Needs review

Shortlist GMX Mail for consumer or light-professional freemail when you want a German United Internet operator, claimed German mailbox data centers, large free storage, and standard IMAP/POP—with optional OpenPGP. Skip when you need zero-access encryption by default, enterprise DPA/audit packs, or an ad-free architecture as the baseline; consider Proton Mail instead.

Cloud Mail

  • 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.

GMX Mail

  • Large free mailbox storage with open protocols

    gmx.com free accounts advertise up to 65 GB email storage and 50 MB attachments. POP3, IMAP, and SMTP are supported after you enable them in settings (TLS 1.2+; imap.gmx.com / mail.gmx.com). Suits users who want client choice (Thunderbird, Outlook, mobile) without Google or Microsoft as the mailbox host.

  • Optional OpenPGP end-to-end encryption (Mailvelope)

    GMX offers free OpenPGP messaging via the Mailvelope browser extension: key generation, local key storage, key directory, and mobile recovery. Encryption is opt-in per message after setup—not whole-mailbox zero-access by default. Best for occasional sensitive threads when both parties can use OpenPGP.

  • Aliases, Mail Collector, and multi-account inbox

    Create up to 10 alias addresses (including other GMX domains) managed in one inbox, and pull up to 10 external accounts via Mail Collector. Useful for freelancers and project mail without juggling multiple passwords or providers day-to-day.

  • Spam filtering, antivirus, and optional TOTP 2FA

    Free accounts include automated spam filtering (user blacklist and optional improved detection) and antivirus scanning of mail and cloud files. Optional two-factor authentication uses an authenticator app (TOTP); third-party clients use app-specific passwords when 2FA is on.

  • Bundled Cloud, calendar, contacts, and Online Office

    Accounts include contacts, calendar/organizer, about 2 GB GMX Cloud with share links, and Online Office for common document formats—enough for light personal productivity without a separate suite subscription.

Vendor claimed

EU/German controller; public privacy notices under GDPR; DPO published; supervisory authorities named (BfDI / LfDI RLP).

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

German entity and parent (United Internet AG); mailbox data claimed in German DCs. Partial/medium because portal analytics include Google LLC tools, freemail ads involve international partners, and no full public mail-infra subprocessor list. 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.

Not found

Product is primarily consumer FreeMail under GTCs/privacy policy; no public self-serve B2B DPA flow found for FreeMail shortlisting.

EU AI Act
Not applicable

Cloud Mail is conventional email hosting, not an AI product.

Not applicable

Not an AI-centric product; optional assistive features may appear in product privacy text but FreeMail is not marketed as an AI system.

Considerations & known limitations: Cloud Mail vs GMX Mail
Considerations & known limitationsLogo: Cloud MailCloud MailLogo: GMX MailGMX Mail
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
Advertising-funded free tierNot listed
Medium

FreeMail depends on ads and (with consent) interest-based targeting and partner sharing. Privacy posture differs from paid privacy mail. Practical impact: expect consent UX, ad surfaces, and partner lists—not a zero-ads default.

E2E encryption is optional, not defaultNot listed
Medium

Without OpenPGP setup, mailbox content is accessible to the provider like conventional hosted mail. Practical impact: do not treat GMX FreeMail as zero-access encryption architecture.

Incomplete public infrastructure subprocessorsNot listed
Medium

Residency for mail is claimed (Germany/EU), but there is no enterprise-style published subprocessor inventory for core mail infrastructure. Portal paths name Google Analytics and global ad partners. Practical impact: extra questionnaire work for high-assurance buyers.

Inactivity and freemail operational policiesNot listed
Low

Terms/privacy allow deletion of free mailbox content after prolonged inactivity (about 180 days without login on FreeMail privacy text). Practical impact: inactive project addresses can disappear if not maintained.

No public ISO/SOC package for FreeMailNot listed
Low

Security pages emphasize product features (spam, AV, 2FA, PGP) rather than downloadable ISO/SOC evidence for FreeMail. Practical impact: may fail enterprise vendor security questionnaires without further vendor dialogue.

Fit

Cloud Mail

Best fit when

  • SMEs and freelancers needing custom-domain business mail without a full Google/Microsoft suite
  • Teams that want classic IMAP/SMTP clients plus Roundcube webmail and CalDAV/CardDAV
  • Resellers seeking WhiteLabel managed mail on a European host
  • Organizations already using Seeweb compute/hosting that want mail in the same vendor relationship
  • Buyers prioritizing Italian legal entity, published ISO scopes that include mail, and CISPE-oriented residency messaging

Poor fit when

  • Threat models that require default end-to-end encryption or zero-access provider architecture
  • Need for full collaborative office suites, deep directory SSO, or Graph/Workspace app ecosystems
  • Teams that must self-host the MTA stack rather than buy managed mail
  • Procurement that requires a public SOC 2 report or a fully published subprocessor list before first contact

Consider instead when

  • When: You need zero-access / end-to-end encrypted mailboxes as the primary control

    Consider: Proton Mail or Tuta

    Different product class: E2EE-first vs conventional managed IMAP hosting

  • When: You need mail plus full productivity suite and global enterprise ecosystem

    Consider: Google Workspace or Microsoft 365

    Trade EU-operator focus for suite breadth and US-jurisdiction diligence

  • When: You want another European professional domain-mail host for comparison

    Consider: Migadu, Mailfence, or Combell E-mail

    Compare admin model, spam handling, restore RPO, and contract artifacts

GMX Mail

Best fit when

  • Individuals and freelancers who want a European freemail address with large free storage and IMAP client freedom
  • Users consolidating multiple addresses via aliases (up to 10) and Mail Collector
  • Buyers who prefer a German legal controller (1&1 Mail & Media GmbH / United Internet) over US Big Tech freemail
  • Teams that only need optional OpenPGP for specific sensitive threads, not zero-access by default
  • Users already familiar with GMX/WEB.DE in German-speaking markets who need international domains (e.g. gmx.com)

Poor fit when

  • Organizations that require default end-to-end / zero-access encryption for all mail
  • Procurement that needs a published independent security audit pack, ISO/SOC evidence, and a B2B DPA as standard shortlist inputs
  • Teams that cannot accept advertising-funded freemail economics or interest-based ad consent UX
  • Custom-domain corporate mail and admin controls at Microsoft 365 / Google Workspace depth
  • Self-hosted or open-source mail stack requirements

Consider instead when

  • When: You need zero-access encryption by default and a privacy-first paid model without ad-funded freemail as the core product

    Consider: Proton Mail

    Proton is the stronger shortlist peer in this catalog for E2E-first evaluation.

  • When: You need Google Workspace-class collaboration and are willing to accept US Big Tech jurisdiction

    Consider: Gmail / Google Workspace

    Richer suite integration; different sovereignty and ad/ecosystem tradeoffs.

  • When: You need Microsoft ecosystem mail, calendar, and compliance tooling

    Consider: Outlook.com / Microsoft 365

    Strong enterprise admin story; US parent and CLOUD Act path differ from GMX.

Open questions for due diligence

Cloud Mail

  • Will Seeweb provide a signed Art. 28 DPA and current subprocessor list for Cloud Mail content?
  • Which data center hosts a given Cloud Mail instance (Italy vs other European Seeweb/group sites), and can residency be constrained contractually?
  • Which external reputation / antispam intelligence providers are used, and where do they process metadata?
  • Is there a SOC 2, independent penetration test summary, or customer-available audit package under NDA?
  • What are exact SLA credits, RPO/RTO for mail, and support tier inclusions for pure Cloud Mail (vs Global Support for servers)?

GMX Mail

  • Will 1&1 Mail & Media sign a B2B DPA and publish a current mail-infrastructure subprocessor list for our use case?
  • Are FreeMail mailbox systems solely on United Internet / 1&1 operated German DCs, or are any US-group cloud providers used for primary storage, backup, or DR?
  • What independent audits or certifications (if any) cover the FreeMail platform beyond the Mailvelope/OpenPGP path?
  • For paid/premium mailboxes: which advertising and tracking paths remain, and what contractual residency language is available?
