Mailo

France· Email Services

Needs review

Shortlist Mailo when you want French-entity freemium webmail with classic IMAP/EAS clients, integrated calendar/cloud, supervised Mailo Junior for kids, or Pro custom domains for SMEs—without US Big Tech accounts. Skip when you need default zero-knowledge E2EE, open-source/self-host, or a full Workspace-class suite; consider Tuta, Proton Mail, or Infomaniak kMail instead.

Migadu

Switzerland· Email Services

Needs review

Shortlist Migadu when you need Swiss-operated, standards IMAP/SMTP hosting with unlimited addresses across many domains under flat account quotas—especially agencies and multi-domain SMEs. Skip when you need provider E2EE defaults, contractual SLA on the default offer, mailbox 2FA, or bulk/transactional sending; consider Proton Mail/Tuta for E2EE, or mailbox.org/Mailfence/Posteo/Runbox for other European professional-mail tradeoffs.

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.

Migadu

Usage-metered accounts with unlimited addresses
Plans are flat per Migadu account. Within daily in/out quotas and soft storage guidance, create large numbers of mailboxes and host many domains without per-address fees—useful for agencies and multi-project teams. Soft storage does not hard-bounce mail; sustained over-quota use can force upgrades or limits.
Standards SMTP, IMAP4, POP3, and webmail
No proprietary client protocol. Connect Thunderbird, Apple Mail, Outlook, mutt, and others over TLS (typical endpoints imap.migadu.com:993, smtp.migadu.com:465, pop.migadu.com:995). ManageSieve filtering, aliases, pattern rewrites, identities, footers, auto-responders, and optional catch-alls cover classic postmaster needs. Data remains portable via standard protocols.
Multi-domain admin, multi-admin, and beta API
Agencies can hold many client domains under one roof, open multiple administrators (domain-scoped on higher plans), set per-domain/mailbox limits, and monitor traffic. A REST API (documented as early beta) manages domains, mailboxes, identities, forwardings, aliases, and rewrites for automation. Domain deletion stays UI-only as a safety measure.
DNS helpers and postmaster-style support
Optional built-in DNS ships mail records preconfigured; Migadu also offers DNS setup help at no extra fee and publishes diagnostics/activation flows. Support is ticket-based from people who operate the mail stack—not outsourced chat—with plan-dependent urgency outside office hours.
No ads, no product analytics cookies
Vendor policy states no advertising, no tracking of mailbox content for ads, and no website analytics cookies beyond session needs. Processing is framed for service delivery, abuse prevention, and legal obligations. Payment data still goes to Stripe and PayPal under separate processor terms.

Considerations & known limitations: Mailo vs Migadu
Considerations & known limitations	Mailo	Migadu
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
US payment subprocessors (Stripe, PayPal)	Not listed	Medium Billing-related personal data can transfer to US processors under Migadu’s privacy policy. Mail content path is France/EU per vendor, but payment data is a separate CLOUD Act / transfer surface.
Incomplete public infrastructure subprocessor list	Not listed	Medium Primary pages name France hosting and certified DCs without a full vendor inventory for compute, storage, and backups. Procurement should request the current list and regions in writing.
No E2EE product default; no classic mailbox 2FA	Not listed	Medium Standards mail with TLS; vendor recommends user-side OpenPGP for strong content secrecy. IMAP 2FA is not offered; app-specific-style identities are not second-factor MFA.
Daily quotas and human-mail policy	Not listed	Medium Account-wide daily in/out caps and anti-bulk rules make Migadu unsuitable as a transactional/marketing ESP. Over-limit mail can be deferred or rejected after tolerance.
No default SLA on standard plans	Not listed	Low Vendor states standard offers lack SLAs; email is treated as asynchronous and occasionally disrupted. Enterprise SLA only via separate commercial discussion.
No public independent security audit	Not listed	Medium Privacy and no-ad-scanning claims are first-party. No independent audit report found for no-logs or security controls.

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

Migadu

Best fit when

Agencies and freelancers hosting many client domains under one account with multi-admin or API provisioning
Organizations that want custom-domain mail with standard clients and portable IMAP—not a proprietary suite lock-in
Teams tired of per-seat pricing for large address spaces with modest real traffic
Buyers who value a small bootstrapped Swiss operator that publishes blunt product limits
Setups that need aliases, rewrites, identities, SIEVE, and postmaster-style controls more than collab apps

Poor fit when

Primary need is end-to-end encrypted mail by default (Proton Mail, Tuta, or user-side OpenPGP workflows)
High-volume transactional, marketing, or bulk outbound mail
Requirement for default contractual SLA, phone support, or multi-language admin UI
Mandatory mailbox 2FA on every IMAP login
Want a free long-term plan or Migadu-branded @provider addresses without owning a domain

Consider instead when

When: You need provider-managed end-to-end encryption as the default product promise
Consider: Proton Mail or Tuta
Migadu is standards hosting with TLS; content secrecy against the operator is not the design center.
When: You want another European professional host with a different admin/encryption/residency package
Consider: mailbox.org, Mailfence, Posteo, or Runbox
Compare DPA detail, audit packaging, and whether multi-domain usage pricing still wins for your address sprawl.
When: You need full workspace suite (docs, meet, identity) rather than email hosting alone
Consider: Google Workspace, Microsoft 365, or Infomaniak-style European suites
Migadu deliberately stays postmaster-focused.
When: You need bulk or high-rate application email
Consider: A dedicated ESP (not Migadu); Amazon SES is the common Big Tech baseline—pair with EU ESPs if residency matters
Migadu rate-limits and bans intentional bulk use.

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?

Migadu

What are the current named mail hosting, backup, and ancillary subprocessors and their countries?
Can Migadu provide ISO/SOC evidence for the organization or only DC-level certifications?
Is an independent security or penetration-test summary available under NDA?
Does the privacy-page DPA meet your controller’s mandatory clauses without a separate signed agreement?
What encryption-at-rest and key-management practices apply today versus the older public pro/con narrative?
