langchain_community.document_loaders.email.UnstructuredEmailLoader¶

class langchain_community.document_loaders.email.UnstructuredEmailLoader(file_path: str, mode: str = 'single', **unstructured_kwargs: Any)[source]¶

Load email files using Unstructured.

Works with both .eml and .msg files. You can process attachments in addition to the e-mail message itself by passing process_attachments=True into the constructor for the loader. By default, attachments will be processed with the unstructured partition function. If you already know the document types of the attachments, you can specify another partitioning function with the attachment partitioner kwarg.

from langchain_community.document_loaders import UnstructuredEmailLoader

loader = UnstructuredEmailLoader(“example_data/fake-email.eml”, mode=”elements”) loader.load()
