Clean Email is a real, well-established tool for bulk-organising and unsubscribing from unwanted email, and it genuinely competes with MailBroom on the mechanics of cleanup. If you're an IT admin comparing the two for a company running Microsoft 365, though, the honest answer is: they're built for different buyers.
Clean Email is built around personal account bundles — buy access for 1, 5, or 10 accounts and share it with people you know, like family.MailBroom for Business is licensed once per organisation, with every employee on the company's Microsoft domain getting access automatically through Microsoft SSO. That single difference shapes almost everything else about how each tool fits — or doesn't — into a company's Microsoft 365 tenant.
Clean Email's own pricing page frames its multi-account plans around sharing with people you know personally — buy 5 or 10 accounts and share them with friends and family. It does support company/business use, with employees at thousands of companies among its users, but the published buying model is account bundles, not an organisation-wide licence.
MailBroom for Business is licensed per organisation, not per person. An IT admin subscribes once, signs in via Microsoft SSO, and every employee with a matching company email address gets automatic access — no invite list, no separate account for each person to manage, no shared credentials.
A common IT admin need is cleaning up shared inboxes — info@, sales@, or a departing colleague's delegated mailbox — not just each employee's own account. We couldn't find any published documentation from Clean Email addressing shared or delegated mailbox support specifically.
MailBroom explicitly supports this: once an org admin enables it, a shared or delegated mailbox can be connected and cleaned the same way as a personal one, provided the connecting user has Exchange Full Access on that mailbox.
| MailBroom for Business | Clean Email | |
|---|---|---|
| Licensing model | Per organisation, by seat band | Per account bundle (1 / 5 / 10) |
| Deployment | One Microsoft SSO sign-in covers the domain | Each account signed in separately |
| Shared/delegated mailboxes | Explicitly supported | Not documented publicly |
| Published company pricing | Yes — flat monthly by seat band | No official org pricing — per-account bundles from ~€11.99/mo (per TheBusinessDive) |
| Team/collaboration fit | Built for company-wide use | Scored 1/5 by TheBusinessDive — "designed for individuals, not teams" |
| Email providers supported | Microsoft 365 / Exchange Online (company-wide); other providers via the separate MailBroom for iOS app | Gmail, Yahoo, AOL, and more, all in one product |
That last row is less of a gap than it looks: Microsoft 365/Exchange Online is what the large majority of businesses actually run, and MailBroom's Microsoft-only focus for Business is what makes the one-click, tenant-wide SSO deployment possible in the first place. For an organisation on genuinely mixed providers, Clean Email covers that in a single product — MailBroom's equivalent coverage exists too, just split across two products (Business for M365 companies, iOS for everything else via IMAP), not one.
MailBroom for Business connects via Microsoft Entra ID sign-in (Microsoft SSO) and the Microsoft Graph API. It never sees or stores a password — it receives a scoped, revocable access token limited to exactly what mailbox cleanup requires, and an org admin can revoke that access instantly from the organisation's own Microsoft admin settings, independent of MailBroom entirely.
Clean Email's own privacy policy states it "may have to store authorisation credentials and related information" for some third-party mail providers — meaning, for at least some connections, it may retain account credentials rather than exchange them for a scoped, revocable token the way OAuth does. For Gmail specifically, Clean Email says it only reads message metadata and headers, never message bodies — a reasonable scope limit, but it's a Gmail-specific commitment, not a blanket statement about every provider it connects to. Clean Email doesn't publish SOC2 or ISO27001 certification.
| Feature | MailBroom for Business | Clean Email |
|---|---|---|
| Bulk delete / unsubscribe by sender | ✓ | ✓ |
| Storage cleanup by age or domain | ✓ | Partial — organising focus, not storage-targeted |
| Shared/delegated mailbox support | ✓ | Not published |
| Company-wide SSO licensing | ✓ | ✗ — per-account bundles |
| Published per-org pricing | ✓ | ✗ — quote-only |
| Works within retention policy / legal hold | ✓ | Not published |
| Non-Microsoft email providers (Gmail, Yahoo, etc.) | ✗ — via MailBroom for iOS instead | ✓ — in one product |
| Never stores account credentials | ✓ — OAuth token only | Not for all providers, per own policy |
"Not published" means we found no public documentation either way — not that the feature is absent.
For bulk organising and unsubscribing, yes — the core cleanup mechanics are comparable. The difference is who each is built for: Clean Email's pricing is structured around buying a bundle of accounts (1, 5, or 10) to share with people you know personally, like family. MailBroom is licensed once per organisation, with every employee on the company's Microsoft domain getting automatic access via Microsoft SSO — no shared logins, no per-person account purchase.
We found no published documentation on shared or delegated mailbox support for Clean Email. MailBroom explicitly supports this — an admin can enable access to a shared mailbox like info@ or sales@, or a colleague's delegated mailbox, the same way as a personal one, once that's turned on for the organisation.
Clean Email doesn't publish per-organisation pricing on its own site — its plans page is structured around personal account bundles, with a 'contact us for a quote' path for bulk/organisational needs. Independent review site TheBusinessDive lists Clean Email's account-bundle pricing at roughly €11.99/month for 1 account, €23.99/month for 5, and €35.99/month for 10, with monthly billing — and that same review scores its team/collaboration fit just 1 out of 5, noting it 'was designed for individuals, not teams.' MailBroom publishes flat monthly pricing by seat band (1–5, 6–10, 11–25, 26–50, 51–100 seats) built specifically for company-wide use, with custom quoting only above 100 seats.
Within one product, yes: Clean Email connects to Gmail, Yahoo, AOL, and other providers as well as Microsoft 365. MailBroom for Business is deliberately M365/Exchange Online-only — that focus is what lets it plug directly into Microsoft Graph API and Entra ID for one-click company-wide SSO deployment, and M365/Exchange Online is what the large majority of businesses actually run, so this is rarely a real gap in practice. If your organisation genuinely needs other providers too, the wider MailBroom family covers that ground via a second product: MailBroom for iOS connects over IMAP to almost any mail server, including Gmail and Yahoo — just as a personal-inbox app rather than a company-wide deployment.
