End-to-end email encryption is getting more attention as security and compliance concerns mount, but practical use cases are rapidly being eaten away by other technologies.

Non-email alternatives
One potentially useful purpose for end-to-end encrypted email is for doctors, banks, and lawyers to send sensitive documents to their customers. Sending these files through ordinary email is a security risk, but also a compliance violation in many regulated industries. Often, getting those users to sign up for an encrypted email service is a non-starter.
Instead, institutions typically used third-party file sharing solutions. One of the most popular services for documents that need signatures is DocuSign. The company claims more than 300,000 business customers, and over 200 million users in 188 countries. Recipients get an email with a link to the DocuSign website, where they authenticate themselves, and can then easily read and sign documents. DocuSign meets the legal requirements of the U.S. Esign Act, as well as similar laws in other countries, and the company claims that it’s signatures have never been successfully repudiated or challenged in any court anywhere in the world.
