Email testing, explained
Can I use this without signing up?
Yes. Use this browser tool or create an inbox through our HTTP API. Both share the same limits: three creations per network per UTC day, 24 hours per inbox, 100 incoming emails and 10 MB.
Are my messages public?
No. This browser uses a private cookie; API clients use an inbox bearer token. Anyone holding that secret can read the inbox. This is not end-to-end encryption.
What happens after 24 hours?
Access and receiving stop at expiry. A cleanup worker removes the mailbox contents; encrypted backups follow our backup retention policy. Save a browser inbox to an account before expiry if you need to keep it under your plan’s retention policy.
Can an AI agent receive a verification code?
Yes. Create an inbox, use its address in your test application, and call the wait endpoint to retrieve the email and extracted codes or links. No CLI or browser automation is needed.
