What is iPosta?

iPosta is a native macOS email client built entirely with Swift and SwiftUI. It connects your Google and Microsoft email accounts in one unified inbox — no Electron, no web views, no compromises.

Which email providers are supported?

Gmail (Google Workspace included) and Microsoft 365 / Outlook.com. More providers are planned.

Is iPosta free?

Pricing details will be announced soon. You can download the latest DMG directly from our website.

Where are my emails stored?

Locally on your Mac, in an SQLite database inside the app's sandbox container. Nothing is sent to our servers — because we don't have any.

Can I use multiple accounts?

Yes. Add as many Google and Microsoft accounts as you need. The unified inbox shows messages from all accounts sorted by date.

Does iPosta collect my data?

No. iPosta does not include any analytics, crash reporters, or tracking of any kind. All your email data stays locally on your Mac. We do not operate servers that store or process your emails.

How does iPosta handle authentication?

iPosta uses industry-standard OAuth 2.0 for both Gmail and Microsoft 365 — your email provider passwords are never stored in the app. OAuth tokens are stored securely in the macOS Keychain.

Does iPosta support attachments?

Yes. Download, preview with Quick Look, open in default app, or save to any location. You can also download all attachments at once.

What happens when I'm offline?

You can read all synced emails, search, and compose. Any actions you take (read, delete, move, flag, send) are queued with automatic retry and executed when the connection is restored.

Does iPosta support dark mode?

Yes. System, light, and dark appearance modes. Email content can be independently toggled between dark and original styling.

What macOS version is required?

iPosta requires macOS 14.6 (Sonoma) or later.

Is there an iOS/iPhone version?

Not yet. iPosta is macOS-only for now.
