Our verdict on Soverin
Soverin is a privacy-focused email hosting service for individuals, professionals, and small businesses. Its Private mailbox plan provides 25 GB of storage, unlimited aliases, custom-domain use and registration, calendar and contact synchronization, and access through standard email protocols. Users can connect through IMAP and SMTP, with CalDAV and CardDAV support for calendars and contacts. Soverin hosts data in Europe and supports web, iOS, and Android access, while business customers can manage multiple mailboxes and domains.
According to the vendor’s pricing page, the Private mailbox plan costs €3.25 per user per month when billed annually. The plan includes 25 GB of mailbox storage, unlimited aliases, calendar and contact synchronization, European hosting, and a 30-day money-back guarantee. The published feature set also includes encrypted connections to email servers, two-factor authentication, email import and export, spam filtering, and email filters. There is no free plan, so Soverin is aimed at buyers prepared to pay for a dedicated mailbox rather than users seeking a no-cost starting tier.
Soverin’s strongest fit is its combination of mailbox capacity, alias flexibility, custom domains, and portability across established email applications. It lists compatibility with Airmail, Apple Mail, Microsoft Outlook, Thunderbird, Roundcube, and Aurora, giving users several client options beyond the web interface. Calendar and contact synchronization extend the service beyond basic email, while open-standard access supports migration and external applications. Choose Soverin if you want a paid, privacy-oriented mailbox with aliases and domain control. Consider an alternative if a free plan, broader platform coverage, or a different pricing structure matters more.
