About Email Calculator

The problem we kept running into

Every email marketer we spoke to had the same frustration: they were sending campaigns, getting results, and then spending hours trying to make sense of them. Mailchimp has one dashboard. Shopify has another. Typeform has another. None of them talk to each other. So every week, someone exports data, pastes it into a spreadsheet, and manually tries to figure out what actually happened.

Email Calculator was built to fix that. Not just to show you open rates — but to give you the full picture: what you sent, who engaged, what converted, what it was worth, and how it compares to your last campaign. All in one place. No spreadsheet required.

What it does

Email Calculator sits between your tools and your brain. It connects directly to your email platforms, ecommerce stores, and lead generation tools via API, then pulls all that data together into one unified campaign view — with real calculations, benchmarks, and AI-powered analysis built in.

Connect platforms like Mailchimp, Klaviyo, HubSpot, Shopify, or Typeform once, or import campaign data in bulk via CSV. Then use Email Calculator to:

• Instantly calculate open rates, CTR, CTOR, conversion rates, and revenue per subscriber
• Compare campaigns side-by-side and benchmark against 43 industry standards
• See which campaigns actually drove revenue — not just clicks
• Get AI-generated insights and plain-English summaries of your results
• Schedule automated reports and share them with clients or leadership
• Export in PDF, Excel, Word, PowerPoint, and more

It doesn't replace your ESP or ecommerce platform. It's the layer on top — the place where all your campaign data finally makes sense.

Why it's different

Most email platforms show you activity — opens, clicks, sends. Email Calculator shows you performance: what those numbers mean, how they compare, and what to do next. There's a significant difference between knowing your open rate was 22% and understanding whether that's good, bad, what drove it, and how it affected revenue.

We also support Email, ROI, and Lead data in the same report — something most tools can't do at all. That means you can finally answer questions like: “Which campaign generated the most leads?” or “What's the revenue impact of our last promotional send?” — without stitching together three separate tools manually.

Who it's for

Email Calculator is built for anyone responsible for email marketing performance — whether that's a solo marketer at a startup, a CRM team at an ecommerce brand, or an agency managing campaigns for 20 clients. If you send emails and need to understand (or explain) the results, this is built for you.

It's particularly valuable if you:

• Spend more time building reports than reading them
• Track email performance across multiple platforms
• Need to show stakeholders or clients what your campaigns actually produced
• Want to move faster without hiring an analytics team
