Once in, they'll have a lot of friction keeping them with Proton, reducing the churn Proton might see with any individual service. Proton also benefits by creating its own privacy-by-default ecosystem that it can usher customers into. “Evolving into a unified Proton reflects our growth from an end-to-end encrypted email provider to an entire privacy ecosystem, allowing us to deliver even more benefits to the Proton community and make privacy accessible to everyone,” Proton founder and CEO Andy Yen wrote in the announcement. Since passwords are an outdated, easily crackable security measure that we're more or less stuck with for now, that's already a bonus. Proton has multiple services, and now they'll be available with one account login - this reduces the potential entry points for a phishing attack on a business or individual, and cuts down on the number of passwords everyone needs to remember. Users will get 500 GB total storage, 15 email addresses, support for three custom email domains, and unlimited folders, labels, messages, and filters, as well as access to Proton Calendar, Proton Drive (still in beta), and Proton VPN. Then there's the bundle, Proton Unlimited, at $11.99/month when billed monthly, $9.99/month when billed annually, and $7.99/month when billed for two years. Proton will keep Mail Plus, the non-bundled email service, available for $4.99/month when billed monthly, $3.99/month when billed annually, and $3.49/month when billed for two years at a time.

Proton Free costs nothing, but is limited: Users get up to 1 GB total storage, a single email address, 3 folders and labels, and the ability to field 150 messages per day. The service now offers three plans for its email, one of which includes the bundle of additional services - the only other stand-alone plan that will still be offered without a bundle is the VPN, where the price remains unchanged for now. The services will all be integrated, with one account connecting them all, similarly to large communications software systems like Google Workspace or Microsoft Teams. ProtonMail - sorry, Proton - is changing its name, which means a new logo, interfaces, apps, and website domain.
