Frequently asked questions
How does Valimail help strengthen Office 365 email security?
Valimail helps organizations improve Office 365 email security by adding automated DMARC enforcement and sender identity protection to their Microsoft environment. While Microsoft helps protect users from inbound threats, Valimail helps ensure only trusted, authorized senders can send email on behalf of your domains, reducing spoofing and impersonation risk.
Why do organizations need DMARC for Office 365?
DMARC for Office 365 helps protect your domains from being used in phishing and impersonation attacks. Valimail automates the path to enforcement by identifying legitimate senders, simplifying SPF and DKIM management, and helping teams move from DMARC monitoring to enforcement faster and with less manual effort.
How do Valimail and Microsoft work together to improve phishing protection?
Valimail complements Office 365 phishing protection by securing the outbound identity layer that attackers often try to abuse. Microsoft helps defend inboxes from malicious messages, while Valimail strengthens Office 365 DMARC and Microsoft DMARC enforcement so unauthorized senders can’t spoof trusted domains. Together, Valimail Microsoft security workflows help organizations reduce impersonation risk, improve domain trust, and strengthen protection across the email ecosystem.
