A complete walk-through of every feature, for anyone at your company using app.mailbroom.app.
Getting started
MailBroom is licensed per company domain, not per person — there's nothing to invite.
Sized to headcount, billed monthly via Stripe — see the plans table below.
Using the same work account they already use for Outlook and Teams. Once your company's plan is active, anyone with a matching email domain joins automatically the first time they sign in.
Sign-in goes through Microsoft Entra ID directly. MailBroom only ever receives a scoped, revocable Graph access token — revoke it any time from your Microsoft admin settings.
Overview
Your inbox at a glance, and the entry point to the three cleanup tools.
Total emails, storage used, and how many are ready to sweep from your last scan. Tap Re-scan any time — MailBroom also quietly checks for new mail in the background.
Storage freed, emails deleted, unsubscribed, organised, time saved, a Potential Speed score, live Sync Status, and CO₂ saved with award tiers from Seedling up to Earth Hero — all real, lifetime totals tied to your account.
Getting Started
New to the three tools? This order gets you the biggest win first, then keeps the inbox clean going forward.
Start here for the immediate win — find the largest, oldest attachments and senders actually taking up space, and clear them by age bracket or by domain.
Then handle the ongoing flow — clear out daily newsletters and notifications sender by sender, or in bulk.
Use this as needed for anything specific — a targeted lookup, a compliance request, or a one-off cleanup task, rather than as a first pass.
Tool
Bulk-clear newsletters, notifications, and anything else worth clearing — one sender at a time, or in bulk.
One sender at a time, largest first — swipe through and decide.
Select any number of senders and apply one action to all of them at once.
Tool
Find what's actually taking up space — two ways to look at the same mailbox.
Senders bucketed by how old their emails are, with a High/Medium/Low confidence read on how safe each is to clear.
Senders grouped by company — with D/U/K/O actions at the domain level, so one click clears an entire domain's worth of senders at once.
| Bracket | What it usually holds |
|---|---|
| 10+ Years | The oldest mail in the account — almost always safe to clear |
| 5–10 Years | Still very old, rarely needed |
| 3–5 Years | Worth a glance before clearing in bulk |
| 1–3 Years | Recent enough that individual review pays off |
| Under 1 Year | Current — review carefully |
Tool
Find a specific email fast, then act on the results in bulk.
Sender, subject, keywords, has attachment, date range, read/unread, flagged — combine as many as needed.
Select matching emails across senders and delete or move them to a folder in one action.
Plans
One flat monthly fee per company domain, banded by seat count — not billed per person.

Data
What's stored, and — just as importantly — what isn't.
Your email and name, your company's licence status, and aggregate usage counters (emails cleaned, storage freed, CO₂ saved).
Email content is fetched live from Graph, never written to a database. Also never stored: your Microsoft password, or payment card details.
