In their own words
Lockbin
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.
PDF Postman
PDF Postman is a Windows Outlook add-in that turns email messages and attachments into password-protected PDF files. It encrypts messages and attachments using AES-128 or AES-256. Recipients can open encrypted PDFs with a PDF viewer and password, without special software or registration. The add-in converts HTML, rich-text or text messages into formatted PDFs. Users can include encrypted attachments in a PDF, protect attachments without the message, or make PDFs from attached files. The download page lists Outlook Desktop 365, 2021, 2019, 2016 and 2013 on 32-bit or 64-bit Windows, with Windows 11 or 10,.NET Framework 4.8 or later, 4 GB RAM and 2 GB of disk space as requirements. After a 15-day trial, it reverts to a free mode limited to five encrypted PDF messages per month. Listed paid options range from $79.99 a month for one license to $3,999 a month for 100 licenses; licenses are perpetual, with maintenance and upgrades optionally renewable at 25%. The maker says email remains on the user's PC rather than being sent to the cloud.
