HEY Email vs LINE

A source-aware comparison of pricing, documented capabilities and workflow fit.

Short answer

These lines are generated from the pricing we track, not from a paid placement. How we score tools.

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 LINE is

LINE is a proprietary consumer communication service for mobile and PC, offering one-to-one and group chat, media, stickers and internet voice/video calls. Core communication is free aside from network data, while stickers, region-specific Premium Backup and other services may be paid. LINE's Letter Sealing end-to-end encryption is on by default and covers text, location, supported media/files and one-to-one voice/video calls. It does not cover group voice/video calls, LINE Meetings, Albums or Notes; media/file coverage can also depend on client version and specifications. A normal group currently supports up to 500 participants.

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).

LINE: pros & cons

  • Letter Sealing is enabled by default and protects supported chat content plus one-to-one calls.
  • Text, media, location, stickers and free internet calling provide a complete consumer communication set.
  • Groups support up to 500 participants with familiar read-state and media workflows.
  • Key fingerprints let contacts verify the identity key for a protected conversation.
  • Group calls, Meetings, Albums and Notes are not protected by Letter Sealing and use transport encryption instead.
  • Photo, video, voice-message and file encryption can depend on app version and specifications.
  • Account transfer can make older Letter-Sealed messages unavailable, making backup and recovery planning important.
  • Regional availability differs for OpenChat, premium backup, payments and related ecosystem services.

Our verdict on HEY Email

The most innovative and peaceful way to handle email in the 21st century.

Our verdict on LINE

LINE is a capable consumer messenger with meaningful default E2EE, but Letter Sealing is not universal. Check the protection indicator and fingerprints for important chats, keep group calls and shared Albums/Notes outside sensitive workflows, and test account transfer before relying on history continuity.
