The web-based email service uses recipient verification through two-factor authentication. Sending a secure message requires the recipient’s email address and telephone number. Features include identity checks, recipient notifications and a burn-after-reading option. The provider describes separate message and storage encryption, with message data stored in Sweden.
SecureMailbox offers a Pro trial that moves to a Lite plan after 28 days. Basic personal use is free, while premium services and external services such as SMS can incur charges. The documentation also notes that normal email or SMS notifications can include message titles unless neutral notifications are selected.
External recipients register a free account before opening their first secure message. Senders can see whether none, some or all recipients have read it, with optional SMS read notifications.
