Email Deliverability Test
Send one real message to the unique address below. We receive it through the same production Postfix path as our temporary inbox and turn its delivery evidence into a readable report.

Send your test message
Use your normal sending system. Keep this page open; the report appears automatically after the message arrives.
Waiting for your email
No message has arrived yet. Delivery can take a few seconds.
Privacy: the report, address, and raw header expire automatically after about one hour. Message bodies and attachment files are never stored by this tool.
Frequently asked questions
- Does this prove the email will reach every inbox?
- No. It shows what reached this server and highlights structural issues. Each receiving provider also applies its own reputation, content, and user-specific filtering.
- Is the message content stored?
- No. This tool stores only the received header and a structured report for about one hour. Bodies and attachment bytes are discarded.
- Why is there no spam score yet?
- The current server has not been confirmed to run Rspamd. The UI states that clearly instead of presenting an invented score; independent scoring can be added later.
