Email Is Harder Than You Think

It doesn't just cost you time, it costs you clarity

Most people treat email like it’s the easy part of the day. The filler between blocks of real work. The thing you’ll knock out when you have 10 minutes.

That framing is costing you more than you think.

The Complaint That Started This

A coordinator I was working with mentioned that their executive director had to remind a senior leader — repeatedly — to read their emails. The leader’s response was that they were overwhelmed.

That’s a familiar kind of stuck. You’re behind, so you avoid. You avoid, so you fall further behind. And somewhere in there, you’ve convinced yourself that email isn’t real work — it’s the tax you pay to get back to the real work.

Email Isn’t Consumption. It’s Not Production. It’s Something Harder.

When you scroll social media or read an article, you’re consuming. Low obligation. No consequence. You don’t have to decide anything, respond to anyone, or track a single open loop.

When you write a proposal or work through a strategy doc, you’re producing. High effort, but coherent — one context, one goal.

Email is neither of those things.

Every message you open starts a real sequence: figure out who this person is and what they actually need, decide what the right response is, and write it in a way that moves things forward. Then do it again — different person, different project, different stakes.

That’s not light admin. That’s repeated context switching, which is one of the most cognitively expensive things a brain does.

Five Emails Is Not Necessarily Five Quick Tasks

Here’s the math people get wrong: they count typing time. They don’t count the thinking time before every response, the decision ambiguity when the right answer isn’t obvious, or the relational weight that comes with communication that actually matters.

A two-minute read can easily turn into a 20-minute response — not because you’re slow, but because figuring out what to say, to whom, and at what level of detail is real cognitive work. Do three to five of those in a sitting and you’re looking at 60–100 minutes of actual labor.

The reason inboxes pile up isn’t laziness. It’s that email is harder than it looks, and most people haven’t budgeted for what it actually takes.

You’ve Been Context-Switching Since You Woke Up

Here’s what makes it worse. Most people aren’t doing email in contained blocks — they’re checking it constantly throughout the day. Research consistently puts the average at somewhere between every 6 and 11 minutes.

That matters because of what Gloria Mark’s research found: after an interruption, it takes an average of 23 minutes to fully return to the task you were on. You don’t just lose the time you spent on the email. You lose the re-entry time too.

Do that math across a full workday and it becomes clear that most people aren’t experiencing occasional interruptions. They’re in a near-continuous state of context switching from the moment they open their inbox in the morning.

The mild brain fog that sets in by early afternoon, the feeling that you worked hard but can’t point to much — that’s not a focus problem. That’s the accumulated cost of dozens of incomplete cognitive resets.

This is also why keeping your to-do list in your inbox makes things worse, not better; you’re not just checking email, you’re re-entering a reactive state every time you open it.

Why Admin Blocks Are 30–60 Minutes

I’ve written before about admin blocks in time blocking — those dedicated chunks for processing email, returning messages, and handling the coordination work that keeps everything moving. My standard recommendation is 30–60 minutes.

Part of that has always been about affinity: most people have low enthusiasm for admin work, and after about an hour they get itchy to do something more engaging. That’s real.

But there’s a second reason I haven’t named until now. Fragmented cognitive load burns out faster than focused cognitive load. Decision fatigue accumulates with every context switch. After 30–60 minutes of rapid-fire context switching, response quality drops and avoidance goes up, even if you feel like you could keep going.

The admin block has a ceiling not just because admin is unpleasant, but because the cognitive cost stacks fast and quietly.

Once you’re inside your admin block, the S.T.A.R. method is the fastest way to work through what’s there — it’s built specifically for this kind of high-volume, fragmented processing.

Email Is Hard

Email doesn’t just cost you the time you spend on it.

It costs you the clarity you need for everything else.

Use the tips above to manage the hard better.
