InboxCNX organization overview dashboard

Email integrations shouldn't feel like rebuilding infrastructure.

Problem

Email integrations are still painful.

Messy IMAP / OAuth flows and provider-specific auth quirks.
Different provider behaviors (Gmail, Outlook, generic IMAP…).
No consistent, normalized structure for messages, threads, labels.
Fragile parsing, threading & state handling you have to maintain.
Compliance, security & auditing overhead on your side.

Developers shouldn't have to rebuild email infrastructure to interact with them.

Solution

InboxCNX fixes this.

Unified API for all inboxes → abstracted away from provider quirks.
Clean, normalized email model for messages, threads & metadata.
Secure OAuth-based connection flow managed by InboxCNX.
Webhooks & events for incoming mail with structured schemas.
Optimized for incoming email → not another generic SMTP provider.

Built For Two Worlds

Direct Integration

For Business & Internal Systems

Connect company-owned or team-managed inboxes and use InboxCNX as a clean, reliable data layer inside your product or internal tools. Perfect for workflows where email is part of the operational backbone — across automation, analytics, finance, support, or custom integrations.

Connect shared or individual company inboxes
Centralized account management & unified authentication
Consistent structured email data across all providers
Automation-ready foundation for workflows, dashboards & internal apps

White-Label Integration

For SaaS & Developer Platforms

Let your users connect their own inboxes. InboxCNX handles syncing, parsing, and normalization behind the scenes, while each mailbox remains fully isolated and scoped to that individual user — ensuring clean multi-tenant boundaries for SaaS products, AI tools, and workflow platforms.

End users connect their personal or work inbox securely
Each mailbox is private, isolated and scoped to that user only
No cross-account visibility — multi-tenant by design
InboxCNX operates as your behind-the-scenes email infrastructure

Both modes, one control plane

InboxCNX mailbox connections across Direct and Whitelabel modes

Two Processing Modes

Inbox Pipeline

For real-time processing

A lightweight mode for apps that only need to react to incoming email. InboxCNX processes and normalizes messages instantly, then pushes clean data to your API or webhooks — without storing anything unless you explicitly enable it.

Real-time ingestion of incoming email
Normalized payloads delivered via API or webhooks
Ideal for workflows, automations, rules, and AI pipelines
Zero storage by default → minimal footprint, instant response

Inbox Storage

For full inbox access & persistent data

A persistent mode for products that need to work with email, not just react to it. InboxCNX stores normalized messages so your app can search, filter, tag, analyze, and interact with an inbox like a structured database.

Processed emails are stored and fully accessible via API
Search, filter, query, tag & manage messages across history
Stable metadata, thread context & attachment handling
Perfect for SaaS dashboards, AI agents, CRM/finance tools & compliance needs
