Valimail Industry Leadership

employees looking at computer

Our commitment to restoring email trust.

With deep expertise in internet security and resilient infrastructure, the Valimail team regularly contributes to standards and threat detection communities — driving today’s email authentication policies and tomorrow’s cybersecurity advancements. We have a corporate commitment to lifting up the messaging industry as a whole and working collaboratively with partners throughout the ecosystem to restore trust to email.

We participate in several organizations working to make a difference.

We write and maintain open source code used by the largest mailbox providers (like Oath/Yahoo!) and make our contributions available to all, fixing issues in an accessible, scalable, global way.

We contribute to the protocols that continue to advance email and make it better for everyone.
