grey8
Early build for Linux

Mail, calendar and contacts in one quiet window.

grey8 Mail brings your mail, calendar and contacts from Google, Microsoft, Proton and any IMAP server into one native Linux app. It keeps a copy on your computer, so it opens instantly and keeps working offline.

Your inbox, with a conversation open.

One inbox for every account

Sign in with Google, Microsoft or Proton, or add any IMAP and SMTP server. Switch between accounts from the rail on the left, or look at all of them at once. Mail, calendar and contacts follow the account you pick.

A conversation with three messages, the older ones collapsed into one line each.
Long threads fold up so the newest message is the first thing you read.

Write the way you mean to

A real rich-text editor: bold, italic, underline, lists, quotes, links, text colour and size, and tables. Signatures can be formatted too, and every message has a plain-text version made for you. Prefer plain text? Switch with one click.

Lists, colour, size and tables, with a plain-text copy made for you.

Your calendar, next to your mail

Day, week, month and agenda views across every account, each calendar in its own colour. Invitations in your mail show up as a card with Yes, Maybe and No. Pick the first day of the week, show week numbers and set a default reminder.

Contacts that stay in sync

Your address books from Google, Microsoft and Proton, searchable and sorted the way you like. Start a message or a meeting from a contact.

Keyboard first, never keyboard only

Single-key shortcuts in the message list: archive, delete, star, reply, move to any folder. Choose the grey8 set or a Gmail-style set, and change any key. Press Ctrl+K for a command palette that finds every action by name.

Also

Private by default

Pictures in messages stay blocked until you allow them, once or always for a sender. New-mail notifications show only who it is from unless you ask for more. Proton mail is unlocked on your computer. Changes you make offline are kept and sent when you are back online, and Undo is there for archive, delete and move.

Built for big mailboxes

The conversation list loads in a blink, even with hundreds of thousands of messages on disk. A disk limit per account removes the oldest mail from your computer, never from the server.
