  • TO IGNORE Noise or low value

The problem (for real)

You are not just short on time.

You lose energy deciding:

  • is this email important?
  • do I need to handle it now?
  • can I ignore it?

In the end:

  • you open too many emails “just in case”
  • you worry about missing the one that matters
  • everything starts to feel urgent

Key insight

The real problem with email is not volume.

It is decision fatigue.

The solution

Siftbox adds a simple layer on your inbox. Each email is classified with an explanation — you see what counts immediately.

URGENT

Immediate priority

What needs to surface right now.

IMPORTANT

Worth serious follow-up

Not necessarily for today, still important.

TO READ

When you have time

Interesting, no urgency.

TO IGNORE

Noise or low value

Newsletters, nudges, obvious spam — you keep the final say.

How it works

  1. 1

    You connect Gmail

    The account you already use every day.

  2. 2

    Siftbox classifies new messages

    Four clear buckets; you stay in your usual client.

  3. 3

    You decide faster

    Less hesitation, more control over your attention.

Reassurance

Siftbox never deletes your email.

You always stay in control.

Every decision is explainable.

You can correct at any time.

Frequently asked

It can. That is why the system is cautious: every classification is explained, and you can correct it.

Neither do we. Siftbox does not replace your inbox — it helps you see more clearly.

At first, yes. Then the system learns and gradually reduces the mental load.

No. Nothing is wiped automatically. You decide as you do today.

The minimum needed to run the service, in a restrained and documented way — not a full copy of your mail history.

Benefits

  • less noise
  • less hesitation
  • less stress
  • more clarity

Who it is for

If your inbox carries part of your mental load, Siftbox is first for:

  • Freelancers and independents.
  • Leaders of small teams.
  • Anyone overwhelmed who wants clarity without a heavy tool.
