How many folders should you have in your mailbox?

A woman is sitting at a desk checking her email on a desktop computer, with a notification showing 12 new messages.

One of the areas I get asked about most often is email and in par­tic­u­lar what to do with all the emails you want to keep so that they are easy to find and that you do not have them in plain sight when you do not need them. Because, despite the rise of chat plat­forms, email is still a very cen­tral tool for the vast major­i­ty of us — and with that, a com­mon concern.


For you who prefer listening to reading, this post is also available as an episode of the ""Done!"" podcast:


This is enough

We often talk about fold­ers, my clients and I. What is a good fold­er struc­ture to have in the email inbox? Should you have one at all? If you should have one, how many fold­ers should there be and what should they represent?

My view can be summed up as fol­lows: have as few fold­ers as pos­si­ble, but enough.

At least one

I def­i­nite­ly rec­om­mend hav­ing at least one fold­er, such as an Archive fold­er, so that you can save any emails you need to keep after you have processed them some­where oth­er than direct­ly in the inbox. If you leave processed emails in your inbox, you risk see­ing emails you do not need to see at that moment when you are look­ing for emails you would like to find, which can make you think about oth­er dis­tract­ing things unnecessarily.

Instead, store emails some­where oth­er than the inbox, so that the inbox only con­tains emails that have not yet been dealt with, just as your phys­i­cal mail­box only con­tains unread morn­ing papers. (Now, if you get the impulse to email me and tell me that you are not dis­tract­ed at all by the old emails left in the inbox — try putting them away first. Per­haps you have for­got­ten what it felt like to work in a dif­fer­ent way than you do today?)

Seek, and you shall find

For myself, I get by just fine with a sin­gle Archive fold­er, as I am com­fort­able using the excel­lent search func­tions in emails (here is how to refine how you search in Out­look, for exam­ple). But, of course, you can have more fold­ers if you need to. You can have fold­ers for your var­i­ous projects, for the respon­si­bil­i­ties you have, for var­i­ous peo­ple you email often, or for any­thing else that is rel­e­vant to you.

Broad rather than narrow

If you nar­row­ly define what fold­ers should con­tain, they tend to grow in num­bers quick­ly and you end up with a long line of fold­ers to browse through when you need to save and find what you are look­ing for, which becomes cum­ber­some. It also increas­es the risk that an email con­tains infor­ma­tion that belongs in two dif­fer­ent fold­ers and you do not know where to put it, which ends up leav­ing it in your inbox for now” (and for so long that you end up not dar­ing to move it, because you have for­got­ten why you left it there in the first place). There­fore, define what you keep in which fold­ers in broad terms rather than narrow.

If you do not have enough fold­ers, which will result in you often hav­ing to search for the same word or term to see the emails you are inter­est­ed in, you would find them faster if they were sim­ply col­lect­ed in a fold­er rep­re­sent­ing that cat­e­go­ry (mean­ing that project, work­group, event, or the likes).

Cre­ate a struc­ture that suits you

You see — again, I do not want to assert a truth we should all sub­scribe to, but rather high­light the pos­si­ble con­se­quences so you can find the struc­ture and method that suits you best.

So, have as few fold­ers as pos­si­ble in your email but enough so that you can quick­ly find what you are look­ing for.

Do this

Does hav­ing too many or too few fold­ers in your email sound famil­iar? If so, ask yourself:

  • If you were to have as few fold­ers as pos­si­ble, but still some, how many would you need and what would they represent?
  • Could you merge some fold­ers if you cur­rent­ly have more than necessary?
  • If you cur­rent­ly have every­thing in your inbox, how about try­ing a dif­fer­ent stor­age loca­tion — if only for a few days? If you make a Tri­al Archive” fold­er and put all your old stuff in it for the rest of the week, you can move it all back lat­er if you are not com­fort­able with hav­ing it that way.

More order means more peace

If you opti­mize how you save emails you need to keep, emails become less of a has­sle. You will still be able to find what you need quick­ly, but you will not have the feel­ing of dai­ly puls­ing around in meter-high drifts of emails as often. If you save emails some­where oth­er than direct­ly in your inbox, you will expe­ri­ence (at least more often than not) the com­fort­ing peace that comes from mas­ter­ing the emails instead of them mas­ter­ing you.
