Resend is a transactional email API; this toolkit lets agents send, schedule, retrieve, and cancel emails via Resend through Arcade.
Capabilities
- Send & schedule email: Send transactional email immediately or queue it for later delivery by providing a
scheduled_attimestamp; returns a Resend-assignedemail_id. - Manage scheduled email: Cancel a not-yet-sent email or reschedule it by updating its delivery timestamp before it goes out.
- Email retrieval & status: Fetch a single email by its Resend ID to inspect current delivery status and metadata.
Secrets
RESEND_API_KEY — A Resend API key used to authenticate all requests. Obtain it from the Resend API Keys dashboard after creating a Resend account. Generate a new key, assign it a name and the appropriate sending permissions (full access or sending-only), and copy the value immediately — it is not shown again. The key must belong to a domain that has been verified in your Resend account for email delivery to succeed.
Store this secret in Arcade via the Arcade secrets dashboard or follow the Arcade secrets configuration guide.
