Will you be done in minutes?
Temporary email works well for one-time verification codes, trial sign-ups, and quick checks—no login needed.
Choose an address for your use case
Temporary email or an email alias?
Both keep your personal email separate from the address you share, but they handle incoming messages differently. Temporary email delivers messages to a web inbox and expires; aliases forward messages to an email address you’ve verified. Start with when your task will be finished, then choose your address.
Start by checking one thing
Need to receive messages tomorrow or later?
Choose a long-term alias to forward messages to your own inbox. You can pause forwarding from any sender individually.
Need to recover an important account?
Use an email address you control directly. You can’t recover a temporary inbox after it expires, and an alias depends on the destination inbox remaining active.
What sets them apart
| What to compare | Temporary email | Long-term forwarding alias |
|---|---|---|
| Getting started | Open the page and get an address | Sign in with your own email to receive a code |
| Where messages arrive | Web inbox | Forwarded to a verified email address |
| Address lifespan | 3 hours by default; extend it while it’s active | Kept until you pause or delete it |
| Separating senders | Switch addresses any time; the old one expires | Create a separate alias for each sender |
| Ongoing management | Old messages are no longer accessible after expiration | View the last 30 days of activity, then pause or delete the alias |
| Best for | One-time sign-up tests and short-lived verification codes | Subscriptions, ongoing projects, and follow-ups across days |
What is an email alias?
An alias is a public email address separate from your destination inbox. Messages sent to it are forwarded to your inbox, so you don’t have to share your personal email with every website. If you no longer need messages from a sender, you can pause that alias on its own.
An alias doesn’t make you anonymous, and it isn’t a separate inbox. Messages still arrive in your destination inbox, and forwarding can stop working if that inbox is disabled. Before testing an important account, make sure you know who will maintain the inbox that receives its messages.
Include address choice in your test plan
When testing sign-up flows, use the test checklist to check for resend, activation, and next-day follow-up steps. Then use the lifespan planner to estimate how long you’ll need to wait. That way, your temporary address won’t expire before the flow is complete.
For a simple delivery check, temporary email is usually the quickest option. To monitor notifications over time, create a separate alias for each sender so messages are easier to track. You can use both, but always keep recovery addresses for important accounts under your long-term control.
