So-called ‘Domain-based Message Authentication, Reporting, and Conformance’, or DMARC, is a technical standard that is designed to protect the senders and recipients of email from spam, spoofing, and phishing. Before you fall asleep, it’s worth pointing out that this is a booming tech sector.

What the fast-growing DMARC protocol is doing now is what “https” did the web: making email more communication secure. There were 6 million domains using DMARC in 2021 and 10m in 2022. It’s growing, fast.
