About Mailvovo
Our Mission
Make email authentication easier to understand, test and troubleshoot.
Why Mailvovo exists
Email authentication is important, but the evidence is often spread across DNS records, message headers, provider dashboards and report files. Mailvovo brings these checks into focused tools so domain owners and technical teams can see what is configured, what is observed, and what needs attention.
What we focus on
Clear technical results
Results are written to help people decide what to check next.
Privacy-conscious workflows
Inputs are scoped to the diagnostic task and unnecessary collection is avoided.
How we design our tools
Mailvovo separates configuration evidence, message evidence and report evidence. A DNS check can show what is published. A live email test can show what actually happened to one message. DMARC reports can show historical sending sources. Keeping those evidence types distinct makes troubleshooting clearer.
Our principles
Clarity
Use plain explanations and avoid overstating what a result proves.
Transparent results
Show whether evidence comes from DNS, a message header or a report file.
Responsible guidance
Never promise inbox placement or claim more certainty than the evidence supports.
