FREE TO USE
Carrier Signal Email Toolkit
At Carrier Signal, we run email deliverability and DMARC engagements for clients every week. We got tired of existing free diagnostic tools that are ad-heavy, login-walled, or missing details that matter when a rollout encounters trouble.
→ SPF, DKIM, DMARC, BIMI, and MX in a single view, no login, → SPF include chain fully resolved, with the RFC 7208 10-lookup count front and center (this is where “valid” records silently break during a DMARC rollout), → BIMI lookup included, for the folks getting questions about brand indicator, → A separate header analyzer that parses a raw Received/Authentication-Results chain and shows you where alignment broke — useful when a client forwards you a suspicious message and needs a real answer in ten minutes
