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.

Needs review

Shortlist when you need Swiss-hosted professional email with custom domains, IMAP/CalDAV, suite bundling (kSuite), and operator-owned DCs. Skip when zero-access client-side E2EE or full self-host is mandatory—consider Proton Mail (E2EE) or a self-hosted stack 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.

Infomaniak kMail

Custom-domain mail with IMAP, CalDAV and CardDAV
Host name@your-domain addresses with standard IMAP/SMTP plus CalDAV/CardDAV so Thunderbird, Apple Mail, Outlook and other clients stay usable. Paid kSuite/Mail Service tiers add multi-mailbox management, aliases/categories, signatures and team admin; free my kSuite is limited to one address without aliases.
One-click send-time encryption (OpenPGP / ECC / AES)
Optional encryption at send uses OpenPGP, ECC and AES-256-GCM; Infomaniak-to-Infomaniak is automatic after auth, while external recipients often open a password-protected secure page. Private keys stay on Infomaniak infrastructure—useful for sensitive sends, but not zero-access client-side E2EE with user-held keys.
Open-source Infomaniak Mail mobile clients
Official iOS and Android mail apps are published on GitHub under GPL-3.0 for local inspection and contribution. The hosted mail backend remains Infomaniak SaaS only—there is no supported self-hosted server stack for kMail.
Swiss dual-DC backups, SPF/DKIM/DMARC and antivirus
Mailboxes are backed up across Swiss data centres with vendor-stated restore windows around 30 days; anti-spam/antivirus plus domain authentication (SPF, DKIM, DMARC) are standard. Availability claims (e.g. high uptime for essential services) should be checked against the current SLA for your plan.
Sovereign AI assist (Euria) inside the mailbox
In-product AI can help draft, correct, translate and process mail context; Infomaniak states messages sent to its AI are processed in Switzerland and not stored for other purposes. Treat AI features as operator-side processing of content you choose to submit—not as end-to-end private AI.

Assurance & compliance: Combell E-mail vs Infomaniak kMail
Assurance & compliance	Combell E-mail	Infomaniak kMail
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 Bug bounty and ISO ISMS claimed; no public independent no-logs audit of mailbox content found. Encryption is optional and keys remain with Infomaniak.
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.	Vendor claimed Vendor publishes ISO 27001:2022 certificate (certified since 2018 per certifications page); downloadable PDF and SoA references.
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 Not listed among published certifications (ISO 27001/9001/14001/50001, B Corp, Swiss labels).
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 Swiss entity; GDPR and Swiss FADP commitments on legal pages; DPO listed; Swiss hosting of service data claimed.
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 Swiss Infomaniak Network SA, no known US parent, own Swiss DCs for mail—not a claimed clean bill. Account payments via partners such as PayPal/Checkout (US-group) per confidentiality policy. Indicative 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 Downloadable DPA linked from trust centre (Data_Processing_Agreement (DPA).pdf).
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 Euria AI assist exists inside mail; product is primarily email/hosting, not an AI-system vendor offering.

Considerations & known limitations: Combell E-mail vs Infomaniak kMail
Considerations & known limitations	Combell E-mail	Infomaniak kMail
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
Encryption is not zero-access by default	Not listed	Medium Optional send encryption keeps private keys on Infomaniak infrastructure. Operators with warrant or insider access to the platform may still access unencrypted stored mail. Practical impact: do not treat kMail as a zero-knowledge vault for all messages.
SaaS-only mail backend	Not listed	Low No official self-host for the mail service; exit means IMAP export/migration. OSS clients do not equal portable server stack.
Free tier residency and feature caps	Not listed	Low my kSuite requires OECD residency and phone verification; no aliases, limited storage, enforced free signature. Unsuitable as free global professional mail.
Limited public mail-path subprocessor table	Not listed	Low Hosting is own Swiss DCs per vendor docs; confidentiality policy lists payment and marketing-class third parties. Procurement should request a current subprocessor list for mailbox content paths.
No HDS health-hosting cert	Not listed	Medium Vendor FAQ states French HDS certification is not planned—material for French health-sector workloads.

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.

Infomaniak kMail

Best fit when

SMEs and associations wanting Swiss-hosted name@domain email with standard IMAP clients
Teams that prefer an integrated kSuite workspace (mail + drive + meet) under one Swiss operator
Orgs that need a published B2B DPA, dual-site Swiss backups, and SPF/DKIM/DMARC on domains
Buyers who value open-source mobile clients even if the mail backend is SaaS-only
Individuals in OECD countries open to free my kSuite with known feature and residency limits

Poor fit when

Requirements for default zero-access E2EE with user-held keys on every message
Need to self-host the mail server stack (kMail is SaaS-only)
French HDS health-data hosting (vendor states HDS certification is not planned)
Free-tier signup outside OECD residency / without mobile verification
Very large estates that need more than kSuite's published per-offer user ceiling without a custom deal

Consider instead when

When: You need zero-access end-to-end encryption as the default mail model
Consider: Proton Mail
Different trust model: client-side E2EE vs Infomaniak operator-held keys for optional encryption
When: You want European hosted mail with a different encryption or non-profit posture
Consider: Mailfence or Posteo
Compare encryption UX, storage model, and commercial terms on each vendor site
When: You need full control of the MTA and storage stack
Consider: Self-hosted mail (e.g. mailcow/Stalwart) or a host that publishes server software
Infomaniak mobile apps are OSS; the hosted service is not self-hostable

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?

Infomaniak kMail

Request the current subprocessor list scoped to Infomaniak Mail mailbox content (not only account billing).
Confirm whether optional encryption is fully rolled out on mobile apps for your required clients.
Validate seat ceilings, SLA, and restore RPO/RTO against your RTO targets for the chosen kSuite/Mail plan.
For regulated sectors: map FADP/GDPR DPA clauses and any sector addenda (FINMA mapping exists; HDS does not).
