Platform

The platform behind
the email client.

maiLane is more than a UI. Under the hood, it's a composable platform for inboxes, routing, identity, and observability — so the client your team uses every day is also the substrate your business runs on.

The client

A fast, keyboard-first email client your team opens every morning — threads, search, snooze, send-later, and the shortcuts you'd expect.

Routing layer

A declarative engine for assigning, forwarding, transforming, and dispatching mail to webhooks. Versioned, previewable, and observable.

Identity layer

Workspace, team, and inbox-level access tied to your IdP. Roles, scopes, and audit trails for every action — built in, not bolted on.

Under the hood

Composable primitives. Reasonable defaults.

The client is one surface on top of a deeper platform. The same primitives that power the inbox are exposed through APIs and configuration — so admins, operators, and developers all reach for the same building blocks.

Workspaces & domains

Multi-tenant by design. Domains belong to a workspace, with isolated routing, policies, and observability per workspace boundary.

Routing graph

Rules are typed, validated, and versioned. Promote changes through dev → staging → prod with dry-run preview against historic mail.

Policy engine

Encode retention, MFA, sharing, and access constraints as policies — applied automatically when inboxes and users are created.

Observability

Every action emits a structured event. Stream to S3, Datadog, Splunk, or your warehouse with no rate limits.

Public API & webhooks

REST API with idempotent operations, OpenAPI spec, and signed webhooks. Generate ergonomic SDKs from the contract.

Standards-first

IMAP, SMTP, SPF, DKIM, DMARC, ARC, and TLS-RPT — all implemented to spec. No proprietary client required.

Use cases

Built for the way real teams work.

Daily email client

The fast, focused inbox your team opens every morning.

Shared workflows

Run support, billing, and ops queues without leaving the client.

Operations teams

Triage, assign, and route — all from inside the same app.

Distributed teams

SSO, time-zone aware SLAs, and async-friendly internal notes.

Multi-domain orgs

Operate dozens of brands and domains from a single workspace.

Client-facing comms

Per-client routing, branded signatures, and clean audit trails.

Internal support

People ops, IT helpdesk, and finance queues — without buying another tool.

Partner channels

External communication with policy boundaries and full lineage.

Developer experience

An API designed to be read.

Resources are predictable. Errors are typed. Idempotency keys are first-class.

POST api.mailane.net / v1 / inboxes
