Pricing
Freemium: a free plan is available ("private for free & without ads"), with paid individual and business plans on a dedicated pricing page (specific plan prices not disclosed in crawled evidence).
Tuta is a privacy-focused email provider offering end-to-end encrypted email, calendar, and contacts in one product. Tuta's own homepage messaging states that the service 'guarantees your data stays private for free & without ads' and highlights 'quantum-resistant encryption' as a core differentiator. Tuta's dedicated security page documents end-to-end encryption, two-factor authentication (2FA), GDPR compliance, and ISO 27001-aligned practices as trust signals. A separate business page is headed 'Secure email to protect your business data,' indicating the product is positioned for both individual and business/team use. Tuta publishes its client-side application code as open source on GitHub, and its open-source page describes the team as 'a team of open source enthusiasts,' linking to the tutao/tutanota repository. Platform references detected across Tuta's site indicate client apps for iOS, Android, Windows, macOS, and Linux. Tuta also maintains a dedicated pricing page headed 'Create a secure email account with Tuta Mail,' confirming a structured plan lineup exists beyond the free tier, though specific plan names, features, and prices are not captured in the reviewed evidence.

Pros & Cons
Pros
Strong privacy positioning built on end-to-end encryption, GDPR compliance, and ISO 27001-aligned practices, per Tuta's own security page.
Broad platform coverage — client references found for iOS, Android, Windows, macOS, and Linux — so users are not locked into one device.
Client-side application code is open source on GitHub, giving privacy-conscious users a way to inspect how the encryption is implemented.
Offers a genuine free tier alongside paid plans, lowering the barrier to try encrypted email before paying.
Has a distinct business-focused page and messaging, suggesting the product is built to scale from individual to team/business use.
Cons
The reviewed evidence does not include specific pricing figures, storage limits, or plan-by-plan feature breakdowns, making it hard to judge value for money without visiting the pricing page directly.
No evidence of third-party integrations (e.g., external calendar sync, CRM connections, or a public API) was found in the crawled pages, which could limit fit for teams already invested in other software.
Company background details — founding year, headquarters, and team/company size — are not present in the available evidence.
