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.

RAIDBOXES Emails

Germany· Email Services

Needs review

Shortlist when you already (or will) host the domain and WordPress stack at RAIDBOXES and need practical multi-mailbox domain email under a German operator with an online DPA. Skip when you need multi-domain density, default E2EE, or email fully independent of a hoster—consider Migadu, Tuta, Posteo, or mailbox.org instead.

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.

RAIDBOXES Emails

Mail Hosting 2.0 on RAIDBOXES infrastructure
IMAP/SMTP mailboxes on dedicated hostnames (mail-rb.securemail.pro / smtp-rb.securemail.pro) after the move off the prior mailbox.org cooperation. Vendor claims German data-centre locations and triple-redundant mail servers. Best for teams that want domain mail under the same German WordPress host rather than a separate privacy-mail brand.
Multi-mailbox plans with aliases, forwards, and catch-all
Tiered plans allocate a fixed number of mailboxes and a shared storage pool, plus per-mailbox alias and forwarding quotas, autoresponders, and catch-all (requires a dedicated catch-all mailbox). One connected domain per plan—confirm multi-domain needs before shortlisting.
Spam/virus filters, TLS, optional PGP, ad-free inboxes
All plans include spam and virus filtering, SSL/TLS for transfer, a blacklist checker, webmail, and ad-free inboxes. PGP is optional rather than default end-to-end encryption for every message—teams that need mandatory E2EE workflows should evaluate Tuta or a full mailbox.org stack instead.
Dashboard-adjacent domain and WordPress ops
Mailboxes are ordered from the RAIDBOXES dashboard and are intended to sit next to WordPress hosting and domain management. New RAIDBOXES mailboxes require the domain to be hosted with RAIDBOXES; legacy mailbox.org-linked domains follow a separate migration path documented in the help centre.
Online B2B DPA and German operator
Raidboxes GmbH (Münster) offers an online data processing agreement (AV contract) with technical-organisational measures. Useful for agencies that already sign a DPA for WordPress hosting and want the same counterparty for domain email—still review TOMs and subprocessor scope for mailbox vs platform tooling.

Considerations & known limitations: Mailo vs RAIDBOXES Emails
Considerations & known limitations	Mailo	RAIDBOXES Emails
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.	Medium B Corp is not a security certification. Enterprise security questionnaires may need NDA materials or alternative providers with published audits.
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
Domain must be hosted at RAIDBOXES	Not listed	Medium New mailboxes require the domain on RAIDBOXES. That is convenient for WP customers and a lock-in factor if you only wanted independent mail.
One connected domain per plan	Not listed	Medium Multi-domain operators need multiple plans or another provider; not a Migadu-style multi-domain account model.
PGP optional, not default E2EE	Not listed	Medium Threat models that assume provider-side unreadability by default are a better fit for Tuta or similar products.
US-group platform subprocessors	Not listed	Medium Privacy policy discloses AWS EMEA, DigitalOcean, Intercom, Chargebee, Google tools, Mailgun, and others for website/support/billing/marketing—even while email marketing claims German mail servers. Scope diligence to mailbox vs platform data paths.
Privacy policy may lag Mail Hosting 2.0	Not listed	Low §Email box still lists mailbox.org/Heinlein while marketing claims first-party hosting—confirm live stack and subprocessor annex for your contract.

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

RAIDBOXES Emails

Best fit when

WordPress agencies and freelancers standardising on RAIDBOXES for sites, domains, and mail admin
SMEs wanting professional multi-mailbox domain email with standard IMAP clients—not a full Google/Microsoft suite
Teams that need catch-all, aliases, forwards, autoresponders, and ad-free inboxes on one domain
Buyers who require a German legal counterparty and an online B2B DPA for processor agreements
Operators migrating off legacy mailbox.org-linked RAIDBOXES mail toward first-party Mail Hosting 2.0

Poor fit when

Multi-domain mail estates that need many domains under one contract (one connected domain per plan)
Policies requiring default end-to-end encryption for all mail (PGP is optional only)
Buyers who refuse any coupling between mailbox service and domain/WordPress hosting
Teams seeking a full office suite (Drive, collaborative docs, built-in video) rather than domain mail
Procurement that demands public ISO 27001/SOC 2 or independent no-logs audit reports for the mail product

Consider instead when

When: You need multi-domain, usage-based professional mail without WordPress host lock-in
Consider: Migadu
Swiss-operated, standards-based hosting priced by quotas rather than per-domain WordPress adjacency
When: You need default E2EE and a privacy-first client model
Consider: Tuta
Different threat model; less IMAP flexibility than RAIDBOXES
When: You want privacy-oriented German personal/business mail without hosting coupling
Consider: Posteo or mailbox (formerly mailbox.org)
mailbox is also the former RAIDBOXES mail partner and a deeper digital-workplace option
When: You need Google/Microsoft suite collaboration, not just domain mailboxes
Consider: Google Workspace or Microsoft 365
US Big Tech residency and CLOUD Act profile differ sharply—use only if suite features dominate

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?

RAIDBOXES Emails

For a new Mail Hosting 2.0 mailbox, is mailbox.org/Heinlein still a subprocessor for mailbox content, or only a legacy path?
Which German data-centre operators and exact regions host mail storage and backups (primary + DR)?
Does the standard DPA/TOM annex explicitly cover email hosting subprocessors separately from WordPress hosting?
What are published RPO/RTO and restore procedures for mailbox backups?
Are there any upcoming multi-domain plan options or reseller mail SKUs?
