Lockbin vs RMail

Lockbin is a web application for sending private email messages and files. Recipients can open a message using a unique URL and password; passwordless secure links are also available for known recipients. Messages use TLS in transit and FIPS 140-2 verified AES-256 encryption at rest. Decryption keys are held by the sender and recipient rather than stored in plaintext on Lockbin servers. It works in Chrome, Firefox, Safari, or Edge without a download or installation, and is listed for Linux, macOS, web, and Windows. Lockbin works alongside Google Workspace and Microsoft 365 without a plugin or extension. Premium users can create file-drop links or secure forms to receive files without requiring an account or password. The free plan covers one user, 25 MB attachments, and six months of inbox storage; the site also advertises 10 free messages with no credit card required. Premium costs $10 per user per month. Uncollected messages are destroyed after six months, and read files not marked for deletion are removed within 24 hours.

RMail is a paid email service for protected message and attachment delivery. It supports delivery by attachment, password-based recipient verification, and message expiry. The attachment limit is 10. RMail runs on the web, Windows, and macOS, with Outlook and Gmail integrations and admin access controls. RMail, the maker, was founded in 2000. Four plans are listed, although prices are not provided: RMail Personal includes 25 units per month; Standard includes 200 units per month; and Business includes 500 units per month. Enterprise lists Email Eavesdropping Alerts, Custom Integrations, SSO, and a Cloud Email Security Gateway. The plan structure therefore separates monthly unit allowances from enterprise-oriented controls and integrations. Password verification and expiry address recipient access, while the Outlook and Gmail connections fit users working through those services. The listed pricing model is paid, and no plan price is stated.
