Sendmarc DMARC Managed Services is a multi-tenant platform designed for Managed Service Providers (MSPs) to deploy, enforce, and manage DMARC (Domain-based Message Authentication, Reporting, and Conformance) across multiple client domains from a single account. The platform works alongside SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to detect, quarantine, or reject fraudulent email messages, helping prevent domain impersonation, phishing, and spoofing. Key platform components include two portals: Customer Portal — Used to manage client domains with features including: - Multi-tenant domain management with role-based access - Consolidated reporting across all domains covering email sources, sender reputations, volumes, and threats - Real-time monitoring and configurable alerts - Guided task management to move domains toward a full DMARC reject policy - SPF Flattening to handle DNS lookup limits - SSO, 2FA, audit logs, and role-based permissions for account security - PSA tool and API integrations for billing and service desk automation - Co-branded white-label offering Partner Portal — Used for sales and lead generation, including: - An impersonation demo tool to show domain spoofing risk to prospects - A lead generation vulnerability checker widget - Opportunity scoring and risk-based lead prioritization - Online sign-up flows and marketing/sales enablement content The service supports compliance alignment with frameworks such as GDPR, PCI DSS, and HIPAA, and is offered as a recurring revenue model for MSPs.
