Pricing verified 2026-05-19 — source: mailosaur.com/pricing. Mailosaur's OTP/Authenticator inclusion is ambiguous on the public pricing page — verify before relying on "OTP included" claims. Inboxical's extractCode() ships on every paid tier.
Same test, both tools
Nearly identical developer experience. The main difference is what you pay for it.
Inboxical
// Inboxical — Playwright test
import { test, expect } from '@playwright/test'
import { createInbox, waitForMessage } from '@inboxical/playwright'
test('welcome email', async ({ page }) => {
const inbox = await createInbox()
await page.goto('/register')
await page.fill('[name=email]', inbox.email_address)
await page.click('[type=submit]')
// Long-polls until email arrives
const [msg] = await waitForMessage(inbox.id)
expect(msg.subject).toBe('Welcome!')
})
Mailosaur
// Mailosaur — Playwright test
import { test, expect } from '@playwright/test'
import Mailosaur from 'mailosaur'
const client = new Mailosaur('YOUR_API_KEY')
test('welcome email', async ({ page }) => {
const serverId = 'YOUR_SERVER_ID'
const email = `test@${serverId}.mailosaur.net`
await page.goto('/register')
await page.fill('[name=email]', email)
await page.click('[type=submit]')
// Poll-based wait (no long-polling)
const msg = await client.messages.get(serverId, {
sentTo: email
})
expect(msg.subject).toBe('Welcome!')
})
