SendForensics

SendForensics tests your email against spam filters at Gmail, Outlook, Yahoo, and mobile carriers using real inboxes, then scores your SPF, DKIM, and DMARC alignment. It identifies misconfigurations that harm placement and recommends fixes, showing how your reputation ranks at each major ISP. Reports include detailed breakdowns of authentication gaps and anti-spoofing setup.

Designed for email marketers and agencies who need to understand why campaigns land in spam or the promotions tab. More specialized than all-in-one platforms, it works with any email service to audit configuration and optimize folder placement without requiring a full platform migration.
