Sendmarc DMARC Management

Sendmarc is an email authentication company led by co-founders Sam Hutchinson (CEO), Sacha Matulovich and Keith Thompson. It helps organisations stop attackers from spoofing their domains by moving DMARC, SPF and DKIM configurations to a strict enforcement policy.

The Sendmarc platform collects DMARC reports, shows which services send mail on behalf of a domain, and guides the domain to p=reject. It adds BIMI logo display, Lookalike Domain Defense and Breach Detection, plus multi-tenant management, PSA integration and co-branded notices for MSP and OEM partners. Customers include Luno, Prudential, Altron and Daily Maverick.

• DMARC reporting: collects reports and shows every sender using the domain.
• Policy enforcement: guides the domain to a strict DMARC policy.
• SPF and DKIM management: handled from the same dashboard.
• BIMI: displays the brand logo in supporting inboxes.
• Lookalike Domain Defense: detects look-alike domains of the brand.
• Partner tools: multi-tenant management, PSA integration and co-branded notifications.

A bank or fintech can move its customer-facing domains to p=reject to curb phishing sent in its name. An IT services provider in Vietnam can resell managed DMARC to SME clients. A retailer can combine DMARC with lookalike-domain detection for campaign mailings.

Moves a domain to enforced DMARC in stages, which reduces spoofed email sent in the company name. One dashboard covers DMARC, SPF and DKIM. A free trial and published certifications (SOC 2 Type II, ISO 27001) ease vendor review. A partner programme lets MSPs resell managed DMARC.

Google, Yahoo and Microsoft now require DMARC, SPF and DKIM for bulk senders, which pushes enforcement from optional to expected. Vietnamese banks, e-commerce firms and government bodies face spoofed email and brand impersonation, and managed DMARC services let MSPs serve them without in-house email specialists.

Certifications shown on site: SOC 2 Type II, ISO 27001, DMARC Certified. Headquarters and founding year are not stated on the pages fetched. Partnerships announced with Solid Systems (2025), Logicalis South Africa (2025) and ARMD.digital (June 2026).
