Resend
Arcade.dev LLM tools for sending and managing transactional email via Resend
1.0.4Resend is a transactional email platform; this toolkit lets Arcade-powered agents send, schedule, retrieve, and manage emails through the Resend API.
Capabilities
- Send & schedule email: Send transactional email immediately or queue it for future delivery by supplying a
scheduled_attimestamp; returns a Resend-assignedemail_id. - Retrieve email status: Fetch a single email by its Resend ID, including current delivery status.
- Manage scheduled email: Cancel or reschedule queued (not-yet-sent) emails by updating the scheduled timestamp or cancelling before delivery.
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. On that page, click Create API Key, choose a name, and select the appropriate permission level ("Full access" is required for sending, retrieving, and managing emails). Copy the key immediately — Resend does not display it again after creation.
