send_simple_with_attachment.py

"""
Send an email with an attachment through Postmark's Django backend.

Attachment content is base64-encoded automatically — pass the raw
bytes/str you'd normally give EmailMessage.attach(), same as any other
Django email backend.

Run:
    poetry run python examples/django/send_simple_with_attachment.py
    python examples/django/send_simple_with_attachment.py  # with venv active
