Soverin is operated by Soverin B.V. (Amsterdam, KvK 61552275) and has been running since around 2014 as an independent, self-funded Dutch email provider: no VC backing, no US parent. The service is paid-only (from €3.25/mo / €39/yr, with optional .nl domain at €13/yr); there is no free tier, which is consistent with the "no ads, no profiling, no third-party data" pitch. Mail, calendar and contacts are reachable via standard IMAP / SMTP / CalDAV / CardDAV with any client. Soverin deliberately does not implement end-to-end encryption in the Proton/Tuta sense, in exchange for that full protocol compatibility; data is encrypted in transit (TLS) and at rest on the storage layer, and per the privacy statement is processed only within the EU. Certifications held: ISO 27001, ISO 14001, ISO 9001, NIS2 Ready Mark, perfect Internet.nl score (DNS / email / web / IPv6); NEN 7510 (Dutch healthcare InfoSec) listed as in-progress. The privacy statement names one unnamed sub-processor (external first-line customer support, under DPA + ISO scope) but the document is not a publicly linked customer-facing DPA, the key remaining gap given the otherwise clean EU ownership, EU hosting, and multiple ISO certifications. Positioning is squarely against US free webmail (no CLOUD Act exposure); UI in English and Dutch.
