How do I turn Gmail into a to-do list?

Gmail has a built-in road: drag an email onto the Tasks panel and it becomes a task that links back to the message. It's genuinely handy, and it stays inside Google's walls. If you want that task to also reach your phone, the car, and Slack, it needs to live on a list that goes more places.

Is flagging emails in Outlook enough?

A flagged email shows up in Microsoft To Do, which beats marking things unread. If your whole day runs through Outlook, it may be enough. The flags stop at email, though, so the promise made in a hallway or in Slack still has nowhere to land.

How do I stop re-reading the same five emails?

Turn each one into one line with a date, then mark it read. The re-reading habit fades in about a week, because the list is now doing the checking for you and the task shows up on its day. You only open the thread again when it comes back due.

Does 42 Todo! connect to email?

Yes, email connections come with the Personal plan, so the thing an email asks of you can land on your list with a date. And from anywhere else, adding it yourself costs one sentence, typed to ChatGPT or Claude, sent in Slack, or said out loud.

The to-do list hiding in your inbox

There are eleven emails in your inbox marked unread on purpose. You've read every one of them, some of them five times, because reading them again every morning is how you remember they exist.

That's a to-do list. It's the worst one you own, and it's currently running your week.

Marked unread again

The moves are familiar. Mark it unread so it stays bold. Star the ones from the boss. Leave the tab open so the count can glare at you. Some people forward emails to themselves at midnight, which is a reminder with extra steps and a little shame in it.

None of this is silly, because the need underneath is real. The email asked you for something, you can't do it right now, and you're trying to make the ask survive until you can¹. The inbox is just a terrible place to keep a promise.

What an inbox is genuinely good at

To be fair to email, it's great at what it actually is. Everything anyone has ever sent you, in one searchable pile, in order. When you need the attachment from March or the exact words somebody agreed to, the inbox delivers every time.

It's an archive with a doorbell. And archives are for looking things up, which is a different job from telling you what to do at 2pm on Thursday.

Why it can't remind you

An inbox keeps everything and reminds you of nothing. The email that needs an answer by Friday sits at the same brightness as a shipping notice, and every new message pushes your promises further down the page.

Worse, rereading is the only way to check what you owe, so you pay for the same eleven emails every single morning. By Thursday you've read the vendor's question six times and still haven't answered it, because reading it again was never the same thing as giving it a day.

One line with a date, the thread stays put

The fix isn't a fancier inbox, it's taking the task out of it. The email becomes one line on your list with a day attached, like "answer the vendor on pricing, thursday." The thread itself stays right where it is, findable when you need the details.

Then mark it read, because the deciding is done. Thursday morning the task comes back to you on its own, you open the thread, and you answer it once². The inbox goes back to being mail.

The email was never the task

It helps to notice that the email was never the task. "See attached" isn't a task. The task is "send legal the revised numbers," and it only exists once you've written it in your own words with a day on it.

That small translation is the whole skill, and it takes ten seconds an email. Do it for the eleven unread ones and the count drops to zero without a single reply written, because the promises now live somewhere that will actually bring them back.

Your inbox is where work arrives. It was never where work should wait.
