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.

Inbox.eu

100 GB mailbox plus integrated Files storage
Premium accounts include a large combined email-and-files quota (business adds domain-level shared storage). Files supports multi-gigabyte uploads, share links, parallel downloads, and WebDAV mounting on desktop—useful for SMEs that want drive-like sharing without a separate vendor.
Custom domains with business admin panel
Business email lets you host unlimited domain mailboxes after DNS/MX validation, with admin controls for users, aliases, catch-all, and domain settings. A public demo of the admin experience is available for evaluation before signup.
Standard protocols plus mobile apps
Full IMAP, POP3, and SMTP (with TLS) for Thunderbird, Outlook, and other clients; calendar and contacts sync; official apps on iOS and Android. Fits teams that refuse webmail lock-in.
TLS, 2FA, spam filtering, and business SSO
Transport encryption with TLS 1.2+, optional two-factor authentication, multi-filter spam/malware scanning, and Business SSO via SAML 2.0 or LDAP (including common IdPs such as Azure AD and Google Workspace). This is hosted-email security, not zero-knowledge E2E.
Migration support and human multilingual help
Documented IMAP/CSV migration paths from Gmail and other providers, plus real-person support in English and Baltic languages rather than chatbot-only queues—material for SMEs without a dedicated mail ops team.

Considerations & known limitations: eclipso Mail Europe vs Inbox.eu
Considerations & known limitations	eclipso Mail Europe	Inbox.eu
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.	Not listed
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
No public ISO/SOC or independent audit	Not listed	Medium Enterprise RFPs that require cert packs will stall until the vendor supplies private assurance materials.
Not zero-knowledge E2E mail	Not listed	Medium Operator-controlled storage with TLS in transit; legal-process access is acknowledged. Do not shortlist as a Proton/Tuta crypto peer.
US-group tools on website privacy path	Not listed	Medium Google Analytics, Meta Pixel, hCaptcha, and InMobi appear in the privacy policy even while mail is marketed as Latvia-only—align transfer assessments and cookies consent with this split.
Public DPA / subprocessor list gap	Not listed	Medium Processor language exists in TOS, but buyers still need a signed DPA and current subprocessors for regulated personal data.
Operator also runs ad-supported portals	Not listed	Low Inbokss group products include advertising-supported regional portals; verify contractually that paid Inbox.eu mailboxes stay ad-free and outside portal ad profiling.

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

Inbox.eu

Best fit when

SMEs wanting branded domain email without Google Workspace or Microsoft 365 suite lock-in
Teams that standardise on Thunderbird, Outlook, or other IMAP/SMTP clients
Buyers prioritising large included mailbox and file quotas plus WebDAV sharing
Organisations that need business SSO (SAML 2.0 or LDAP) without a separate SSO SKU
Users seeking an ad-free paid European mailbox with human support in English and Baltic languages

Poor fit when

RFPs that require published ISO 27001, SOC 2, or independent security/no-logs audit reports
Threat models that assume the provider cannot access plaintext mail (zero-knowledge E2E)
Buyers needing a downloadable public DPA and full mail-path subprocessor register before any sales contact
Teams that need a full office suite (docs, sheets, meetings) rather than email-plus-files

Consider instead when

When: You need open or heavily audited zero-knowledge end-to-end encrypted mail
Consider: Proton Mail or Tuta
Different crypto posture than TLS-hosted conventional mail
When: You prefer German jurisdiction and a long-standing privacy-host reputation
Consider: Posteo or mailbox.org
Often leaner storage; strong EU privacy positioning
When: You already depend on Docs/Drive/Meet or full Microsoft 365 collaboration
Consider: Google Workspace or Microsoft 365
Inbox.eu is not a suite replacement
When: You want Belgian dual-key / open-source-oriented secure mail
Consider: Mailfence
Different feature and crypto tradeoffs

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?

Inbox.eu

Will SIA INBOKSS sign your organisation's DPA and provide a current subprocessor list limited to production mail/file paths?
Are there private ISO, SOC, or penetration-test reports available under NDA?
Which backup media/locations and any non-EU operational tooling (support remote access, payments) process personal data?
Does business SSO support your exact IdP configuration (SAML attributes / LDAP schema) without custom engineering fees?
