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.

Mailo

French-hosted webmail with IMAP, EAS, and classic protocols
Webmail plus IMAP4 for clients, Exchange ActiveSync for mobile sync, and POP3 on paid tiers; SMTP relay with account credentials. Vendor states mail and content stay on servers in France. Free tier is ad-supported with lower quotas; Premium unlocks POP3, more aliases, and larger mail/cloud caps. Suits teams that need standard desktop/mobile clients rather than a closed proprietary app only.
Mailo Junior supervised email for children
Child accounts (about ages 6–14) only exchange mail with contacts a parent or teacher validates. Age-adapted mini/junior UIs, no ads on Junior, optional promotion to a standard account while keeping the address. Separate Junior mobile apps. Unique fit for families and schools versus generic consumer mail.
Calendar, virtual disk, and open sync protocols
Shared calendars and tasks, address book, photo albums, and a virtual disk for files with WebDAV/FTP access. CalDAV and CardDAV for external clients. Premium+ can unlock OnlyOffice in-browser editing. Better as an all-in-one Mail&Cloud for SMEs/families than bare IMAP-only privacy mail.
Mailo Pro spaces: custom domains and mutualised storage
Pro Start/5/Modulo style plans share mail+cloud quota across accounts, support custom domains (register, transfer, or declare external), distribution lists, mailbox sharing, resource calendars, and manager tooling. Priority Pro hotline with documented acknowledgement and restoration targets for Pro subscriptions. Aimed at TPE/PME, associations, and municipalities—not a full Google Workspace clone.
Optional server-side PGP and account security controls
Built-in PGP/MIME encrypt and sign in the webmail as a trusted third party (keys managed on Mailo for multi-device convenience). Two-factor authentication, application passwords, connection history, and guardianship-style access options. Not zero-knowledge E2EE by default—use external client crypto if the provider must never hold keys.

Considerations & known limitations: eclipso Mail Europe vs Mailo
Considerations & known limitations	eclipso Mail Europe	Mailo
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
PGP is server-side trusted third party	Not listed	Medium Webmail PGP holds keys on Mailo for multi-device use. Provider-access risk differs from zero-knowledge E2EE defaults at Tuta/Proton. Use external crypto if that is a hard requirement.
Incomplete public subprocessor inventory	Not listed	Medium Privacy rules name payments, domains, and free-tier ads, but not a full list of mail storage, backup, or anti-spam infrastructure vendors. Request annex for B2B risk review.
US-group payment processors	Not listed	Low Checkout shares email with Verifone/Paybox; PayPal is also offered. Limited to billing path per privacy rules, but relevant to CLOUD Act diligence.
Free tier third-party advertising	Not listed	Low Mailo Free shows ad banners via agencies under IAB TCF consent (Sirdata CMP). Premium removes ads. Ad cookies stated as not tied to Mailo profile.
No public ISO/SOC or independent security audit	Not listed	Medium Security posture relies on first-party statements and internal measures. Procurement teams may need questionnaires or NDA evidence.
Free accounts deleted after inactivity	Not listed	Low Mailo Free unused for 365 days can be deleted with content loss. Premium/Pro have different retention rules—plan backups and renewals.

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

Mailo

Best fit when

EU individuals and families wanting French-hosted mail with calendar and cloud disk in one account
Parents/schools needing supervised child email (Mailo Junior) with contact allow-lists
French SMEs, associations, and municipalities needing custom domains and mutualised Pro storage
Teams that depend on IMAP, EAS, CalDAV, CardDAV, or WebDAV rather than a locked-in app
Buyers who accept freemium ads on free tier or low-cost Premium rather than pure prepaid anonymity mail

Poor fit when

Orgs that require default end-to-end encryption with zero-access provider architecture
Buyers that need open-source server code or official self-hosting
Enterprises needing SOC 2 / ISO 27001 evidence already published on a trust centre
Heavy Google Workspace / Microsoft 365 collaboration suites (docs/drive ecosystem depth)

Consider instead when

When: You need zero-knowledge / default E2EE webmail
Consider: Tuta or Proton Mail
Mailo PGP is optional and server-side trusted third party
When: You want German privacy mail with different encryption/product posture
Consider: Posteo or mailbox.org
Compare protocols, storage bundles, and business features side by side
When: You need Swiss multi-product cloud with mail plus broader suite
Consider: Infomaniak kMail
Different country stack and product breadth
When: You need US Big Tech ecosystem integration at any cost
Consider: Gmail or Microsoft 365 / Outlook.com
Trade EU entity and France residency claims for ecosystem depth

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?

Mailo

Will Mailo sign a GDPR Article 28 DPA with a full subprocessor and transfer annex for Pro customers?
What is the named primary data-centre operator and backup/DR location beyond the France and Ecritel website-host statements?
Is there an independent penetration test, ISO 27001 roadmap, or customer-available security whitepaper?
Where is Rainbow (video) and OnlyOffice data processed relative to the France mail claim?
Current UGAP / public procurement listing status for French public buyers?
