Signup & onboarding tests
Register a fresh user in every E2E run with a real, unique inbox — no shared test accounts, no flaky cleanup.
Email API for QA & test automation
Disposable inboxes
for your test suite.
Create a throwaway mailbox in one call, then waitForMessage() blocks until the
verification email lands so you can assert on the code — no polling, no flake. Real-time,
server-to-server. Webhooks too, if you'd rather push.

Give your AI agent an inbox.
Connect Claude, Cursor or VS Code to tempy.email. Your agent can create a disposable address, sign up with it, wait for the verification email and read back the code on its own.
“Sign up on staging.myapp.com with a fresh inbox and tell me if the verification email arrives.”
- In Claude, open Settings → Connectors → Add custom connector. Name it
tempy email, paste the URL below and click Continue. - Under Authentication pick Sign in now, and under OAuth client pick Register automatically (Claude detects both), then click Add.
- Sign in to tempy.email and click Allow. No API key needed.
https://api.tempy.email/mcpBuilt for test automation
Every flow that sends an email — testable.
Email verification & OTP
waitForMessage() blocks until the confirmation email or one-time code lands, then hands it to you to assert on — right in your test.
Password-reset flows
Trigger a reset, waitForMessage() for it, follow the link — the whole loop, automated, no sleep() in sight.
Deliverability & webhooks
Prefer push? Point a webhook at your ingest endpoint and get every message as JSON. Your call — wait or webhook.
Why teams pick tempy
The disposable-email tools you know, with a real API.
One call, no flake
waitForMessage() blocks until the email arrives and returns it — or fails deterministically on timeout. No poll loops to hand-roll.
Real-time delivery
Mail is visible in milliseconds — no “wait 30s and retry”.
Choose the address
Deterministic local parts for stable, collision-free test fixtures.
Send & reply
Reply to a message from the API to test two-way flows.
Webhooks too
Have a public ingest endpoint? Get every message pushed as JSON instead.
