Your temporary email address
Creating your inbox…
Waiting for the first message
Nothing has arrived yet. Send anything to the address above — a signup form, a test mail from your own inbox — and it appears here within seconds.
Listening for new mail…The mail service did not answer
Check your connection, or a content blocker may be blocking the request.
No message matches that
Clear the search box, or switch the unread filter off, to see the whole inbox again.
No message selected
Pick a message on the left to read it here. HTML mail renders in a sandboxed frame, and the raw headers are one click away.

How to create temp mail in one click
There is no form to fill in and no confirmation mail to click. The address exists before you have finished reading this sentence.
01
Copy the address
An inbox is created the moment the page opens. Hit Copy address — or show the QR code and scan it with a phone.
02
Paste it anywhere
Use it in a signup form, a download gate, a trial or a test. Anything sent to that address lands in the list on this page.
03
Read it and walk away
Open the message, follow the verification link or grab the attachment, then forget the address. Start a fresh one whenever you like.
What you get, for nothing
A throwaway inbox that behaves like a real one while it lasts.
An address in a second
No account, no password, no CAPTCHA. A random address is generated for you and remembered in this browser, so a reload brings it back.
Live, automatic refresh
The inbox checks itself every few seconds and pauses while the tab is in the background, so a waiting verification mail appears without you touching anything.
Search and unread filter
Sorted newest first with a search box and an unread-only switch, which is the difference between a usable inbox and a wall of mail on a busy address.
Real messages, not a summary
HTML bodies render in a sandboxed frame, plain-text mail stays readable, and the raw headers are there when you need to see where something really came from.
Attachments and downloads
Attachments download straight from the reader, and any message can be saved as a .eml file or copied out as JSON.
Keeps your real inbox clean
Signups that would otherwise mean years of newsletters go to an address that stops existing instead. Your own inbox never learns about them.
What people use a temp mail address for
One-off downloads
Gates that want an email in exchange for a file get a disposable one instead of yours.
Trials and demos
Try a product once without joining a mailing list you will never read.
Testing your own signup
Walk through a verification flow end to end without burning a real address on it.
Keeping spam out
Hand a throwaway address to anything you do not trust, and let it disappear afterwards.
Not for anything you care about. A disposable address cannot be depended on for password resets, purchases, or accounts you want to keep — once it is gone, it is gone. Treat every inbox here as public: anyone who knows the address can read it.
Free temp mail questions
Is CompMails really free?
Yes — 100% free with no sign up, no trial and no paid tier. The inbox is created the moment the page loads, and the ads on the page are what pay for it.
Does a temporary address need a password?
No. A random inbox is created for you and remembered in your own browser, so there is nothing to register. If you want the same address back later, use Custom address and choose a password you will remember.
How long does a temp mail address last?
Inboxes are disposable and meant for short use: expect one to stay alive for a few days. The mail provider removes the messages afterwards, so treat everything here as temporary and never use it for an account you care about.
Can I receive verification links and attachments?
Yes. Verification links open straight from the message, HTML is rendered in a sandboxed frame, and attachments download from the toolbar in the reader.
Is a temp inbox private?
Treat it as public: anyone who knows the address can read it. Nothing is stored on our servers — the address and its session live in your browser and the mail is read through the mail provider's API — but it is still the wrong place for anything sensitive.
Can I pick my own temp mail address?
Yes. Custom address lets you choose the name, one of the provider's domains and a password, so you can log back into the same inbox later.
