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. Candidate codes are heuristic matches, not verified credentials. Links are displayed as text and are never fetched. This does not test delivery or complete a signup flow.
Use this tool from the API reference or connect through the SDK, CLI, SSH, or MCP. Hosted calls share your plan allowances.
