Unfortunately, the majority of email is neither private nor secure. Emails are sent and received using human-readable text, and most email providers don’t use encryption to protect the contents. Plus, messages hop between multiple email services, domains, and servers—and each can retain a copy of your message. Because of this, a message—including its attachments—can exist in several places at once and easily be intercepted by malicious third parties. This is one of the main reasons we created illumy: to provide secure, private email service with a modern and media-rich persistent messaging experience.
