Temporary email for developers and QA
A disposable inbox is a quick way to see your own app’s emails the way a new user would. Here is what it is good for, and where you need something else.
Good for manual testing
- Walking through your sign-up flow as a brand-new user, without reusing your own address.
- Checking that confirmation and password-reset emails arrive, and how quickly.
- Seeing how your HTML email renders when remote images are blocked, which is common in real email apps.
- Checking that your links, codes, and unsubscribe links work.
- Testing what happens when your app emails an address that has stopped existing.
What you’ll see in our inbox
We show the cleaned message: scripts stripped, remote images blocked until you load them, and attachments removed. That is close to a strict real-world email client, which is useful, but it means you can’t test attachments here.
Deliverability hints
If your email reaches a temporary inbox but not Gmail or Outlook, the problem is often authentication. Make sure your sending domain has SPF, DKIM, and DMARC set up, and that the “From” domain matches them.
Not for automated tests
TempMailyo has no public API, and the bot check and rate limits are there to stop scripts from creating inboxes. For automated end-to-end tests, use a tool built for that job:
- A local mail catcher, such as Mailpit, for development environments.
- A catch-all mailbox on a domain you own, for staging environments.
- The test or sandbox mode of your email sending provider.
These are faster, don’t depend on a third party’s domains being accepted, and keep test data under your control.
