How it works

From inbox to filed, in three moves

Every message takes the same short path. Read, considered, then filed with confidence — or held back for a quick look.

  1. 01

    Mail arrives

    A Microsoft Graph webhook fires the moment a message lands. mailbud picks it up in the background; your inbox is untouched.

  2. 02

    The AI reads it

    It weighs the email against the categories you described, guided by your past decisions, and scores the best fit.

  3. 03

    It gets filed

    Confident? Moved to the right folder automatically. Unsure? Held in a review queue with its reasoning attached.

Why mailbud

An organizer that thinks the way you do

Plain-language categories

Describe a folder the way you'd explain it to a colleague — “invoices and payment reminders”. No filters, no regex, no rules to maintain.

Automatic folder filing

Confident mail glides straight into the right Outlook folder, nested under a prefix you choose. A clean inbox without a single click.

A review queue for the rest

Anything ambiguous waits in a small queue with the AI's reasoning shown. Approve, reassign or dismiss — every choice teaches the next read.

Self-learning

Your corrections become private examples that sharpen future classifications. It gets more like you, the more you use it.

Private by default

Tokens encrypted with AES-256. Your mail is read to classify, never used to train any AI model, and never shared.

Never sends for you

mailbud only reads and files. It never replies, forwards or sends a single message on your behalf. Full stop.

The review queue does the doubting, so you don't

Good automation knows its limits. When mailbud isn't sure where an email belongs, it doesn't guess — it sets it aside and shows you why.

You stay in control of the edge cases while the obvious 90% files itself. Clear the queue in seconds with the keyboard.

  • See the AI's reasoning and confidence on every held email
  • Approve, reassign or dismiss — one keystroke each
  • Every decision is kept as a private training example

The review queue, at work

When the AI isn’t sure, mail waits here with its reasoning shown. You decide — and every choice teaches the next read.

Reads like a meeting request, but this sender has never appeared in Meetings before — Personal is also plausible.

Built on principles, not promises

What mailbud will never do

It never sends, replies or forwards on your behalf. mailbud reads and files — that's the whole job.

Your mail is read only to classify it. It is never used to train an AI model, and never leaves your tenant's scope.
No training on your dataPrivate by design
No brittle rules to maintain. Describe a category once in plain language and let it adapt as your mail changes.

Questions, answered

Does mailbud send or reply to emails for me?

No. mailbud only reads incoming mail and files it into folders. It never sends, replies to, or forwards anything on your behalf.

Do I have to build rules or filters?

No. You describe each category in plain language — for example “client questions about their project”. The AI reads that description and your past decisions to classify new mail.

Will my email be used to train AI models?

Never. Your mail is read only to classify it in the moment. It is not used to train any model, and your training examples stay private to your account.

Which email does it work with?

mailbud works with Outlook and Microsoft 365 mailboxes through the official Microsoft Graph API. You sign in with your Microsoft account.

What does it cost?

14 days free. After that, the Pro plan is €14.99 per month, billed via Stripe (card, iDEAL or SEPA) and cancellable any time.

What happens to mail the AI isn't sure about?

It goes to a review queue with the reasoning shown, instead of being filed in the wrong place. You approve or reassign it, and that choice improves future filing.
