Spark (Readdle): sovereignty score and 8 European alternatives

Spark is an email client from Readdle for Mac, iOS, Android and Windows. The app combines IMAP, iCloud, Exchange, Outlook, Yahoo and Google accounts in one inbox and offers features such as priority emails, a Gatekeeper that screens unknown senders, snoozing, send later and reminders. Spark +AI helps write, translate and summarise emails. Teams can draft together, delegate emails and add private comments. Spark is delivered as an app with cloud features; the email itself stays on the server of your mail provider.

The provider is Spark Mail Limited, part of the Readdle group. Spark does not run its own servers: according to its help centre, the infrastructure is hosted by Google in the US, and features such as Teams, templates and Send Later store encrypted mail data there. Spark says it uses this data only for product optimisation and does not share it with third parties. For a European organisation, this is an app with US hosting: those cloud features process data in the US.

Why digital sovereignty matters with Spark (Readdle)

Spark (Readdle) is headquartered in IE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Spark (Readdle) hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Spark (Readdle) 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 Spark (Readdle) together with your other vendors and gives a total score, a heatmap and the main risk drivers.
