HEY Email vs Threema

What HEY Email is

HEY is a revolutionary email service from the creators of Basecamp that aims to fix everything wrong with modern email. It replaces the traditional inbox with the 'Imbox'—a place for things that actually matter. With its unique 'Screening' feature, YOU decide who is allowed to email you. HEY blocks all spy trackers, protects your privacy, and offers innovative features like 'The Feed' for newsletters and 'The Paper Trail' for receipts. It's a premium, opinionated take on email for people who want to reclaim their focus and sanity.

What Threema is

Threema is a Swiss secure-messaging family rather than one subscription. Threema Private is a consumer mobile app that can be purchased directly for Android for a current one-time price of $7.49, €6.49 or CHF 5.99 and can create an identity without supplying a phone number or email. Threema Work adds annual per-user licensing, a management cockpit, app configuration, optional Broadcast and Gateway components, and a 30-day trial for up to 30 users. Threema Gateway is a separate credit-based API integration. Apps are open source and communications use end-to-end plus transport encryption, but server code and the operating environment are separate trust and audit scopes.

Choose HEY Email if

• Privacy Seekers and Busy Professionals who hate email.

Choose Threema if

• Individuals wanting a paid messenger without mandatory phone-number identity
• Organizations centrally configuring encrypted mobile communication through Threema Work
• Systems sending transactional Threema messages through a deliberately selected Gateway encryption mode

Skip Threema if

• A free consumer messenger with a large existing contact network is the priority
• Enterprise selection is based on the consumer one-time price
• Identity lifecycle, device backup, administrator visibility, Gateway keys and annual renewal have not been tested

HEY Email: pros & cons

• Total Privacy: Automatically blocks all tracking pixels used by marketers.
• Screening: No more spam or unwanted emails ever—you approve every new sender.
• Aesthetic UI: A completely fresh, modern take on what an email app looks like.
• Productivity: Features like 'Reply Later' and 'Set Aside' keep your inbox clean.
• Subscription Only: There is no free version of HEY; it is a premium service.
• No Folders: It uses a specific organization system that might be jarring at first.
• Locked Domain: Requires using an @hey.com address (unless you use the more expensive custom domain plan).

Threema: pros & cons

• Messages, calls and files use end-to-end encryption with keys tied to a randomly generated Threema ID.
• Consumer identity can be created without making a phone number or email mandatory.
• Open-source apps and published security material provide inspectable implementation evidence.
• Threema Work adds centralized configuration and deployment, while Gateway supports programmatic messages.
• Private, Work, Broadcast, Gateway and OnPrem have different licensing, administration and deployment boundaries.
• The $7.49 figure is a direct Android consumer license, not a Threema Work enterprise seat or iOS universal price.
• Work contracts are annual, prepaid and auto-renew unless cancelled at least 90 days before term end.
• Gateway Basic mode lets the server handle encryption and private keys; true E2E mode requires correct client-side key operations.
