Internxt has added Mail to its lineup of privacy products, giving subscribers an end-to-end encrypted email service built directly into the company’s existing cloud storage platform. The feature is included with Internxt’s Ultimate plan, sold as a monthly or lifetime subscription, alongside the company’s Drive, VPN, Meet, Antivirus, and Photos products.
Internxt Mail uses post-quantum and zero-knowledge encryption, meaning messages are encrypted on a user’s own device before they are ever transmitted to Internxt’s servers. That structure keeps message contents inaccessible to Internxt itself, not just to outside parties.
Setting Up An Internxt Mail Account
Access to Mail requires an active Internxt account and an upgrade to the Ultimate plan, which combines storage with the company’s full suite of privacy tools. Once that plan is active, setup happens directly through a browser.
Users go to mail.internxt.com and choose a domain for their new address, with three options currently available: inxt.eu, inxt.me, and encrypt.eu. After selecting an address, users confirm their existing Internxt account password to activate the new email.
Clicking Save New Email finalizes the setup, and the account becomes ready to send and receive encrypted messages immediately, with no additional software or configuration steps required.
How Sending An Encrypted Message Works
Once an Internxt Mail address is active, sending an encrypted email involves no extra steps beyond composing and sending a normal message. Internxt describes this as a deliberate design choice, contrasting it with services such as Gmail, Outlook, or Yahoo, where sending a secure message typically requires enabling a separate confidential or encrypted mode first.
Encryption happens automatically on the sender’s device the moment a message is sent, before it ever reaches Internxt’s servers. Both the message body and any attachments are covered under the same end-to-end protection.
How It Compares To Standard Email Security
Internxt draws a direct distinction between its own zero-knowledge model and mainstream providers. According to the company, Gmail retains encryption keys on its own servers, which means Google can technically read stored messages or provide them to authorities upon request, since Gmail does not operate as a zero-knowledge service.
Gmail’s own built-in privacy option, Confidential Mode, lets users set an expiration date and an optional passcode on a message, but the feature does not provide true end-to-end encryption and still relies on Google’s standard security infrastructure. Internxt positions Mail as a stronger alternative for users who want message contents inaccessible to the provider itself.
Part Of A Broader Privacy Suite
Internxt Mail joins Internxt Send, a separate free tool for transferring encrypted files that requires no account for either sender or recipient. Files shared through Send are encrypted end-to-end, with shareable links expiring automatically after 15 days and a 100-file limit per simultaneous transfer.
The company frames Mail as the final piece completing its privacy product lineup, following the earlier rollout of Drive, VPN, Meet, Antivirus, and Photos under the same Internxt account structure. Existing Essential or Premium subscribers can upgrade to a lifetime Ultimate plan, which stacks their existing storage allowance while unlocking Mail and the rest of the Ultimate-tier features.
Current Status
As of September 2026, Internxt Mail remains available exclusively through the company’s Ultimate subscription tier, with inxt.eu, inxt.me, and encrypt.eu as the current address domain options. Internxt continues to promote the service as an open-source, post-quantum encrypted alternative to mainstream webmail providers for users seeking full control over their message privacy.
