Resend is a transactional email platform; this toolkit lets agents send, schedule, retrieve, and manage emails via the Resend API.
Capabilities
- Send & schedule emails — send immediately or queue for future delivery using a
scheduled_attimestamp; returns a Resend-assignedemail_id - Manage scheduled emails — cancel or reschedule not-yet-sent emails by updating their delivery time or removing them from the queue
- Email status retrieval — fetch a single email by its Resend ID, including current delivery status
Secrets
RESEND_API_KEY — A Resend API key used to authenticate all requests. Obtain it from the Resend API Keys dashboard (requires a Resend account). Create a new key with at least Full Access (or a scoped key with send/read permissions matching your usage). Copy the key immediately after creation — Resend does not display it again.
Store this secret in Arcade via the Arcade secrets docs or directly at https://api.arcade.dev/dashboard/auth/secrets.
