Transparent Email is a small Python library that canonicalizes email aliases to help detect duplicate accounts. A caller supplies an address to the public function, which validates and parses it, selects the first matching mailbox provider, and returns that provider’s normalized address; unsupported domains retain the parsed address. Provider rules cover Gmail, Outlook, Yahoo, and 33mail. The provider implementations use a shared editable-email helper. Yahoo’s result follows the documented limitation that its base-name address may not exist. The graph follows the sampled runtime source; no external service or persistent storage is involved.
