Why Email Calculator?

“I already have Mailchimp. It shows me opens and clicks. Why do I need another tool?”

That's the most common question we get — and it's a fair one. Your ESP does show you data. But there's a gap between seeing data and understanding performance. Email Calculator fills that gap.

What your ESP gives you vs. what you actually need

Your email platform tells you: 22% open rate. 3.1% CTR. 450 clicks.

But it doesn't tell you:

• Is 22% actually good for your industry and list size?
• Is that better or worse than your last campaign?
• How much revenue did those 450 clicks generate?
• How many leads did the campaign capture?
• What should you change next time to improve?

Those questions require combining data from your email platform, your ecommerce store, your CRM, and your form tools — and then interpreting it together. That's the gap most marketers fill with spreadsheets, copy-paste, and guesswork. Email Calculator automates it.

The real problem: your tools don't talk to each other

A typical email marketer uses 3–5 tools: an ESP (like Mailchimp or Klaviyo), a store (like Shopify), a form tool (like Typeform), maybe a CRM. Each one has its own dashboard, its own metrics, its own definition of “a successful campaign.”

To get the full picture of one campaign, you have to:

• Log into your ESP for email stats
• Log into Shopify for revenue
• Log into Typeform for lead submissions
• Export all three into a spreadsheet
• Manually calculate the combined metrics
• Present it in a format someone else can read

Email Calculator replaces all of that. Connect your platforms once via API or import campaigns in bulk via CSV and it does the aggregation, calculation, comparison, and reporting for you — automatically, every time.

What Email Calculator actually does

Calculates the metrics your ESP doesn't touch

Open rate is easy. But what about revenue per subscriber? Email ROI? Click-to-open rate? Engagement score? Subscriber lifetime value? Email Calculator calculates all of these instantly — using proven formulas and your actual data.

Benchmarks your results against industry standards

Knowing your open rate is 22% is useless without context. Email Calculator compares your results against 43 industry benchmarks, so you know whether 22% is strong, weak, or average — for your specific sector and audience size.

Connects email performance to revenue and leads

This is the biggest gap in most ESPs. Email Calculator integrates with ecommerce platforms (Shopify, WooCommerce, BigCommerce) and lead tools (Typeform, Jotform, HubSpot) so you can see — in one report — which campaigns drove actual revenue and how many leads they generated.

Turns data into readable narratives

With the Stories feature, Email Calculator converts your campaign numbers into plain-English summaries you can share with clients or leadership without anyone needing to interpret a chart. It explains what happened, what performed well, what didn't, and what to do next.

Generates reports in one click

Export as PDF, Word, PowerPoint, Excel, or HTML — branded or white-labelled for agencies. No rebuilding the same report every week. Set it up once, automate, and share.

Who needs this

Email Calculator is most valuable when:

• You manage campaigns across multiple platforms — and switching between dashboards wastes time
• You report to stakeholders or clients — and need professional, clear outputs fast
• You track revenue or leads from email — and your ESP doesn't connect to your store or CRM
• You want to optimise, not just report — and need benchmarks and trend analysis to know what to improve
• You're running a team or agency — and need consistent, repeatable reporting across multiple accounts

It works alongside your existing tools

Email Calculator doesn't send emails, design templates, or manage lists. It doesn't replace Mailchimp or Klaviyo. Think of it as the analysis and reporting layer that sits on top of your entire email stack — pulling in data from 56+ platforms or bulk CSV imports and turning it into something you can actually use to make decisions.

Your stack has three jobs: Create → Send → Understand. Your ESP handles the first two. Email Calculator handles the third — and it's the part most teams skip, or do badly, because they don't have the right tool for it.

Still not sure?

Try it manually first. Take your last email campaign stats and run them through our free calculators — open rate, CTR, email ROI, revenue per subscriber. See what your numbers actually mean in context. Then consider what it would look like to get that automatically, for every campaign, with benchmarks and AI insights included.
