Democratizing DMARC for every business on the internet

Making email authentication simple for every business, not just the Fortune 500. Every company sends email, but few do it securely. Suped turns DMARC, SPF, and DKIM into dashboards any team can read, so you can lock down your domains and keep phishers off your brand without hiring a deliverability expert.

Why Suped exists

Email authentication was built for a different era. DMARC, SPF, and DKIM are decades-old protocols, but applying them correctly across a modern stack - dozens of sending services, constant DNS changes, and Google and Yahoo tightening enforcement rules - has become a full-time job nobody wants.

We started Suped to fix that. Not with a dashboard that dumps raw XML aggregate reports in your lap and calls it monitoring, but with a platform that ingests reports, categorises senders automatically, flags the things that matter, and gets you to enforcement in weeks instead of the year-plus it takes manually.

Today Suped protects domains for teams of every size - from one-person startups to publicly-listed companies and the MSPs who manage email security for hundreds of clients.

Our founders

Suped was co-founded in early 2025 by Matthew Whittaker and Michael Ko, childhood friends from Canberra, Australia who'd both spent years in the email authentication space and grown tired of how fragmented, bloated, and anti-customer the DMARC tooling landscape had become. They set out to build the product they wished they'd had.

What we stand for

Simplicity

DMARC tools should be understandable on day one. Clear copy, clear dashboards, no jargon. If a feature needs a glossary to explain, we haven't finished designing it.

Automation over expertise

You shouldn't need to hire a deliverability consultant to get DMARC right. The product does the analysis; you get the decision.

Speed

We ship. Fixes and features land in days, not quarters. Customer asks move directly into the product, not a backlog.

Customer obsession

Founders still answer support tickets. Every conversation shapes what we build next.

Built in Sydney. Used everywhere.

Suped is headquartered in Sydney, Australia, with customers on every continent except Antarctica. Our team ships from Sydney and supports domains across North America, Europe, Asia, Oceania, and beyond.

Email authentication is a global problem. Google, Microsoft, and Yahoo enforce the same rules whether you're in Melbourne or Madrid, which means Suped works the same way wherever your customers are.
