Resend is a transactional email API; this toolkit lets agents send, schedule, retrieve, and manage emails through Resend.
Capabilities
- Sending & scheduling — send emails immediately or queue them for future delivery via a
scheduled_attimestamp; returns the Resend-assignedemail_id. - Email lifecycle management — retrieve delivery status for any sent email by ID, reschedule queued emails, or cancel scheduled emails before they go out.
Secrets
RESEND_API_KEY — A Resend API key used to authenticate all requests. Generate one in the Resend dashboard under API Keys → Create API Key. The key requires at least Sending access for send/schedule/cancel/reschedule operations; Full access is needed if you also require read operations. Copy the key immediately after creation — Resend does not display it again.
