const out = [];

for (const item of $input.all()) {
  const date = new Date(item.json.date).toISOString().slice(0, 10);
  const sender = item.json.from?.value?.[0]?.address || "unknown@unknown";
  const domain = sender.split("@")[1];

  for (const file of Object.values(item.binary || {})) {
    out.push({
      json: { fileName: `${date}-${domain}-${file.fileName}` },
      binary: { data: file },
    });
  }
}

return out;

Build it

Pick your tool — same automation, step by step.

Copy and paste straight into an n8n canvas (Ctrl+V), or download and use Import from File. Then connect your own credentials and replace every YOUR_… placeholder.
