Temporary email / email alias
Choose temporary email for a one-off message, or a forwarding alias if you want to keep receiving emails. The difference isn't just how long the address lasts—it’s where your mail ends up.
One-time inbox
Free temporary email requires no login, and messages stay in your browser inbox. New addresses last 3 hours by default, with one 3-hour extension available—ideal for short-lived tasks you won't need to revisit.
Open a temporary inboxLong-term email forwarding
Log in with your real email address to create an alias, and incoming messages will be forwarded to it. An alias is a manageable forwarding address, not a separate mailbox or an independent account for sending email.
Create a forwarding aliasStart with the task
Think about what you’ll need later, not just right now. If more than one option fits, prioritize whether you’ll need the address again.
If you may need to reset a password, handle a refund, or prove account ownership, don't use an address that will expire for account recovery.
A forwarding alias can work for everyday community accounts. For banking, identity documents, and essential accounts, use a real email address you control long term.
Subscription updates, bills, and order status messages may arrive over time. What matters isn't whether you can receive mail today, but whether it will still have a reliable destination later.
Use a separate alias for each service and keep your real email as the destination. When you no longer want messages from one source, pause just that alias.
If you're only checking whether a welcome email, verification code, or form notification arrives—and can discard the test data—you probably don't need to keep the address.
Copy a new address, send a test email, and check it in the web inbox. Save anything you need before it expires; use a stable address for ongoing regression tests.
At a glance
The clearest way to compare temporary email and aliases is to look at login, where you read messages, and how long they’re kept.
| Feature | Temporary emailShort-term inbox | Forwarding aliasForwarding address for your real inbox |
|---|---|---|
| Login required | No account login needed; your browser stores the access credentials for the temporary inbox. | Log in with the real email address where you want to receive forwarded messages, using a verification code. |
| Where you read messages | Read messages in the Fwdsky web inbox. They won't automatically go to your usual email address. | Usually in your real inbox; you can also view forwarded-message records in the dashboard during the retention period. |
| Address lifespan | New addresses last 3 hours by default, with one 3-hour extension available. Check the countdown in the inbox for the exact time remaining. | Designed for ongoing mail, not subject to the temporary inbox's 3-hour countdown. Keep the alias, leave it enabled, and follow the service rules. |
| Can you pause and resume it? | There’s no switch to pause and resume forwarding. Changing the address invalidates the old one; it doesn’t temporarily disable it. | You can pause or re-enable it. Messages sent while paused are discarded, not held for delivery when you turn it back on. |
| Message retention | Temporary inbox messages aren't included in the 30-day archive of forwarded mail. Save anything you need before the address expires. | The dashboard stores forwarding records for 30 days. Copies in your real inbox depend on your email provider and your own actions. |
| Best for | One-time verification codes, short-term form testing, and downloads that won't require follow-up. | Ongoing subscriptions, community updates, shopping notifications, and messages you want to manage by sender. |
Three hours is the default lifespan of a temporary address; 30 days is how long forwarding records are archived. They’re separate timers.Plan how long you’ll need to receive email.
When to use each
Both types of address work in an email field. The deciding factor is whether you'll need to keep receiving messages after the task is done.
Temporary email · One-time sign-up codes
When trying a service you don't plan to keep, use a temporary address for verification. First check that the service accepts disposable email, then get your code. Temporary addresses aren't accepted by every website.
Not suitable for: Accounts you may need to recover, use to buy paid content, or rely on to store important information.
Go to the temporary inboxTemporary email · Development testing
Test registration forms, verification codes, and welcome emails with a new address. Check the subject, content, and delivery. Use fictional data, and choose a stable address if you need to test next-day notifications.
Not suitable for: Long-term regression tests that depend on a fixed address, or production workflows containing real customer data.
Estimate how long the task will takeForwarding alias · Ongoing subscriptions
Create a separate alias for each subscription, and have all messages delivered to your familiar real inbox. To stop messages from one source, unsubscribe with the service first; pause its alias only if needed, so other subscriptions aren't affected.
Not suitable for: Expecting an alias to filter out all spam automatically, or assuming messages sent while it's paused can be received later.
Create an alias for a subscriptionForwarding alias · Shopping notifications
Order confirmations, shipping updates, and refund notices may arrive in several messages. An enabled alias lets you share your real email with fewer merchants while keeping messages in your usual inbox.
Not suitable for: Deleting an alias while a refund or dispute is still in progress. Don't rely on the dashboard archive alone for important records, either.

A temporary inbox is the final stop. A forwarding alias is a waystation that sends messages on to your real email address.
Explore the email glossaryDelivered here, ready to read. Share the address with the sender, and messages arrive in the temporary inbox while it's valid. They won't be forwarded to your usual email address.
Received, then forwarded. The sender emails your alias, and Fwdsky forwards eligible messages to the email address you use to log in. The dashboard keeps forwarding records for a limited time.
Risks and misconceptions
Choosing a disposable inbox or email forwarding is a choice about how to receive messages—not a guarantee of complete anonymity or permanent backup.
An alias can reduce how often you reveal your real email address when signing up, but it doesn't encrypt message contents. The message, attachments, login details, or replies sent directly from your real inbox may still reveal your identity. Don't treat forwarding as anonymous communication.
Deleting an alias won't remove messages already forwarded to your real inbox or close your account with a merchant. Change your contact address on the relevant sites first, finish any returns or cancellations, then decide whether to pause or delete the alias. Delete inbox copies separately if needed.
If an address expires or changes, or you lose its access credentials, you may no longer be able to read messages. Don't use a temporary address for banking, identity documents, or essential work accounts. For everyday accounts using an alias, keep it enabled and make sure you can access your real inbox.
Next steps
If the task ends here, use temporary email. If you’ll need to stay in touch, give it a forwarding alias.
