From Monitoring to Enforcement to BIMI

Why Choose Valimail

Unlimited SPF Lookups

Dynamic SPF technology has a 10-domain lookup limit, which isn’t enough for many organizations. That’s why Valimail automates SPF lookups.


Once you’re at enforcement with Valimail, proactively manage your DMARC status through custom alerts, so good email doesn’t get blocked.

DKIM Signature Validation

Valimail lets you add a DKIM key, ensures proper setup, including source IP so you reach and maintain enforcement with confidence.

Eliminate Need for IP Flattening

DNS updates are cumbersome, error prone, and lack validation. Valimail manages IP ranges so you don’t have to.

Brand Trust & Amplification

Our enhanced BIMI ad-on solution simplifies delivering secure, approved logos for authenticated communications and brand consistency.

Reputation / Brand Management

It’s not just the tech, it’s about protecting your reputation and your customers (from getting phished through fraud/impersonation).

Fastest time-to-enforcement

Email authentication requires continuous DMARC enforcement — most customers achieve it in four months or less.

The only dynamic SPF solution available

Valimail obscures SPF records from cyber-criminals so you’re not vulnerable to passive attacks.
