Ready when you are
Create a disposable email in three steps
An address is created automatically when you open the page. No name, phone number, or password required—just copy it and use it on the site you need.
Wait for your email
Keep this page open to see new messages in your inbox. Verification codes usually arrive within seconds, and you can refresh manually to check.
Read it, then move on
Delete emails you no longer need after verification. When the countdown ends, the address and its messages can no longer be accessed.
Use cases
Keep one-time email separate from your everyday identity
Temporary email addresses are suited to short-term, low-risk tasks that do not require ongoing contact. They help keep marketing emails out of your main inbox, but they are not a replacement for a recovery email on important accounts.
Receive signup codes
When testing a new service or confirming a non-critical account, use a separate address for the verification code instead of sharing your usual email.
Get a one-time download
When a white paper, template, or software trial requires an email, a temporary inbox keeps follow-up promotions separate.
Test email flows
Developers and marketers can quickly check subject lines, sender names, and basic formatting without repeatedly creating test accounts.
Try an unfamiliar website
If you are not sure you will keep using a service, try it with a temporary email first. Once you trust it, switch to a long-term address.
Expiration
A three-hour window for the task at hand
Tempcat temporary email addresses are available for three hours by default, with the countdown showing the time remaining. Changing your address destroys the old inbox and starts a new one, so do not use an old address as a long-term contact.
Messages may be delayed by sending queues, rate limits, or greylisting. If you still have time, wait a minute before refreshing. If the old address was rejected by the site, try again with a new one.
- Complete email verification before closing your browser
- Do not use the address for password recovery
- Do not receive banking, medical, or government documents
Remember the time limit
00:00:00 Once this appears, the old address can no longer be used to read past emails. To continue, create a new address and update your email on the service you are using.

How do disposable emails, anonymous emails, and forwarding aliases differ?
These terms are often used interchangeably. The real differences are how long the address lasts, whether it can receive mail continuously, and whether it is suitable for account recovery.
| Type | Duration | Best for | Not suitable for |
|---|---|---|---|
| Tempcat disposable email | 3 hours by default | Verification codes, trials, one-time downloads | Important accounts and long-term communication |
| Email forwarding alias | Managed by you over time | Subscriptions, shopping, and keeping your main email separate | Short-term tasks with no lasting association |
| Primary everyday email | Long term | Work, bills, account recovery | Bulk signups on unfamiliar websites |
Delivery help
What if my disposable email does not receive a message?
First, make sure the address you copied exactly matches the one submitted to the site, especially hyphens, numbers, and the domain. Some sites actively block known disposable email domains; refreshing repeatedly will not change that.
If the address is correct, check that the countdown is still running and allow the sender time to process the message. A verification email may be delayed by the sender or generated only after you click “Resend.”
1. Check the address
Return to the submission page and compare the address character by character. Make sure no extra spaces were copied.
2. Wait and refresh
Wait 30 to 60 seconds, then refresh once. Avoid triggering many verification codes in a row.
3. Change addresses or use an alias
If the sender rejects disposable domains, change your address. For ongoing communication, use a forwarding alias.
Privacy limits
Temporary does not mean completely anonymous
A no-signup email reduces how often you submit your personal address, but it cannot hide your browser, network address, or data collected by the site you visit. Anyone with access to the current inbox credentials may be able to view its contents.
Do not receive sensitive information
Bank notices, identity documents, medical records, contracts, and private photos should never go into a disposable inbox.
Do not rely on it for account recovery
There is no guarantee you can regain the address after it expires. An important account linked to it may be impossible to reset later.
Read the website’s privacy policy
A temporary address only controls the email entry point. How the website handles device, Cookie, and behavioral data is determined by its own policy.
FAQ
About no-signup disposable email
Can a no-signup email receive verification codes?
It can receive most standard email verification codes, but the sender may block disposable email domains. Verification codes are sensitive credentials, so do not forward them to anyone after reading them.
How long do temporary email addresses last?
This service provides a three-hour lifespan by default. Check the countdown on the main screen for the exact time remaining. Create a new inbox after expiration.
Can I send emails with it?
The current temporary inbox is receive-only and cannot send messages. This reduces abuse risk and avoids making users think it is a full email account.
Is a disposable email free?
Creating and receiving temporary emails requires no signup and no payment information. Long-term email forwarding is a separate feature managed after logging in.
Can I come back after closing the page?
It may be possible in the same browser session while the inbox is still active, but it should not be treated as reliable storage. Use a controlled long-term email address for anything important.
Keep receiving mail without exposing your main address
If a site will send order updates, renewal notices, or account alerts, create a manageable email forwarding alias instead of relying on a three-hour temporary address.
