Mailbox

Mailbox. A full mail client — folder rail, message list, reading pane, composer — where every message is a vault object you can search, link, and automate. Connect Gmail via OAuth or any IMAP/SMTP account; credentials are sealed shell-side and never touch the app.

Mailbox: Connect an accountMailbox: Connect an account
Connect an account — Mail arrives once you connect an account; until then the app holds nothing at all.
Mailbox: Bring any accountMailbox: Bring any account
Bring any account — Gmail via OAuth or plain IMAP/SMTP — either way the credentials are sealed shell-side and never touch the app.

What it can do

Section titled “What it can do”
  • Read, compose, reply, and forward; sending is idempotent, so a retry can never double-send.
  • HTML mail renders in a sandboxed frame that blocks remote images by default — tracking pixels don’t fire unless you opt in.
  • Choose a sync window from 30 days to everything, with server-authoritative flags and vault-local tags.
  • Threads, attachments as file objects, and per-message tags.
  • Other apps and the Agent can pre-seed a compose, reply, or forward through intents.
  • Senders resolve to existing Contacts people — linked, never auto-created.
