What it does

A few things, done properly, instead of forty done badly.

Threads read like a conversation

No quoted-reply archaeology. Every message in a thread is a bubble, newest at the bottom, and the reply field is docked right under it.

Can you make Thursday 3pm instead?
Thursday works. Sending a new invite.
⌘↩ sent · 2:14 pm
Everything, in one search field

⌘K searches every account and folder at once — senders, subjects, message text and attachment names. It works offline, because your mail is already on your Mac.

Every account, one window

Gmail, iCloud, Outlook, Microsoft 365, Yahoo or any IMAP server, in one unified inbox where you can still tell where mail came from — every avatar carries its account's colour ring, every account its own unread count.

Send later, even with the app closed

Schedule a message for tomorrow 8am or any date you pick. It leaves on time even if bytemail isn't running — a small helper on your Mac sends it, not a server of ours.

✓ Scheduled Sends tomorrow at 8:00 — app open or not
Sign in with Google or Microsoft In your browser, on their page. bytemail never sees your password — only a revocable token, kept in the macOS Keychain.
Mail arrives when it arrives Push over IMAP IDLE, native notifications, and an unread badge on the Dock icon. A catch-up sync after sleep or a network change.
Designed mail, rendered as sent Newsletters and receipts keep their layout — with scripts off, and remote images blocked until you press Load Images.
A real writing surface Bold, italic, lists and text sizes, attachments by drag and drop, drafts saved as you type.
Smart tabs All, Primary, Updates and Promos, sorted on your Mac, each with its own unread count — plus an unread-only switch.
Real sender pictures Photos from your Mac's Contacts and brand icons from senders' own sites, with initials as the fallback.
Why native matters

An Electron mail app can't blur your wallpaper.

bytemail is SwiftUI and AppKit. No bundled browser engine, no web views pretending to be windows — real macOS materials, the system Keychain, native notifications, and an app that's a few megabytes instead of a few hundred.
