SyncMailz — your mail, on your device

A lightweight mailbox for people and their authorized agents.

SyncMailz connects Gmail and Outlook accounts through Google and Microsoft sign-in. Read messages and attachments, search mail, compose and send messages, save local drafts, and organize mail with read status, archive, spam and trash actions.

Local-first by design

The mailbox application runs on your computer. Google and Microsoft handle sign-in; authorization is stored using operating-system protection. This website does not provide access to your mailbox.

One mailbox, several ways to work

Use the local interface or explicitly authorize an agent through the CLI, local API or MCP. The same mailbox operations serve each interface.
