Mailo: sovereignty score and 8 European alternatives

Mailo is a French email service for individuals, families and organisations. It offers webmail, a calendar, storage for documents and photos, aliases and apps for iOS and Android, with access over IMAP and Exchange ActiveSync. There is a free version, which shows advertising banners, and a paid Premium version with more storage and aliases. There are also Mailo Pro for businesses and organisations, Mailo Edu for schools and Mailo Junior for children aged 6 to 14. It is delivered as software as a service and the product is not open source.

Mailo is operated by Mail Object, based in Saint-Maur-des-Fossés, France. According to the company, all data is stored on secure servers in France. No foreign parent company is named. For a European organisation, Mailo is therefore a provider with its headquarters and data storage inside the EU, with French law and the GDPR as the framework. Anyone who wants a fully ad-free service should check the terms of the chosen version, because the free version displays advertising.

Why digital sovereignty matters with Mailo

Mailo is headquartered in FR and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so Mailo scores best on data residency.

Mailo is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Mailo together with your other vendors and gives a total score, a heatmap and the main risk drivers.
