Postbird on Mac
Native desktop builds for macOS — install once, run offline, no browser tab or subscription required.
Setup on Mac
Download the installer
Download the latest Postbird installer from the GitHub Releases page (https://github.com/bensblueprints/postbird-mvp/releases) — or build it yourself from the MIT source.
Install
Run the installer — one click, no terminal, no account to create.
Run it locally
Postbird runs 100% on your machine — no account, no telemetry, and it keeps working with the Wi-Fi off.
What works offline: everything. Postbird is a desktop app — once it's installed, no feature needs a connection to us.
Postbird on Mac — honest answers
Is it really free on GitHub?
Yes — MIT source at github.com/bensblueprints/postbird-mvp, always. $149 buys the packaged installer, 1-click setup and updates — and funds the open-source version.
Is it actually CAN-SPAM / GDPR compliant?
The legal minimums are enforced in code, not suggested: the server returns a 400 if you try to send without a physical address configured, the compiler appends an unsubscribe footer if a template lacks one, and every email carries RFC 8058 one-click unsubscribe headers — which Gmail and Yahoo require for bulk senders.
