, and clear unsubscribe options provided. Encouraging recipients to add the sender to their contacts can also improve inbox placement. Standard deliverability work such as analyzing bounce patterns and suppression issues also remains important.
