eclipso Mail Europe

Native OpenPGP and S/MIME in every plan
OpenPGP (RFC 4880/9580) key wizard and import work in webmail and apps, free from Freemail upward; S/MIME accepts user-supplied X.509 certificates for business clients. E2EE only applies when both sides use it—plain IMAP mail is not zero-access by default. Private keys for webmail PGP are held in the account under a passphrase for multi-device use.
Standard IMAP, POP3, SMTP plus CalDAV/CardDAV
Direct protocol access for Thunderbird, Outlook, Apple Mail, and mobile clients without a bridge product. Calendar and contacts sync via CalDAV/CardDAV; Premium and Business add WebDAV for the cloud drive. Suits teams that refuse locked-in web-only mail.
German-hosted suite: mail, drive, organizer
One account covers webmail, eclipso Drive file storage with link sharing, Media Center, calendar, address book, notes, and tasks. Vendor claims exclusive Germany data centres (privacy policy names Speedloc Datacenter, Görlitz). Storage and address limits scale by prepaid tariff; WebDAV and higher quotas need paid tiers.
Prepaid freemium with optional hybrid channels
Freemail signs up without credit card or phone number and is ad-supported; paid Connect/Premium/Business terms are prepaid and end automatically after a reminder. Credits enable SMS, fax, and hybrid physical post through named German gateways—useful for crafts and SMEs still on those channels.
Business domain and Art. 28 DPA on Business plan
Business includes a custom mail domain option, higher alias counts, daily send limits suitable for small campaigns, and an in-product Art. 28 GDPR DPA download per vendor docs. Not a full enterprise workspace: no public SCIM/SSO pack or multi-org admin model documented.

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: eclipso Mail Europe vs Infomaniak kMail
Assurance & compliance	eclipso Mail Europe	Infomaniak kMail
Independent security / no-logs audit	Not found No public third-party security or no-logs audit PDF located on official pages	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	Not found No ISO 27001 claim found on official security/about pages at research time	Vendor claimed Vendor publishes ISO 27001:2022 certificate (certified since 2018 per certifications page); downloadable PDF and SoA references.
SOC 2 / SOC 3	Not found No SOC 2/3 report referenced on official site	Not found Not listed among published certifications (ISO 27001/9001/14001/50001, B Corp, Swiss labels).
GDPR / EU data protection	Vendor claimed German controller, DPO contact, BayLDA authority, GDPR rights language in privacy policy; servers claimed in Germany	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 EU/DE owner-operated entity with DE hosting (Speedloc), but Stripe, PayPal, and Google reCAPTCHA/ad tooling introduce US-group processing paths for payment and website data. 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)	Vendor claimed Art. 28 DPA described as included and downloadable on Business plan; confirm for lower tiers	Vendor claimed Downloadable DPA linked from trust centre (Data_Processing_Agreement (DPA).pdf).
EU AI Act	Not applicable Email/cloud suite; not an AI system product	Not applicable Euria AI assist exists inside mail; product is primarily email/hosting, not an AI-system vendor offering.

Considerations & known limitations: eclipso Mail Europe vs Infomaniak kMail
Considerations & known limitations	eclipso Mail Europe	Infomaniak kMail
Not zero-access by default	Medium Without OpenPGP/S/MIME, mailbox content is accessible to the operator like traditional IMAP hosts. Webmail PGP private keys are stored in-account under a passphrase—review threat model vs pure local keys.	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.
US-group payment and site tooling	Medium Stripe, PayPal, Google reCAPTCHA, and documented ad partners process personal data outside pure DE mailbox hosting. Material for CLOUD Act and transfer diligence even if mail servers stay in Germany.	Not listed
No public ISO/SOC or independent audit	Medium Security assurance is first-party documentation only. Regulated buyers will need questionnaires, AVVs, and possibly on-request evidence.	Not listed
Freemail is ad-supported	Low Free tier includes advertising as a service component. Paid tiers are marketed as ad-free; verify current footer/banner behaviour on the live product.	Not listed
Owner-operated scale limits	Low Independent DE operator (not VC-backed hyperscale). Expect SME-grade support hours and product depth rather than global enterprise SLAs.	Not listed
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

eclipso Mail Europe

Best fit when

Individuals and freelancers who want German mail with Thunderbird/Outlook IMAP and optional OpenPGP without a bridge
SMEs needing a custom domain, German server claims, and an Art. 28 DPA on the Business plan
Buyers who prefer prepaid terms that end automatically over auto-renewing Big Tech suites
Users who still send SMS, fax, or hybrid physical post from the same account
Teams migrating from Gmail/Outlook that value CalDAV/CardDAV and a bundled drive/organizer

Poor fit when

Orgs that require zero-access architecture where the provider never stores decryptable mailbox keys by default
Enterprises needing public ISO 27001/SOC 2 reports, SCIM/SSO, or multi-tenant admin
Buyers who refuse any US-group payment or website tooling (Stripe, PayPal, Google reCAPTCHA/ads)
Users seeking open-source or self-hosted mail only

Consider instead when

When: You want a simple paid-only German privacy mailbox without freemium advertising
Consider: Posteo
Posteo is ad-free paid; eclipso differentiates with freemail and hybrid channels
When: You prioritise always-on encryption over standard IMAP clients
Consider: Tuta or Proton Mail
Tuta uses proprietary E2EE clients; Proton needs Bridge for full IMAP-style access
When: You need a broader paid German workplace suite with stronger enterprise packaging
Consider: mailbox (formerly mailbox.org)
Compare admin, audit, and collaboration depth on current vendor docs
When: You need Google/Microsoft collaboration depth more than EU operator control
Consider: Gmail or Microsoft 365
Different jurisdiction and data-use models

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

eclipso Mail Europe

Can non-Business tariffs obtain a signed Art. 28 DPA and full subprocessor list on request?
Is Speedloc the sole host for mailbox content (not only the marketing site), and are backup/DR locations exclusively in Germany?
Are independent penetration tests or ISO plans available under NDA for enterprise buyers?
What exact data minimisation applies to freemail advertising versus paid ad-free tiers (inbox content vs account metadata)?
How are OpenPGP private keys encrypted at rest in the account store, and is export/deletion documented for offboarding?

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).
