We help teams get their emails into the inbox — reliably and repeatedly.
Kix6 builds fast, actionable deliverability intelligence for growth teams, SaaS companies and email operators. We combine inbox placement tests, DNS/auth auditing and blacklist monitoring to give clear fixes, not noise.
Our mission
To make email deliverability transparent and actionable so teams can spend less time diagnosing and more time growing. We surface the root cause and provide the exact DNS or content fixes required.
How we work
We run tests across major providers, evaluate authentication & domain configuration, and continuously poll public blacklists. Results are grouped into prioritized fixes — with copy/paste records for immediate deployment.
