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.

web.de

E-Mail made in Germany alliance transport
Founding member of the German provider alliance (WEB.DE, GMX, 1&1, STRATO, T-Online, freenet). TLS on paths inside the alliance, mail stored in Germany, and green checkmarks on alliance addresses in the compose UI. Does not encrypt content to non-alliance or non-PGP recipients end-to-end by default.
FreeMail + paid upgrades with intelligent inbox
Ad-supported FreeMail with integrated calendar, contacts, and Online-Speicher. Intelligent inbox categorizes newsletters, orders, social, and contracts/subscriptions without duplicating messages; optional package tracking via DHL, DPD, and GLS when consented. Paid tiers expand quotas and reduce ad/tracking friction under Consent or Pay.
Optional PGP and free 2FA
Optional PGP end-to-end encryption for sensitive mail (both parties need keys/compatible clients). Optional free two-factor authentication for account login. Baseline mailbox protection relies on account credentials, spam/virus filters, and TLS—not default E2EE for every message.
Cloud made in Germany Online-Speicher
Mailbox-integrated cloud with browser, app, and desktop access; link sharing and Online Office for documents. Vendor claims exclusive German data-center storage and TLS in transit under Cloud made in Germany. Free tier includes a starter cloud quota; larger capacities are paid add-ons. Not a full Google Drive/OneDrive collab suite.
German consumer portal on the same identity
News, services, WEB.Cent cashback, and optional Deutsche Post letter preview sit beside mail. Useful for personal DACH users; increases advertising and partner surface versus a pure mailbox product. Portal embeds and partners are consent-gated where required.

Assurance & compliance: Mailo vs web.de
Assurance & compliance	Mailo	web.de
Independent security / no-logs audit	Not found Charter claims no commercial reading of messages; automated AV/spam scanning on servers. No public third-party audit PDF found.	Not found No public independent no-logs or full security audit package found for FreeMail; alliance pages claim oversight by data-protection function and independent Prüfstellen at a high level only.
ISO 27001	Not found No ISO 27001 claim found on legal/security/primary pages researched.	Not found No public ISO 27001 certificate page located for the web.de freemail product during research.
SOC 2 / SOC 3	Not found No SOC 2/3 report referenced on public product pages.	Not found No public SOC 2/3 report found for web.de FreeMail.
GDPR / EU data protection	Vendor claimed French controller; privacy rules cite GDPR and French correspondence secrecy; DPO at dpo@mailo.com; France storage claim.	Vendor claimed German controller (1&1 Mail & Media GmbH); detailed GDPR privacy notice; DE storage claims for mail/cloud. Not a legal certification.
US CLOUD Act exposure (indicative)	Partial EU entity / no known US parent / France-claimed mail hosting, but Verifone and PayPal (US-group) on payment path; full infra subprocessors unpublished. Assessment only—not legal advice.	Partial EU/German entity and parent; no known US parent; mail/cloud claimed on company-owned DE data centers. Partial because privacy notice allows third-country transfers with safeguards, FreeMail uses ad/TCF partners, and no exhaustive public subprocessor inventory. Not legal advice.
Data processing agreement (B2B)	Not found Privacy rules and terms cover processing; no standalone public B2B DPA download found—request via DPO or Pro channel.	Not found Consumer freemail focus; no clear self-serve public B2B DPA for FreeMail found. Request under contract if treating as processor for an organization.
EU AI Act	Not applicable Traditional email/cloud suite; not marketed as an AI system product.	Not applicable Consumer mail/portal with limited in-product assistants; not an AI-centric product for this checklist.

Considerations & known limitations: Mailo vs web.de
Considerations & known limitations	Mailo	web.de
PGP is server-side trusted third party	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.	Not listed
Incomplete public subprocessor inventory	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.	Not listed
US-group payment processors	Low Checkout shares email with Verifone/Paybox; PayPal is also offered. Limited to billing path per privacy rules, but relevant to CLOUD Act diligence.	Not listed
Free tier third-party advertising	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.	Not listed
No public ISO/SOC or independent security audit	Medium Security posture relies on first-party statements and internal measures. Procurement teams may need questionnaires or NDA evidence.	Not listed
Free accounts deleted after inactivity	Low Mailo Free unused for 365 days can be deleted with content loss. Premium/Pro have different retention rules—plan backups and renewals.	Not listed
Ad-financed FreeMail and consent surface	Not listed	Medium FreeMail uses advertising and Consent or Pay. With consent, content may feed interest profiles; FreeMail users cannot drop WEB.DE informiert like paid tiers. Unsuitable where ad-tech processors are banned.
No default end-to-end encryption	Not listed	Medium TLS and alliance transport protection are not content E2EE. Optional PGP only covers willing counterparties. Operator can process plaintext for spam, intelligent inbox, and consented ad analysis.
Limited public audit/cert artifacts	Not listed	Medium ISO 27001, SOC 2, and independent no-logs audits not found on public product pages. Trust rests on German entity, DE hosting claims, and first-party security copy.
Third-country transfers and portal partners	Not listed	Low Privacy notice contemplates non-EEA recipients under Chapter V safeguards. Portal/search/ID/ad features introduce extra processors beyond the mailbox DC story—review consent layer and purpose before sensitive use.
FreeMail inactivity content deletion	Not listed	Low Privacy notice: FreeMail email content may be deleted after more than 180 days without login. Not a durable archive without activity or export.

Fit

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

web.de

Best fit when

German consumers who want a familiar .de freemail address with portal news and everyday cloud storage
Secondary personal or family mail where DE operator and DE storage matter more than default E2EE
Users who value intelligent inbox sorting, package tracking, and mobile/desktop access over privacy-maximalist design
Teams comparing Gmail/Outlook.com alternatives on jurisdiction while accepting consumer freemail trade-offs
Buyers already in the United Internet ecosystem (WEB.DE / GMX) who need a consistent DACH brand

Poor fit when

Organizations needing primary business mail with admin console, SSO, and signed B2B DPA as standard
Hard requirements for default end-to-end encryption or zero advertising/tracking surface
Self-hosted or open-source mail stacks you operate yourself
Long-term cold archives on FreeMail (inactivity deletion policy)
Procurement policies that forbid ad-tech partners or third-country transfer language without contract exhibits

Consider instead when

When: You need default E2EE and a privacy-first paid mailbox
Consider: Tuta or Proton Mail
web.de PGP is optional and counterpart-dependent; FreeMail is ad-financed.
When: You want ad-free German/EU mail with strong consumer privacy posture and paid model only
Consider: Posteo or mailbox.org
Less portal monetization; clearer privacy-first product framing than mass freemail.
When: You prefer the same United Internet Mail & Media stack under another brand
Consider: GMX Mail
Nearly aligned trust and capability story; brand and portal mix differ.
When: You need Google/Microsoft-class workspace collab and enterprise compliance packs
Consider: Gmail (Google Workspace) or Outlook.com / Microsoft 365
Trade DE freemail residency story for US-group platforms and deeper admin tooling.

Open questions for due diligence

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?

web.de

Will 1&1 Mail & Media sign a B2B DPA and provide a current subprocessor list for mailbox and cloud processing?
Are there ISO 27001, C5, or independent penetration-test summaries available under NDA for Mail & Media freemail infrastructure?
For your use case, is FreeMail with ads acceptable, or must you force paid TrackFree/premium paths and refuse intelligent-inbox/ad consents?
Confirm whether any non-DE backup, support, or analytics processors touch mailbox content beyond the public privacy notice.
