Flanker is a Python library by Mailgun for parsing email addresses and MIME messages. It provides robust address parsing (single addresses and lists, with display names) and MIME message parsing used in Mailgun's production systems.

Use cases

• parse email addresses with display names in python
• validate and parse email address lists
• parse mime email messages
• extract addr-spec from email headers
• handle unparsable portions of address lists

When to choose

• you need battle-tested email address parsing in Python
• you must parse MIME messages reliably
• you want a library proven at Mailgun production scale

When to avoid

• you need guaranteed Python 3 support - it was built for Python 2.7 and Python 3 support is best-effort
• you need active feature development
• you need email sending or validation APIs rather than parsing
