You run a work account, a personal account, a shared support inbox, maybe a client Workspace account, and an old iCloud address you can't quite kill. Five inboxes. You check them in rotation, all day, and you call this normal.
It is not free. It is not even close to free. The cost is not the time you spend clicking between apps. The cost is what switching does to your head.
Time cost is the wrong frame
Ask someone how much running five inboxes costs them and they'll estimate minutes. Twenty seconds to open the Outlook app, another twenty for Gmail, ten to check the shared inbox. Add it up: maybe four minutes an hour. Sounds tolerable.
That estimate misses the actual damage. The cost of switching contexts is not the switch itself, it's the re-entry. Every time you leave one inbox and open another, you have to re-establish what account you're in, what that account's threads mean, and whether anything there is urgent. That re-entry takes far longer than the click.
Researchers call this attention residue: part of your focus stays glued to the task you just left. Five inboxes means five partial re-entries every time you make a full loop. You never actually arrive anywhere.
What the tax actually buys you
Nothing. That's the part worth sitting with. Attention spent re-orienting between inboxes does not produce triage, replies, or decisions. It produces the feeling of being busy without the output.
A rough tally for someone running five accounts, checking each three times a day:
- 15 context switches a day, minimum.
- Each one costs a real re-orientation, not just a glance.
- None of that time appears on a calendar or a to-do list.
- All of it is gone by 6 p.m., unaccounted for.
You cannot bill this time. You cannot point to what it produced. It is pure overhead, paid in the currency you have the least of.
Why "just check one at a time" doesn't work
The standard advice is discipline: batch your inbox checks, one account per block, don't jump around. It's good advice and almost nobody can follow it, because the accounts aren't optional. A client emails your Workspace address. A vendor emails your personal one. The support inbox pages you regardless of what block of the day it is.
You can't schedule away multiple inboxes because the inboxes don't know about your schedule. The switching is imposed on you by other people's choice of address, not by your habits.
One window changes the math
The fix isn't fewer accounts. Most people can't consolidate five addresses into one without losing business relationships, aliases, or history. The fix is removing the switch itself: one merged window that shows every account's threads ranked by what needs you today, not five separate apps you have to open and re-learn in sequence.
That's the whole idea behind STAMP. Gmail, Google Workspace, Outlook, Microsoft 365, iCloud, Fastmail, Proton Bridge, plain IMAP: all of it lands in one inbox on your Mac. You never leave the window to check the next account, because there is no next account. There's one list, and it already contains everything.
The attention tax isn't the accounts. It's the doors between them.
What this actually saves
Not four minutes an hour. The re-entry cost, gone entirely, because there's nothing to re-enter. You open STAMP once and you're looking at every account at once, sorted by urgency instead of by which app you happened to tap.
The secondary effect matters too: fewer context switches means fewer chances for your brain to decide "this is a good moment to check Twitter instead." Every switch is a fork in the road toward distraction. Remove the switches and you remove the forks.
What to try this week
If you can't switch clients yet, you can shrink the tax manually. Pick one time of day, check every account back to back in one sitting, then close all of them until the next sitting. Don't interleave. The batching won't be as good as one merged window, but it beats fifteen scattered visits.
Better: see what a single window actually feels like. Pricing starts at $9 a month, with a 500-seat founding window while we're new.
