I’ve been working around email marketing teams for a while, and one thing keeps coming up that feels strangely unchanged: reporting still takes a huge amount of time.

In many teams, email performance reporting takes ~1–2 days per week when you include:

- Pulling data from multiple platforms (ESP, analytics, ecommerce) - Reformatting it for different stakeholders - Answering follow-up questions like “why did revenue drop?” or “how does this compare to last month?” - Rebuilding the same reports repeatedly in slightly different ways

What’s interesting is that the actual data exists instantly—but the interpretation + presentation layer is still mostly manual.

A lot of this isn’t the tool’s fault. It’s more about:

- Different stakeholders needing different views of the same data - No shared “language” for email performance reporting - Repetitive context-switching between analysis and explanation

I tried to map this out and simplify it into something more “on-demand,” where marketers can answer common reporting questions without rebuilding the same logic every time.

I ended up putting together a small tool to explore this idea: https://emailcalculator.com/

I’m more interested in whether others are seeing the same operational drag in email reporting, or if most teams have already automated this cleanly.
