How email evolved from an academic tool to a surveillance economy ā and why 100 million people are switching to encrypted alternatives.
Email is older than the web itself. What started as a simple messaging protocol between researchers has become the backbone of digital identity ā your email address is your passport to the internet. But for most of its history, email was never designed to be private. Here's how we got here, and where we're going.
Email predates the World Wide Web. The first networked email was sent in 1971 by Ray Tomlinson over ARPANET, using the now-iconic @ symbol to separate user from host. Throughout the 1980s, email was used primarily by academics, government researchers, and early tech companies ā people who had access to networked computers.
In 1996, everything changed. Hotmail launched as one of the first free web-based email services, co-founded by Sabeer Bhatia and Jack Smith. The name "Hotmail" was chosen to include the letters HTML ā a nod to the web. Within 18 months, Microsoft acquired it for an estimated $400 million and rebranded it as MSN Hotmail.

First major free webmail service. "Get your free email at Hotmail" becomes the original viral marketing campaign.
Google launches Gmail on April 1 with 1GB of storage ā 500x what competitors offered. Many thought it was an April Fools' joke.
Edward Snowden leaks reveal mass surveillance programs. The world learns that email is not private. Public trust in tech companies collapses.
Founded by CERN scientists in Switzerland, Proton Mail becomes the world's first encrypted email service with zero-access architecture.
When Google launched Gmail in 2004 with an unprecedented 1GB of free storage, it was revolutionary. But the business model was clear from the start: Gmail scans your emails to serve targeted ads. The famous tagline "Don't be evil" was tested almost immediately.
By 2012, Gmail had over 425 million active users. Combined with Yahoo Mail and Outlook (formerly Hotmail), the "big three" controlled over 90% of consumer email. The trade-off was invisible to most users: in exchange for free email, Google, Microsoft, and Yahoo collected vast amounts of behavioral data ā not just for ads, but increasingly for AI training.
As one former Google executive put it: "If you're not paying for the product, you are the product."
In June 2013, The Guardian and The Washington Post published the first stories based on Edward Snowden's leaked NSA documents. The revelations were staggering: the US government, through programs like PRISM, had been collecting email data, chat logs, and browsing history from major tech companies ā often without individual warrants.
Public trust in digital privacy evaporated. According to a Pew Research study, 87% of Americans took steps to be less visible online in the months following the Snowden revelations. The question shifted from "Do I have anything to hide?" to "Why should anyone have access to my private conversations?"
Proton Mail is end-to-end encrypted, based in Switzerland, and free to start. No ads. No scanning. No surveillance.

Proton Mail launched in 2014, founded by Andy Yen, Jason Stockman, and Wei Sun ā scientists who met at CERN. Their premise was simple but radical: build an email service where not even the provider can read your messages.
Proton's zero-access encryption means emails are encrypted on your device before they ever reach Proton's servers. Even if a government demanded access, Proton simply doesn't have the keys. This is fundamentally different from Gmail or Outlook, where Google and Microsoft hold the encryption keys and can access your data.
Switzerland was chosen deliberately. Swiss privacy laws are among the strongest in the world. Data stored in Switzerland is protected under the Swiss Federal Data Protection Act, which is stricter than GDPR and far stronger than US privacy law.
By 2026, Proton Mail has grown to over 100 million users worldwide. The service has expanded beyond email to include Proton VPN, Proton Drive (encrypted cloud storage), Proton Calendar, and Proton Pass (password manager).
The shift is unmistakable: privacy is no longer a niche concern. GDPR in Europe, CCPA in California, and a wave of data breach scandals have made encryption a mainstream expectation. Businesses are increasingly choosing encrypted email not just for security, but as a competitive advantage ā "we protect your data" is a selling point.
The history of webmail is the history of a bargain most of us didn't know we were making. Free email in exchange for our data. But that bargain is being rewritten. Encrypted email ā once the domain of security experts ā is now available to everyone, for free.
Your email address is the key to your digital life. It's tied to your bank, your social media, your healthcare, your work. Shouldn't it be private?
