Django Transactional Email API & SMTP Backend

Native Django Compatibility

SendPorter integrates directly with Django’s built-in django.core.mail subsystem. You can use standard Django email methods without installing heavy third-party packages, or use our official Python SDK for advanced parcel tracking and metadata tags.
