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 Viber is
Rakuten Viber is a phone-number-based consumer messaging and calling service for mobile, desktop and tablet. Core app-to-app messaging and calling are free, while Viber Out uses purchased credit or automatically renewing monthly plans to call ordinary mobile and landline numbers. One-to-one chats, ordinary groups and one-to-one voice/video calls use end-to-end encryption on current clients. That protection does not extend to Communities, Channels, bot chats, group voice/video calls or paid Viber Out calls, which have different participant and delivery models. Viber also warns that Viber Out connectivity issues may occur in Turkey and several other countries.

- Viber Out provides a paid route to mobile and landline numbers that do not use Viber.
- Communities, Channels, bots, group calls and Viber Out calls are not end-to-end encrypted.
- Viber Out requires credit or a monthly auto-renewing plan, and country, destination and number-type exclusions apply.

Our verdict on HEY Email
The most innovative and peaceful way to handle email in the 21st century.
Our verdict on Viber
Viber is a capable consumer messenger where its network is already present, but its encryption claim has boundaries. Distinguish ordinary encrypted chats from Communities, Channels, bots, group calls and Viber Out, and never rely on a paid calling plan until the destination rate, renewal and local connectivity are tested.
