Hello.How to use it
- Paste a raw email or choose an EML file.
- Inspect the decoded message and headers.
Limits & privacy
Paste up to 64 KiB or inspect an EML file up to 1 MiB in your browser. Hosted pasted text uses plan input limits; EML files remain capped at 1 MiB. Up to 100 MIME parts, 16 nesting levels and 64 KiB of headers. Nothing is delivered, executed, fetched remotely or retained. Header claims and attachment MIME labels are untrusted; this is not signature verification or malware scanning.
Use this tool from the API reference or connect through the SDK, CLI, SSH, or MCP. Hosted calls share your plan allowances.
