"""
Email subscription example that registers an email address to receive
notifications when events are published to a channel.

Initializes the API client with application credentials and subscribes
the provided email address to the "notifications" channel. When events
are triggered on this channel, an email will be sent via SMTP.

Run from the examples/smtp directory with:
    python subscribe.py user@example.com

Before running:
    1. Update app_id, app_key, app_secret with your Pushi credentials
    2. Update base_url to point to your Pushi server
    3. Ensure SMTP is configured on the Pushi server

Requires: `pip install pushi`
