Outlook add-in for project-based work

Every email with the right project. Detected automatically, filed in one click.

MailboxPilot recognizes the project from numbers, keywords and known contacts, adds the project header to the subject and archives the message as an EML file in your project folders – attachments, Outlook color categories and consistent file naming included.

For agencies, engineering and design offices, law firms, IT and construction projects. Works in Outlook for Windows, the new Outlook and Outlook on the web.

What it does

What MailboxPilot takes off your plate

Seven chores that eat time in every project mailbox – ordered by the moment MailboxPilot steps in.

On arrivalProject detection

Project number in the subject, keywords, known contacts and domains – MailboxPilot suggests the project with a confidence score and reasons, and remembers conversations.

While writingProject subject header

While composing, MailboxPilot adds the project header – e.g. [26-014 Website Relaunch] – following your rules, including replies and forwards.

On clickOne-click filing

Save an email or a whole conversation as EML with attachments in the project folder – named by your template, e.g. 260731_0912_Approval_Design_Draft.eml.

In the backgroundAutomatic inbox filing

Optionally, MailboxPilot files unambiguous matches on its own – enabled per project, with an adjustable confidence threshold and a full log.

After sendingSent-mail filing

Sent emails are recognized through your Microsoft account and assigned to the project folder – even when they were written on your phone.

In the mailboxOutlook color categories

Project and content category directly on the message, project always first – for sorting and search across all of Outlook.

On requestExclusions

Newsletters and system mail are recognized by their typical traits and left alone; specific senders, domains or conversations can be excluded explicitly.

Setup

Ready in three steps

No servers, no IT project: install the add-in and get going. A guided checklist and an interactive demo walk you through the start.

Step 1

Create a project

Project number and name are enough. Keywords, contacts and domains sharpen the detection.

Step 2

Connect a folder

Pick one folder per project on your drive – local or on the company network.

Step 3

File emails

Confirm the suggestion or use the quick actions in the ribbon. MailboxPilot spots duplicates by itself.

Artificial intelligence

AI that works for you – not the other way around

Two separate building blocks, clearly labeled: recognition learns locally on your device. The writing assistant uses the cloud – only when you call it.

Local, on your device

Learning categories

MailboxPilot classifies emails into categories like quote, approval, invoice or meeting notes – and learns from your corrections and your archive. Custom categories included.

  • Your own detection keywords per category
  • One-click corrections, effective immediately
  • No cloud account needed, nothing leaves the device
Cloud, on demand

AI writing assistant

Draft, revise, shorten, translate or suggest replies – with project context and without invented commitments or dates.

  • Quick actions: More formal · Friendlier · Shorten · Proofread · DE ↔ EN
  • Replaces only the draft – signature and quoted history stay
  • No text goes out unseen

In comparison

Why not simply carry on as before?

Most teams choose between three routes: filing by hand, connecting a document management system, or archiving everything to a cloud service. Here is where MailboxPilot fits in – and where it doesn't.

  MailboxPilot Filing by hand DMS integration Cloud archiving
Setup 2 minutes, no server, no training none IT project with server, roles and onboarding Account plus mailbox connection
Where emails live In your folders, as open EML files In your folders In the vendor's system, export required With the vendor
Project assignment Detected automatically, with score and reasons You remember it Usually manual folder picking Usually none at all
Effort per email One click – or none Save, rename, sort Several clicks plus metadata None, but no structure either
Emails you send yourself Including from your phone, via Microsoft 365 manually only depends on the product usually included
Still usable without the product Yes – files and Outlook categories remain Yes No, not without an export No
AI while writing Included, on demand only rarely rarely
Audit-proof long-term archiving No – a DMS is the right tool for that No Yes partly

The columns describe typical properties of each category, not specific products – individual vendors' features and prices change continuously.

01

Detection that explains itself

Every suggestion comes with a confidence score and a reason – "project number in the subject", "sender belongs to this project". You see why something is proposed instead of having to trust a black box.

Corrections take effect immediately and stick: what you change by hand is never overwritten by the automation.

02

Your archive stays yours

Messages are stored as EML – an open format any mail client can open – in folders you choose. No upload, no database, no vendor lock-in.

The honest test: remove MailboxPilot tomorrow and your entire project archive stays fully readable. Even the Outlook color categories remain in place.

03

Including what you write yourself

Most filing tools take care of the inbox. Yet half of a project's correspondence consists of your own replies – often written on a phone somewhere on site.

MailboxPilot recognizes sent messages through your Microsoft 365 account and assigns them, no matter which device they came from.

04

Not an IT project

No server installation, no database, no migration, no training. Add a manifest to Outlook, create a project, get going – optionally rolled out to the whole team through the admin center.

That makes MailboxPilot worthwhile even for a five-person office that would never consider a document management system.

FAQ

Frequently asked questions

Where do my emails and files live?

On your own drives – local or on the company network. MailboxPilot writes EML files and attachments into the folders you pick per project. There is no file upload to a MailboxPilot cloud.

Which Outlook versions does MailboxPilot support?

Classic Outlook for Windows, the new Outlook and Outlook on the web. On the Mac, direct folder filing isn't technically available; there MailboxPilot delivers the filing as a ZIP download.

Do I need my IT department to install it?

Not for a single seat – the add-in is added to Outlook through a manifest file. For teams, your IT distributes the add-in centrally to all mailboxes through the Microsoft 365 admin center.

What happens after the trial?

All features remain free for one project of your choice. Your existing archive stays fully intact. Professional unlocks unlimited projects.

How does MailboxPilot handle privacy?

Project detection and category learning run locally on your device. The optional writing assistant sends the email content to an Azure OpenAI instance in the EU to generate text and stores nothing. Details are in the privacy policy (German).

Which industries is MailboxPilot for?

Anyone who organizes work in projects: agencies, engineering and design offices, law firms, consultancies, IT and construction projects. MailboxPilot only knows projects with a number, a name, keywords and a folder – what kind of project sits behind that is up to you.

Can I use MailboxPilot in my language?

The interface is fully bilingual and follows your Outlook display language: German for German-language locales, English for everything else.

Try MailboxPilot for 7 days with the full feature set – and keep a clean project archive either way.
