Sendmarc is a cybersecurity company founded in Johannesburg, South Africa, by Sam Hutchinson, Keith Thompson, and Sacha Matulovich. The company specializes in DMARC (Domain-based Message Authentication, Reporting, and Conformance) implementation and management, with its core platform enabling businesses to configure and enforce DMARC, DKIM, and SPF email authentication protocols across multiple domains. The platform is designed to protect organizations against email phishing, spoofing, and domain impersonation by ensuring only legitimate emails from verified senders reach inboxes. It provides automated controls, reporting and visibility tools, and supports compliance with global email security standards. The solution targets businesses of all sizes, as well as Managed Service Providers (MSPs) and enterprise customers. In 2023, Sendmarc expanded its product portfolio beyond DMARC to include two additional solutions: Lookalike Domain Defense, which monitors and alerts on domains that mimic a customer's own domain; and Breach Detection, which monitors sources including the dark web for leaked credentials or compromised systems. The company operates a partner-focused channel model and offers hands-on training and enablement as part of its implementation process. Sendmarc received early investment from South African venture capital firm Kalon Venture Partners and has received recognition on the G2 software review platform as a High Performer in the Cloud Email Security category across EMEA markets.
