Today's Email: Most powerful email metrics

The most powerful email metrics aren’t the ones everyone talks about.

Open rates. Click rates. Bounce rates. Unsubscribes. 📉

They’re fine—but they only scratch the surface.

The real growth comes from lesser-known metrics most marketers never track.

These hidden signals reveal which subscribers drive revenue, which channels produce the best customers, and where your strategy is leaking value.

I've analyzed thousands of campaigns, and the marketers who consistently outperform their competition dig deeper.

The real problem?

You're missing the granular insights that actually drive revenue.

Think about it - if you're only looking at overall open rates, you're treating your entire list as one homogeneous blob.

But your subscribers aren't all the same, are they?

So why are you measuring them that way?

Here are 6 metrics the email pros track that you probably don't:

✅ Open & click rates BY SOURCE
(Which acquisition channels bring your most engaged subscribers?)

✅ Revenue BY SOURCE
(Where are your highest-value subscribers coming from?)

✅ Open & click rates BY DOMAIN
(Are Gmail users more engaged than Outlook users?)

✅ Revenue BY DOMAIN
(Which email providers host your best customers?)

✅ Revenue PER SUBSCRIBER
(What's the actual value of each person on your list?)

✅ Open reach rate
(What percentage of your list opens ANY email over time?)

These metrics reveal the hidden patterns in your email program.

And guess what? When you understand these patterns, you can make strategic decisions that actually move the needle.

Your basic metrics aren't wrong - they're just incomplete.

Start tracking these advanced metrics, and watch your email strategy transform from guesswork into precision.

Best,
