Temporary Email for Testing Signup and Email Flows

Testing an email flow needs a real inbox that receives real mail, and needs a new one every run. Disposable addresses fit that shape well — as long as you keep them out of your automated suites.

A workable manual QA loop

1. Generate an address and copy it.
2. Run the flow under test: registration, password reset, invitation, receipt.
3. Watch the inbox for arrival, then open the message to inspect it.
4. Check the pieces that break most often: subject line encoding, sender display name, whether the plain-text alternative exists, and whether links point at the right environment.
5. Press New address to reset state completely and run the next case.

What the viewer makes easy to check

• Plain-text fallback. If your template ships HTML only, it shows immediately.
• Link targets. The links panel lists hostnames, so a staging build pointing at production URLs is obvious at a glance.
• Encoding bugs. Mangled accents and emoji in subjects survive parsing and display as-sent.
• Attachment metadata. Filename, declared type and size are shown before you download anything.

Where to stop

Do not point CI pipelines at a public disposable service. Automated suites need deterministic addresses, retained history and an API contract, none of which a short-lived public inbox provides. Use a dedicated test-mail service or your own catch-all domain for that.
