Tuta Mail

Tuta Mail is a privacy-focused email service with an encrypted calendar and apps for desktop and mobile. It is best suited to people willing to use Tuta’s own apps or browser rather than a conventional mail client. Its free tier is a low-commitment way to start, while paid plans make more sense for people who need storage, custom domains or shared calendars.

Overview

End-to-end encrypted email and an encrypted calendar form the core of Tuta. Its clients are open source and auditable, and the service uses quantum-resistant cryptography. Data is stored on Tuta servers in ISO 27001-certified data centers in Germany; the company is based in Hanover and was founded in 2011.

The key compromise is the absence of mail protocol support. If connecting an existing mail client through a mail protocol is essential, Tuta is not the right choice. Its own apps and browser access cover Android, iOS, Windows, macOS and Linux, and paid plans include offline support.

Key features

Encrypted email and calendar

Tuta combines end-to-end encrypted mail with an encrypted calendar. Free users get one calendar; paid plans provide unlimited calendars, sharing and event invitations. Invitations to people outside Tuta can optionally be encrypted with a shared password. That makes paid plans more suitable for people coordinating schedules, while the free calendar is enough for a basic personal setup.

Storage, aliases and domains

The free plan’s 1 GB is a useful starting allowance, but it leaves little room for a growing mailbox. Revolutionary raises storage to 20 GB and includes 15 extra email addresses and three custom domains. Legend expands that to 500 GB, 30 extra addresses and 10 custom domains. Both paid plans support custom email domains; the extra capacity and address options make Legend the stronger fit for heavier users, while Revolutionary covers more modest needs.

Desktop clients can import EML or MBOX files, which helps when moving existing mail into Tuta. The service also supports offline use, with full offline support among paid-plan benefits.

Pricing

Tuta uses a freemium model. The Free plan costs nothing, billed billed annually, and is described as forever free. It includes 1 GB storage, one calendar, three labels and end-to-end encryption. It suits personal use with light storage needs, but lacks the custom domains and expanded calendar features of paid plans.

Revolutionary costs €3 a month, billed billed annually. It includes 20 GB storage, 15 extra email addresses, three custom domains, unlimited calendars and offline support. It is the practical upgrade for individuals who need a domain or more room without moving to the largest tier.

Legend costs €8 a month, billed billed annually. Its 500 GB storage, 30 extra addresses, 10 custom domains, unlimited calendars and priority email support suit people with substantial storage or support needs. Priority email support replies within one business day.

Paid plans can add family multi-user support through support. Revolutionary family members cost €3 per user per month and shared mailboxes cost €3 per month; Legend family members cost €8 per user per month and shared mailboxes cost €8 per month. These charges matter for households sharing the service: per-user and shared-mailbox costs add to the plan price.

Platforms

Apps are available for Android, iOS, Windows, macOS and Linux, with browser access as well. This broad coverage makes Tuta workable across common phone and computer platforms, but the lack of mail protocol support means users cannot rely on a conventional mail client connection.

Who it's for

Tuta is a strong fit for privacy-conscious individuals who want encrypted mail and calendar data, open-source clients, and the option to use custom domains. The free plan suits light personal use; Revolutionary fits users who need a domain, aliases and more storage; Legend is for larger storage requirements or expanded family use. People who need standard mail protocol support should choose another service.

Pros and cons

• Pros: End-to-end encrypted email and calendar, with quantum-resistant cryptography, make privacy central rather than an add-on.
• Pros: Open-source clients and availability across mobile, desktop and browser give users multiple ways to access Tuta within its own ecosystem.
• Pros: Paid plans scale from 20 GB to 500 GB and add custom domains, aliases and calendar sharing.
• Cons: No mail protocol support rules out users who need a conventional mail client connection.
• Cons: The free plan’s 1 GB storage and single calendar are limited for larger mailboxes or shared scheduling.
• Cons: Paid prices are annual-billed, and family members and shared mailboxes carry additional monthly charges.

Verdict

Choose Tuta Mail if encrypted email and calendar features, open-source clients and custom-domain options matter more than connecting through a standard mail protocol. The free tier offers a sensible starting point, but its 1 GB cap is modest; Revolutionary is the balanced paid choice for added storage and domains, while Legend is for substantially larger needs. Look elsewhere if your preferred mail client depends on protocol support.
