Soverin
VERIFIEDIndependent Dutch paid email (from €3.25/mo); ISO 27001 + NIS2 Ready, all data in Netherlands, full IMAP/SMTP/CalDAV/CardDAV compatibility.
Why this score?
Soverin is operated by Soverin B.V. (Amsterdam NL, KvK 61552275, founded ~2014), an independent Dutch email provider with paid-only mailboxes (from €3.25/mo), all data hosted in the Netherlands under EU law, no US parent and explicitly positioned against CLOUD Act exposure. Holds ISO 27001 / 14001 / 9001, NIS2 Ready Mark, full Internet.nl score, NEN 7510 in progress. Capped at 3/5 because there is no publicly linked DPA, no public sub-processors list (privacy statement mentions one unnamed external first-line support partner), and the service is TLS-encrypted, not end-to-end encrypted unlike Proton Mail or Tuta — a deliberate trade-off for full IMAP/SMTP/CalDAV/CardDAV compatibility with any client.
