Resend is a transactional email API; this toolkit lets agents send, schedule, inspect, and cancel emails through Resend via Arcade.
Capabilities
- Send & schedule emails — send immediately or queue for future delivery using a
scheduled_attimestamp; returns a Resend-assignedemail_id - Manage scheduled emails — reschedule or cancel queued emails before they are sent
- Email status inspection — retrieve a single email by ID to check current delivery status
Secrets
RESEND_API_KEY — A Resend API key used to authenticate all requests. Generate one from the Resend API Keys dashboard (requires a free or paid Resend account). Create the key with Full Access or, for least-privilege, with Sending access only; if you also need to retrieve or cancel emails, ensure the key has read permissions. Copy the key immediately after creation — Resend does not display it again.
Add this secret to Arcade at https://api.arcade.dev/dashboard/auth/secrets. See the Arcade secrets guide for configuration details.
