Soverin hosts email for your own domain, with aliases, webmail and access through compatible email apps. Calendar and contact synchronization use CalDAV and CardDAV, while email clients connect through IMAP and SMTP.
You can bring a domain or register one through Soverin, import an existing mailbox and enable two-factor authentication. Mailbox and domain charges are separate items to check, and additional mailboxes can be managed for a team.
