Background

Valimail is the global leader in zero-trust email authentication. Since inventing hosted DMARC in 2015, Valimail has helped over 92,000 organizations stop phishing, protect their brand, and ensure email compliance. The platform is trusted by Fortune 500 enterprises, federal agencies, and fast-growing startups for its end-to-end automation, superior SPF tech, precision sender control, and fast time-to-enforcement.

Valimail’s approach centers on verifying sender identity, not guessing message intent. This makes it a vital part of layered email security alongside SEGs (Secure Email Gateways) and other tools.

Core services and solutions

• Valimail Monitor: A free, no-risk discovery solution that offers real-time visibility into domain authentication status and helps identify unauthorized senders. Getting visibility into your domain and setting up a policy of p=none is often the first step towards DMARC enforcement, and anyone can create a free Monitor account and instantly uncover insights into their domain. This solution is for everyone, from small businesses to enterprises and more. 
• Valimail Enforce: Accelerates DMARC enforcement by providing real-time insights and alerts to help you spot risky senders and automates DMARC, SPF, and DKIM – all in one place.. Most customers achieve p=reject in just a medium time of 45 days, making it weeks, or even months faster than competing approaches. Includes Precision Sender Intelligence, the largest known-good catalog of email senders, dynamic, real-time SPF management, and automated DKIM key management. 
• Valimail Amplify: Valimail Amplify is the only fully automated BIMI solution on the market. We streamline the process of acquiring and managing your Verified Mark Certificate (VMC) or Common Mark Certificate (CMC) and provide single‑click logo configuration for your domains. For companies already at DMARC enforcement, Valimail Amplify strengthens your brand’s credibility by fast-tracking your implementation of BIMI so you can have your brand logo appear adjacent to email messages in the inbox.

Technical focus areas

• DMARC: Automated policy enforcement, fast deployment, and continuous compliance.
• SPF: Our unique & patented SPF tech (Instant SPF) is automated, dynamic, and protected – ensuring:
  • Sender IP updates won’t mess up your SPF record, and you avoid legitimate email failing authentication. 
  • No manual DNS management – one click to enable or disable services.
  • SPF record in hidden so individual services can’t be targeted by bad actors
  • Changes take effect immediately.
• DKIM: Simplifies key management and monitoring, though downstream message changes may still cause failures (a known DKIM limitation).
• BIMI: Full support for BIMI implementation (requires DMARC enforcement, a VMC, and trademarked SVG). Outlook limitations may reduce visual ROI for Microsoft recipients.
• DNS management: Valimail’s architecture uses DNS delegation to deliver hands-off automation, though some users may prefer more control.
• Email authentication: Valimail’s Zero Trust Anti-Phishing approach verifies sender identity rather than guessing intent. With complete automation, strong integrations, and visibility tools, Valimail ensures only authorized messages reach the inbox—eliminating exact-domain impersonation and improving deliverability across your ecosystem.
