Address and emails are deleted when it expires
Keep each signup, password reset, and OTP check in its own disposable address. When the test is done, move on without leaving a trace.
Choose the right way to receive email
Teams use all three approaches, each for different situations. Choose based on how long you need to keep the test email, and you’ll usually get it right.
We do three things well
From getting an address to waiting for the email and moving on. We spell out the trade-offs so you can decide if it’s right for you.
Page opened · Address generated
No signup or personal details required
No signup or login needed. Your address is ready when the page loads—copy it straight into a staging form.
Trade-off: The address isn't tied to your identity, which makes it useful for testing but unsuitable as a long-term contact address.
Your inbox refreshes automatically, and new emails usually appear within seconds. If other services receive mail promptly but yours doesn’t, the issue is likely on the sending side.
Trade-off: We only receive email. We can help you work out which side has the issue, but we can’t resend or recover messages for you.
One address, one timeline
Most OTP tests take just a few minutes. For a full day of regression testing, extend the address—up to 24 hours total.
Trade-off: When it expires, the address and emails are deleted together and can’t be recovered. Don’t use it to register accounts you’ll need long term.
For email you need to keep
Disposable addresses last up to 24 hours. For test accounts or vendor notifications you need to keep, an alias is a better fit.
How it works
Keep your test script as it is—just use a fresh email address for each run.
Open the homepage to generate a new address, then click “Copy” to put it on your clipboard.
Paste it into a signup or password reset form and submit to trigger an email from your system.
Your inbox refreshes automatically, and emails usually arrive within seconds. The message is rendered as HTML so you can check the template, too.
For the next run, click “Get a new address” to start a new case. The old address and its emails are deleted when it expires.
