Combell E-mail

Belgium· Email Services

Needs review

Shortlist when you need Benelux domain mail with phone-first support, Hosted Exchange on Combell infrastructure, or Microsoft 365 sold with local onboarding from a Belgian host. Skip when you need zero-access / E2EE mail or a vendor that never routes collaboration data through Microsoft — consider Mailfence, Proton Mail, or Tuta instead.

RAIDBOXES Emails

Germany· Email Services

Needs review

Shortlist when you already (or will) host the domain and WordPress stack at RAIDBOXES and need practical multi-mailbox domain email under a German operator with an online DPA. Skip when you need multi-domain density, default E2EE, or email fully independent of a hoster—consider Migadu, Tuta, Posteo, or mailbox.org instead.

Combell E-mail

Domain Basic mailboxes (IMAP/POP3/SMTP)
Create addresses on your own domain with multi-device sync, client compatibility (Outlook, Apple Mail, mobile), and browser webmail. Published storage tiers include 5 GB, 50 GB, and 100 GB Basic plans with spam/antivirus filtering and daily mailbox backups. Suited to SMEs that need professional mail without Exchange collaboration features.
Hosted Exchange with calendars and push
Exchange mailboxes add shared calendars, task lists, meeting-room booking, and direct push notifications, with free transfer help for existing Exchange setups. Combell states Exchange mail runs in Belgium and Netherlands data centres. Choose this when teams need Outlook-style groupware without the full Microsoft 365 app suite.
Microsoft 365 reseller with local setup
Business and Enterprise Microsoft 365 packages combine Exchange mail with Office apps, OneDrive, Teams, and related Microsoft cloud services. Combell differentiates with DNS/mailbox configuration service and 24/7 support in local languages rather than Microsoft-only helpdesks. Mailbox and file data on this path are processed by Microsoft, not only on Combell hardware.
Spam filtering, antivirus, and daily backups
Basic and Exchange product pages include automated spam and virus scanning plus daily mailbox backups for restore after accidental deletion. Microsoft 365 customers can add a separate Combell Microsoft 365 backup product for more frequent cloud backups of mail and files. Local client backups are still recommended for dual protection.
SMTP relay and Flexmail marketing path
A dedicated mail-server / SMTP relay product targets higher-volume sending with plan-based monthly send limits and optional dedicated IP, aimed at newsletters and app transactional mail that would hit shared-mailbox limits. New mailbox customers are offered Flexmail e-mail marketing trial packages via the sister brand in the team.blue group.
24/7 multilingual Benelux support
Combell markets round-the-clock support by phone (toll-free lines advertised), chat, and e-mail in local languages, including weekends and holidays. The company claims to have been the first Belgian hoster with 24/7 support (from 2000). This is a core reason Benelux SMEs pick Combell over pure self-serve global suites.

RAIDBOXES Emails

Mail Hosting 2.0 on RAIDBOXES infrastructure
IMAP/SMTP mailboxes on dedicated hostnames (mail-rb.securemail.pro / smtp-rb.securemail.pro) after the move off the prior mailbox.org cooperation. Vendor claims German data-centre locations and triple-redundant mail servers. Best for teams that want domain mail under the same German WordPress host rather than a separate privacy-mail brand.
Multi-mailbox plans with aliases, forwards, and catch-all
Tiered plans allocate a fixed number of mailboxes and a shared storage pool, plus per-mailbox alias and forwarding quotas, autoresponders, and catch-all (requires a dedicated catch-all mailbox). One connected domain per plan—confirm multi-domain needs before shortlisting.
Spam/virus filters, TLS, optional PGP, ad-free inboxes
All plans include spam and virus filtering, SSL/TLS for transfer, a blacklist checker, webmail, and ad-free inboxes. PGP is optional rather than default end-to-end encryption for every message—teams that need mandatory E2EE workflows should evaluate Tuta or a full mailbox.org stack instead.
Dashboard-adjacent domain and WordPress ops
Mailboxes are ordered from the RAIDBOXES dashboard and are intended to sit next to WordPress hosting and domain management. New RAIDBOXES mailboxes require the domain to be hosted with RAIDBOXES; legacy mailbox.org-linked domains follow a separate migration path documented in the help centre.
Online B2B DPA and German operator
Raidboxes GmbH (Münster) offers an online data processing agreement (AV contract) with technical-organisational measures. Useful for agencies that already sign a DPA for WordPress hosting and want the same counterparty for domain email—still review TOMs and subprocessor scope for mailbox vs platform tooling.

Assurance & compliance: Combell E-mail vs RAIDBOXES Emails
Assurance & compliance	Combell E-mail	RAIDBOXES Emails
Independent security / no-logs audit	Not found No public independent no-logs or mailbox-content audit found; ISO certificates are management-system certs, not no-logs proofs.	Not found No public third-party security or no-logs audit report found for RAIDBOXES Emails on primary pages.
ISO 27001	Vendor claimed Vendor states first Belgian hoster certified in 2011; certificate PDF linked on ISO page; scope includes hosting and related services. Re-verify current certificate in procurement.	Not found No company-wide ISO 27001 certificate for Raidboxes GmbH found on product/security pages; AWS region ISO mentions are not RAIDBOXES certs.
ISO 27701 (privacy information management)	Vendor claimed Vendor claims first Benelux hoster (2021); scope text includes e-mail and office tools. Certificate PDF linked on site.	Not listed
ISO 9001	Vendor claimed Vendor claims certification since 2007; certificate PDF linked; scope includes e-mail & tools among other services.	Not listed
SOC 2 / SOC 3	Not found No public SOC 2/3 report located on Combell marketing/trust pages during research.	Not found No public SOC 2/3 report located for RAIDBOXES Emails.
GDPR / EU data protection	Vendor claimed Belgian EU entity; detailed privacy policy referencing GDPR; ISO 27701 claimed for privacy management. Confirm DPA and processing roles for your use case.	Vendor claimed German controller (Raidboxes GmbH); product claims DE server locations and GDPR-aligned deletion; online DPA available. Confirm active mail stack vs privacy-policy mailbox.org listing.
US CLOUD Act exposure (indicative)	Partial EuropeanStack assessment: no known US parent of Combell nv, but Microsoft 365 SKUs use Microsoft (US-parented) as cloud processor; public subprocessor list missing; privacy policy contemplates non-EU manufacturers with SCCs for some products. Basic/Hosted Exchange on Benelux DCs is a lower-exposure path than Microsoft 365. Not legal advice.	Partial EU/German entity, no known US parent (team.blue BE group). Medium residual exposure via US-group platform subprocessors (AWS/DigitalOcean for online offer hosting; Intercom, Chargebee, Google tooling, Mailgun, etc.). Mail content path claimed DE-only. Not legal advice.
Data processing agreement (B2B)	Not found No self-serve public DPA download found. Privacy policy describes processor contracts with sub-contractors; contact Data Protection Team (data.protection@combellgroup.com) to request current DPA and subprocessor list.	Vendor claimed Online AV/DPA flow at raidboxes.io/en/dpa/ and DocuSign TOM path documented in help centre.
EU AI Act	Not applicable Core product is email hosting; optional Microsoft Copilot add-on is Microsoft AI — evaluate under Microsoft terms if purchased, not as a Combell-native AI system.	Not applicable Domain email hosting product, not an AI system offering.
B Corp certification	Not listed	Vendor claimed Raidboxes GmbH listed as Certified B Corporation on B Lab directory; impact certification, not an information-security audit.

Considerations & known limitations: Combell E-mail vs RAIDBOXES Emails
Considerations & known limitations	Combell E-mail	RAIDBOXES Emails
Microsoft 365 path uses Microsoft cloud	High Choosing Microsoft 365 via Combell does not keep mailbox/file data solely on Belgian Combell servers. Microsoft remains the cloud provider for those tenants; CLOUD Act and transfer diligence must treat Microsoft, not only Combell.	Not listed
No public subprocessor list	Medium Privacy policy confirms third-party processors and group sharing but does not publish a named register. Buyers must request the current list (including Flexmail, Microsoft if applicable, and team.blue affiliates) before relying on residency claims.	Not listed
Not end-to-end encrypted mail	Medium Provider-side spam filtering and backups imply conventional hosted mail architecture. Unsuitable where zero-access encryption is a hard requirement.	Not listed
ISO claims not independently re-verified here	Low ISO 9001/27001/27701 are vendor-published with PDF certificates. This evaluation marks them claimed; procurement should check validity dates and scope against the actual email services purchased.	Not listed
PE-backed group ownership	Low team.blue has major PE investors (Hg and reported co-investors). This is European PE structure, not a US Big Tech parent, but ownership can change; track change-of-control clauses in contracts if sovereignty is critical.	Not listed
Domain must be hosted at RAIDBOXES	Not listed	Medium New mailboxes require the domain on RAIDBOXES. That is convenient for WP customers and a lock-in factor if you only wanted independent mail.
One connected domain per plan	Not listed	Medium Multi-domain operators need multiple plans or another provider; not a Migadu-style multi-domain account model.
PGP optional, not default E2EE	Not listed	Medium Threat models that assume provider-side unreadability by default are a better fit for Tuta or similar products.
US-group platform subprocessors	Not listed	Medium Privacy policy discloses AWS EMEA, DigitalOcean, Intercom, Chargebee, Google tools, Mailgun, and others for website/support/billing/marketing—even while email marketing claims German mail servers. Scope diligence to mailbox vs platform data paths.
Privacy policy may lag Mail Hosting 2.0	Not listed	Low §Email box still lists mailbox.org/Heinlein while marketing claims first-party hosting—confirm live stack and subprocessor annex for your contract.
No public ISO/SOC/mail audit	Not listed	Medium B Corp is not a security certification. Enterprise security questionnaires may need NDA materials or alternative providers with published audits.

Fit

Combell E-mail

Best fit when

Benelux SMEs that want professional domain addresses with IMAP/POP or Exchange and a real phone helpdesk
Teams already buying domains or web hosting from Combell / team.blue and consolidating vendors
Organisations that need Hosted Exchange calendars and push without standing up their own mail servers
Buyers who want Microsoft 365 with local DNS/mailbox configuration and 24/7 Dutch/French/English support
Senders who need an SMTP relay or Flexmail path alongside domain mailboxes

Poor fit when

Requirements for end-to-end encrypted or zero-access email (provider cannot read content)
Need for open-source self-hosted mail only (Combell is hosted SaaS, not a self-host product)
Hard ban on any Microsoft-class processor when the org still wants full Office cloud collaboration
Procurement that requires a public subprocessor register before first contact (list not published online)
Teams seeking free unlimited consumer mail rather than paid professional mailboxes

Consider instead when

When: You need Belgian or EU end-to-end encrypted mail with OpenPGP / zero-access positioning
Consider: Mailfence (Belgium) or Proton Mail
Combell is classic hosting mail with spam filters and backups, not an E2EE privacy suite.
When: You want privacy-focused paid mail without Microsoft suite lock-in and are fine outside Benelux support culture
Consider: Posteo, Tuta, Soverin, or Runbox
Stronger anti-tracking or encryption narratives; thinner local Belgian phone support than Combell.
When: You only need Microsoft 365 and do not value a Benelux reseller for setup/support
Consider: Microsoft 365 direct (or Google Workspace if you prefer Google)
Combell does not remove Microsoft as processor; direct purchase may be simpler for pure Microsoft estates.

RAIDBOXES Emails

Best fit when

WordPress agencies and freelancers standardising on RAIDBOXES for sites, domains, and mail admin
SMEs wanting professional multi-mailbox domain email with standard IMAP clients—not a full Google/Microsoft suite
Teams that need catch-all, aliases, forwards, autoresponders, and ad-free inboxes on one domain
Buyers who require a German legal counterparty and an online B2B DPA for processor agreements
Operators migrating off legacy mailbox.org-linked RAIDBOXES mail toward first-party Mail Hosting 2.0

Poor fit when

Multi-domain mail estates that need many domains under one contract (one connected domain per plan)
Policies requiring default end-to-end encryption for all mail (PGP is optional only)
Buyers who refuse any coupling between mailbox service and domain/WordPress hosting
Teams seeking a full office suite (Drive, collaborative docs, built-in video) rather than domain mail
Procurement that demands public ISO 27001/SOC 2 or independent no-logs audit reports for the mail product

Consider instead when

When: You need multi-domain, usage-based professional mail without WordPress host lock-in
Consider: Migadu
Swiss-operated, standards-based hosting priced by quotas rather than per-domain WordPress adjacency
When: You need default E2EE and a privacy-first client model
Consider: Tuta
Different threat model; less IMAP flexibility than RAIDBOXES
When: You want privacy-oriented German personal/business mail without hosting coupling
Consider: Posteo or mailbox (formerly mailbox.org)
mailbox is also the former RAIDBOXES mail partner and a deeper digital-workplace option
When: You need Google/Microsoft suite collaboration, not just domain mailboxes
Consider: Google Workspace or Microsoft 365
US Big Tech residency and CLOUD Act profile differ sharply—use only if suite features dominate

Open questions for due diligence

Combell E-mail

Will Combell provide a signed DPA and a current named subprocessor list for Basic vs Hosted Exchange vs Microsoft 365 SKUs?
For Basic and Hosted Exchange, are all mailbox stores, backups, and anti-spam engines restricted to Belgium/Netherlands with no US-group subprocessors?
What Microsoft data residency / EU Data Boundary options are available on Combell-sold Microsoft 365 tenants?
Can independent auditors receive ISO certificate numbers, scopes, and any penetration-test summaries under NDA?
How is Flexmail (and other sister brands) contractually separated when mailbox customers enable marketing tools?

RAIDBOXES Emails

For a new Mail Hosting 2.0 mailbox, is mailbox.org/Heinlein still a subprocessor for mailbox content, or only a legacy path?
Which German data-centre operators and exact regions host mail storage and backups (primary + DR)?
Does the standard DPA/TOM annex explicitly cover email hosting subprocessors separately from WordPress hosting?
What are published RPO/RTO and restore procedures for mailbox backups?
Are there any upcoming multi-domain plan options or reseller mail SKUs?
