This page presents information about the use of DMARC by the Alexa Top Sites. While Alexa curates a list of the one million most popular sites, we often examine smaller subsets to explore how the most popular sites compare to subsets including less popular sites.
This page is broken down into sections by the size of the subset of the Alexa top sites. Within that section, we present several views of the data we collected about the sites’ use of DMARC.
