Inboxical Documentation

Email testing infrastructure for developers. Create isolated inboxes, verify delivery via REST API.

What is Inboxical?

Inboxical is a cloud-hosted email testing API. Instead of configuring a local SMTP server or sharing a test inbox with your team, you create isolated inboxes on demand — one per test case — and assert email delivery through a clean REST API.

// Create an inbox
const inbox = await api.post('/inboxes')
// → { id: "ix_3f9a", address: "[email protected]" }

// Trigger your app
await myApp.register({ email: inbox.address })

// Assert the email arrived
const [msg] = await api.get(`/inboxes/${inbox.id}/messages`)
expect(msg.subject).toBe('Welcome to MyApp!')
