Email

This notebook shows how to load email (.eml) or Microsoft Outlook (.msg) files.

Using Unstructured

#!pip install unstructured

from langchain.document_loaders import UnstructuredEmailLoader

loader = UnstructuredEmailLoader("example_data/fake-email.eml")

data = loader.load()

data

[Document(page_content='This is a test email to use for unit tests.\n\nImportant points:\n\nRoses are red\n\nViolets are blue', metadata={'source': 'example_data/fake-email.eml'})]

Retain Elements

Under the hood, Unstructured creates different "elements" for different chunks of text. By default we combine those together, but you can easily keep that separation by specifying mode="elements".

loader = UnstructuredEmailLoader("example_data/fake-email.eml", mode="elements")

data = loader.load()

data[0]

Document(page_content='This is a test email to use for unit tests.', lookup_str='', metadata={'source': 'example_data/fake-email.eml'}, lookup_index=0)

Using OutlookMessageLoader

#!pip install extract_msg

from langchain.document_loaders import OutlookMessageLoader

loader = OutlookMessageLoader("example_data/fake-email.msg")

data = loader.load()

data[0]

Document(page_content='This is a test email to experiment with the MS Outlook MSG Extractor\r\n\r\n\r\n-- \r\n\r\n\r\nKind regards\r\n\r\n\r\n\r\n\r\nBrian Zhou\r\n\r\n', metadata={'subject': 'Test for TIF files', 'sender': 'Brian Zhou <brizhou@gmail.com>', 'date': 'Mon, 18 Nov 2013 16:26:24 +0800'})
