Above: Same campaign, two different reports

The Pattern

This isn't the first time.

Everyone built audiences by pouring years into content calendars, community management, follower growth. We were told to "build your community" and "own your audience."

Then Facebook organic reach went from 16% to 2%. Suddenly you had to pay to reach people who'd explicitly chosen to follow you.

That 100,000-follower Instagram account that was once considered an asset? If engagement is running at 0.1%, it still has value - but not the value the follower count suggested.

Email was supposed to be different. First-party data, direct relationships, no algorithm between you and your audience. The phrase "own your list" came to encapsulate the belief that first-party data could give marketers direct control, insulating them from platform whims.

Except email isn't exempt from platform dynamics. ISPs — Gmail, Apple Mail, Outlook — control delivery, filtering, and tracking just as completely as social platforms control reach.

The timeline:

• Apple Mail Privacy Protection (2021): Pre-loaded images to protect privacy. Metrics looked great, but measured Apple's bots, not humans.

• Gmail changes: Deliverability became inconsistent. Opens and clicks increasingly unreliable.

• Microsoft/Outlook adjustments: Increased filtering, more deliverability challenges.

When The Ad Contrarian, Bob Hoffman, started calling out digital metrics years ago, his criticisms sounded excessive at the time. In hindsight, watching email metrics degrade, he was both prescient and reasonable. (NB: Bob’s back, BTW)

What the Metrics Actually Hid

Here's what the collapse reveals: we misclassified what these channels actually do.

The metrics didn't lie about email's value, rather, they lied about what kind of value it was. High open rates looked like reach at scale. But they were measuring familiarity, not discovery. Engagement with people who already knew you, not introduction to people who didn't.

When measurement degraded, it didn't destroy value. It removed the illusion that retention scale equals market reach.

We'd been using retention metrics to justify growth strategies.

Your email list gives you reach to people who already know about you. Your Instagram followers are people who already found you. These are powerful retention tools—but they were never discovery tools.

At some stage, many businesses started thinking they didn't need media companies anymore, particularly SMEs or those with less resource. They had their own audience: followers, subscribers, direct access. The dashboards showed impressive numbers. Why pay for reach when you already owned it?

The measurement theatre made it all look the same.

We sell email and social products. We've benefited from those same dashboard numbers. We've used open rates in client reports. When the metrics degraded, we had to have uncomfortable conversations about what we'd been measuring all along.

But here's what we know works: we run client competitions through email that consistently generate 2,000-3,000 entries. If a retail sale campaign nets the sale of two premium pieces of furniture, that is massive ROI. That's measurable, verifiable behaviour.

We also sell access to our email database to advertisers. But here's the distinction: our audience trusts the publication. When we send them something, it carries editorial context and credibility we've built over two decades. That's different from a brand emailing its own list: ours delivers both retention value (our existing audience) and discovery value (introducing brands to people who trust our curation). Most businesses only have the first part.
