Needs review
Shortlist Cloud Mail when you need Italian-operated, managed domain email with Plesk, Roundcube, CalDAV/CardDAV, and pre-delivery antispam on Seeweb infrastructure. Skip when you need end-to-end encrypted / zero-access mail (consider Proton Mail or Tuta) or a full Workspace/365 productivity suite (Google Workspace / Microsoft 365).
Switzerland· Email Services
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.

Plesk domain mail admin (mailboxes, aliases, forwards)
One admin account manages mailboxes, passwords, aliases, forwards, and auto-replies in Plesk, with quota/usage visibility per account. Suited to SMEs and resellers who want classic hosting-style control without running their own MTA.
Roundcube webmail + IMAP/POP3/SMTP on mail.truemail.it
Users access mail via Roundcube (webmail.truemail.it) or standard clients. Docs publish IMAP/POP3/SMTP endpoints with STARTTLS and SSL port options for Outlook, Thunderbird, Apple Mail, and mobile. CalDAV and CardDAV cover calendar and contacts sync.
Managed pre-delivery antispam/antivirus (no default spam folder)
Centralized filters check sender IP/domain behaviour and content before the message is accepted. Rejected spam is returned to the sender rather than filed in a default spam mailbox; false positives are handled via ticket or report@postmaster.seeweb.it. Accuracy is not claimed to be 100%.
Daily off-site backups (IBM Spectrum Protect, 30-day history)
Incremental daily backups run to a remote Seeweb data center using IBM Spectrum Protect software. Deleted mail can be requested for recovery within about 30 days; restores recover the backed-up set rather than individual selected messages, so IMAP is recommended.
Scalable domain packs + WhiteLabel resale
Plans scale from small 5 GB / 5-mailbox packs through large multi-hundred-GB packs with matching mailbox counts (up to on the order of 1,280 mailboxes). A domain is required at activation. WhiteLabel supports partners who resell branded mail on Seeweb’s managed stack.
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 | Cloud Mail | Infomaniak kMail |
|---|---|---|
| Independent security / no-logs audit | Not found No public third-party no-logs or mail-specific penetration audit PDF found for Cloud Mail; ISO ISMS certs are separate. | 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 certifications page: ISO/IEC 27001:2022, scope includes mail services; AXE REGISTER cert IT18-27702D (listed valid until 28 Nov 2027). Not independently re-verified in a public registry by this draft. | Vendor claimed Vendor publishes ISO 27001:2022 certificate (certified since 2018 per certifications page); downloadable PDF and SoA references. |
| ISO 27017 / 27018 (cloud) | Vendor claimed Published on certifications page as appendices to the ISO 27001 certificate; mail services in process scope. | Not listed |

| GDPR / EU data protection | Vendor claimed Italian controller entity, named DPO, privacy policy under GDPR; product marketed as GDPR-oriented; CISPE CoC adherence claimed. | Vendor claimed Swiss entity; GDPR and Swiss FADP commitments on legal pages; DPO listed; Swiss hosting of service data claimed. |
| CISPE Code of Conduct | Vendor claimed Certifications page: Seeweb cloud services adhere to CISPE; claims storage exclusively within European territories for covered services. | Not listed |
| US CLOUD Act exposure (indicative) | Partial EuropeanStack assessment: EU entity, DHH European group, no known US parent; public hosting story is Seeweb EU DCs and CISPE EU territory claim; backups on Seeweb off-site DCs (Spectrum Protect software, not described as US cloud mailbox SaaS). Residual gaps: no full public subprocessor list; antispam uses external reputation services not named on the docs page. 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 downloadable product DPA found on the marketing site; general conditions reference GDPR processing and the privacy notice. Request Art. 28 terms for mail content before go-live. | Vendor claimed Downloadable DPA linked from trust centre (Data_Processing_Agreement (DPA).pdf). |
| EU AI Act | Not applicable Cloud Mail is conventional email hosting, not an AI product. | Not applicable Euria AI assist exists inside mail; product is primarily email/hosting, not an AI-system vendor offering. |
| Considerations & known limitations | Cloud Mail | Infomaniak kMail |
|---|---|---|
| Subprocessor / antispam feed list not public | Medium Docs mention reputation services for antispam but do not publish a complete subprocessor table. Procurement should request the current list and transfer safeguards. | Not listed |
| Backup restore is set-based, not single-message | Low 30-day off-site history is useful, but restores recover the backed-up set; plan operational recovery expectations and prefer IMAP. | Not listed |
| Pre-delivery reject without default spam folder | Low Strong filtering can block legitimate senders; there is no user-visible spam quarantine by default—use tickets/reporting workflows. | Not listed |
| Not zero-access / E2EE-first mail | Medium Provider-managed conventional mail. Choose encrypted peers if the threat model assumes a compromised host provider. | Not listed |
| B2B DPA not prominent on site | Medium Treat contract/DPA negotiation as a gate for regulated workloads until Art. 28 terms and roles (controller/processor for mailbox content) are signed. | 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. |
