Email Infrastructure

We abstract the provider layer. Current supported drivers:

Resend: Default. High deliverability.

AWS SES: Cheaper for high volume.

SMTP: Generic fallback.

To handle large lists (e.g., 10k subscribers):

Job Creation: The campaign creation puts a "Job" in the database.

Cron Worker: A background worker picks up the job.

Batching: Emails are sent in batches of 50 to avoid timeouts and rate limits.

Idempotency: We track sentTo list to prevent duplicate emails if the job restarts.
