DMARC Manager protects domains from spoofing and phishing by managing DMARC, DKIM and SPF records and reporting on authentication results. It provides a domain configurator, a status dashboard, email source analysis, DMARC report aggregation, failure alerts, BIMI branding and SMTP-TLS reporting. It is now included in Plan 4 of 365 Total Protection, and a free trial is offered.

• Domain Configurator: sets up DMARC, DKIM, SPF and TLS for many domains.
• Status Dashboard: shows senders and DMARC pass or fail results.
• Email Sources Analysis: identifies which sources send mail for a domain.
• Report aggregation: combines recipient reports into one view.
• Failure Reports and Alerts: real-time data on failing messages.
• BIMI and SMTP-TLS: logo display and encrypted delivery reporting.

An enterprise on Microsoft 365 can discover forgotten senders using its domains before enforcing DMARC. An MSP can manage many client domains through the multi-tenant offering. A bank can display its logo with BIMI after reaching enforcement.

Manages DMARC, DKIM, SPF and TLS settings for multiple domains in one console. Shows unauthorised senders that use the domains. Helps bulk mail meet Yahoo and Gmail authentication rules. A free domain security check and a free trial reduce the cost of evaluation.

Yahoo and Gmail authentication rules make DMARC a baseline for bulk senders, and bundling DMARC with Microsoft 365 email security reflects demand for consolidated suites. MSPs and enterprises in Vietnam that run Microsoft 365 can fold domain protection into existing email security.

Legal notice lists entities in Germany, the UK, Spain, France, the US, Canada, Malta and Japan; no Southeast Asian office. Founding year not stated. The homepage cites over 750 specialists and 2026 awards including the MSP Today Product of the Year.
