About

Agentic Inbox

Features
Read full description

Agentic Inbox is a native iPhone and iPad email client for the open-source agentic-inbox Cloudflare Worker backend. Point the app at your own Worker deployment, and your mail, credentials, and cache stay only between your device and your Cloudflare account — no third-party mail server in between. REQUIRES YOUR OWN BACKEND This is not a general-purpose client for Gmail, iCloud, or other providers. It connects exclusively to a self-hosted agentic-inbox Worker (github.com/cloudflare/agentic-inbox) that you deploy on your own Cloudflare account, authenticated with a Cloudflare Access service token. Deploy the backend first if you haven't already. FEATURES Mailboxes • List, create, switch, and delete mailboxes across your Worker's allowed domains Inbox • Threaded conversation view per folder • Pull-to-refresh and pagination • Swipe to archive or delete, with undo • Multi-select batch actions: mark read/unread, archive, delete Folders • System folders — Inbox, Sent, Drafts, Archive, Spam, Trash • Custom folders — create, rename, delete Conversations • Expandable message threads • Sanitized HTML rendering with remote-image blocking (no tracking pixels) • Star and read toggles, move to folder, attachment support Compose • New messages, reply, reply-all, forward • Drafts save locally and resume exactly where you left off Search • Search-as-you-type with filters for sender, recipient, subject, date range, read/starred status, and attachments • Removable filter chips, infinite scroll Offline • Local cache with optimistic UI, so recent mail stays readable without a connection Built for iPhone and iPad • Adaptive list-detail layout on iPad • Light and dark theme, all standard orientations PRIVACY Agentic Inbox talks only to the Worker URL you configure. Your Client ID and Client Secret are stored only on your device. No analytics, no ads, no data shared with the developer or any third party. OPEN SOURCE Agentic Inbox is open source under the Apache License 2.0.
