Have you ever thought about packaging up the analytics you can derive from this into a product offering?

The inspiration you mentioned in another comment is the exact impetus that would make for a lucrative offering, particularly on the agency side. Things such as email cadence, offerings, screenshots of the specific emails, etc. Either at an individual brand level, rolled up to a pre-defined category, or allowing individuals to choose their own basket of companies to create benchmarks from. Would be really useful when creating pitches, but also for ongoing digest reports for competitive monitoring.

And that's just based off of re-packaging what you're already showing. There are lots of additional useful opportunities that would only varying levels of effort to unlock.
