Email Collaboration Platform

Part of the worlds-biggest-software-project initiative.

An open-source, AI-native shared inbox with built-in SLA tracking and email workflow automation — a Frontapp alternative for teams who want privacy, self-hosting, and intelligent automation without the per-seat tax.

Email Collaboration Platform is a shared inbox and team email workflow system designed for support, customer success, and operations teams who manage shared aliases like support@, billing@, or info@. It targets organizations frustrated by rising SaaS prices, unbundled AI add-ons, and the lack of a credible open-source option in a category dominated by proprietary vendors.

Why Email Collaboration Platform?

No strong open-source incumbent. The shared inbox market is dominated by SaaS-only tools (Front, Hiver, Missive, Help Scout, Zendesk, Freshdesk, Intercom, Gmelius, HappyFox, Pylon). There is no widely adopted open-source shared inbox.
Pricing pressure is rising. Front raised prices in late 2025 and unbundled AI features as paid add-ons. Zendesk Suite Team starts at $55/agent/month, Hiver Enterprise at $105/user/month, Intercom Essential at ~$39/seat/month — costs that compound quickly at scale.
Privacy and self-hosting are unmet needs. Legal, government, and healthcare buyers regularly need data residency, retention control, and self-hosted deployment that the major SaaS vendors do not offer.
AI features are bolted on, not native. Incumbents added AI as a premium tier on top of rule-based engines. An AI-native architecture can deliver intelligent triage, drafting, and SLA prediction as core behaviour, not an upsell.
Email-first teams are underserved. Many platforms (Intercom in particular) optimise for live chat. Teams whose primary channel is async email need a tool built around that workflow.

AI-Native Advantage

Where incumbents bolt AI onto rule-based engines, this project treats AI as the default substrate. Capabilities include intelligent SLA prediction (analysing email content, sender history, and context to forecast breach risk before it occurs), contextual reply drafting that uses full thread and CRM history, sentiment-driven escalation that auto-routes frustrated customers in real time, and inbox-zero automation where AI agents fully resolve common inquiries (status checks, password resets, FAQ) end-to-end. Cross-channel conversation stitching links the same customer's email, chat, and SMS threads automatically — a task today handled by manual tagging.

Tech Stack & Deployment

The platform is designed for both self-hosted and cloud deployment, with a privacy-first stance suited to legal, healthcare, and government buyers. Email connectivity targets open standards: IMAP/SMTP for broad compatibility, JMAP (RFC 8620) for modern push-based sync, and OAuth 2.0 / XOAUTH2 for Google Workspace and Microsoft 365. Outlook/Exchange access uses Microsoft Graph API. SLA policies follow the ITIL v4 framework. GDPR and CCPA compliance, including data residency and retention controls, are first-class concerns.

Market Context

The global shared inbox software market was valued at approximately $1.89 billion in 2025 and is projected to reach $5.5 billion by 2035 at a 12–14% CAGR (Virtue Market Research, 2025; Micro Market Insights, 2025). Entry-level plans run $10–$25/user/month, mid-market $25–$65, and enterprise plans frequently exceed $100/user/month with custom quotes. Primary buyers are customer support managers at SMBs, VPs of Customer Success at mid-market SaaS companies, IT/operations teams managing shared aliases, and high-volume e-commerce brands.

Contributing

We welcome contributions from developers, domain experts, and potential users. See CONTRIBUTING.md for guidelines.

Important: All contributions must be your own original work or clearly attributed open-source material with a compatible licence. Copyright infringement and licence violations will not be tolerated and will result in immediate removal of the offending contribution. If you are unsure whether a piece of code, text, or other material is safe to contribute, open an issue and ask before submitting.

Note: Zendesk and other established help desk vendors likely hold active patents on SLA management and automated escalation. Real-time co-drafting and collision detection may also be patent-encumbered. Independent legal review is recommended before implementing similar capabilities.
