Inbox Insight uses data from Return Path’s historical Consumer Network. This network was a collection of hundreds of thousands of real email users of consumer mailbox organization and optimization tools such as OtherInbox and Unsubscriber. Users of these consumer tools agreed to share their data anonymously in exchange for access to the tools. In aggregate, these users made up the Return Path Consumer Network. It provided email engagement and delivery data from these users at mailbox providers such as Google, Yahoo, and Microsoft, and is used in Return Path tools.
Through this data, Inbox Insight gives you visibility into your email program and competitor email programs with engagement metrics such as read rate. Because the data used in Inbox Insight is based on the actual historical behavior of email subscribers, Inbox Insight users have access to the exact same data from competitor email campaigns. This gives Inbox Insight users the ability to compare their campaigns with those of their competitors.
The Consumer Network data source was removed on January 31, 2020. Historical data remains available in Inbox Insight.
