Delivery

Emails are sent from notifications@cn2.ai via Resend. If you're not receiving emails, check your spam folder and ensure the address is whitelisted.

Email notifications supplement — but do not replace — webhook events. For programmatic alerting, use webhooks which cover all the same events plus earning.batch_credited.
