Temporary email

Free temporary email, no sign-up

Open the homepage and the inbox is already there — paste the address into any sign-up form and the verification code shows up highlighted, ready to copy. If the inbox matters, make it permanent and private for R$ 5 — no subscription.

Try it in 3 steps

1

Open the homepage

A free inbox is already created and waiting — a unique, never-repeated address.

2

Paste the address into the sign-up

Use it on any site or app that asks for email. The inbox refreshes itself every 5 seconds.

3

Copy the highlighted code

We detect the verification code inside the email and keep it ready to copy with 1 click.

What the free inbox includes

  • Unique address generated on the spot, no account
  • Verification code and links highlighted automatically
  • HTML and text rendered safely
  • Lives for 24 hours — or change the address whenever you want
  • Up to 10 messages, live

For R$ 5 it becomes permanent

  • Yours forever: private, only your account sees it
  • Exclusive domains that pass verification checks
  • Attachments and full inbox history
  • Developer API with code long-poll
  • Pay once, receive forever — no monthly fee

Quick questions

Do I need an account to use the temporary email?

No. The free inbox opens on the homepage with zero sign-up. An account is only needed for permanent inboxes (R$ 5) and wallet top-ups.

How long does the free inbox last?

24 hours — then it and its messages are gone. The “change address” button creates another instantly, also free. For an inbox that never expires, create the permanent one for R$ 5.

Can anyone else read my messages?

No. Unlike public-inbox services, your address is unique and messages only appear in your browser (an anonymous cookie identifies the inbox).

What if a site blocks disposable emails?

Free domains can be blocked by stricter services — that's the price of free. Permanent inboxes use our own domain pool, off the disposable lists.

Can I automate it via API?

Yes: with an API key you create inboxes and receive the ready verification code via long-poll — built for automated sign-up testing. See the API documentation.

Public API for developers

Automating sign-ups? The inbox hands you the verification code via API.
