Resend
Arcade.dev LLM tools for sending and managing transactional email via Resend
1.0.1Resend is a transactional email API; this toolkit lets LLM agents send, schedule, retrieve, and manage emails through Resend via Arcade.
Capabilities
- Sending & scheduling: Send transactional emails immediately or queue them for future delivery using a
scheduled_attimestamp; returns a Resend-assignedemail_id. - Email lifecycle management: Retrieve the current delivery status of any sent or scheduled email by ID; cancel or reschedule queued emails before they are delivered.
Secrets
RESEND_API_KEY — A Resend API key used to authenticate all requests. Obtain it from the Resend dashboard under API Keys → Create API Key. Grant it at minimum Full Access (or scoped Sending Access if you only need to send; canceling, rescheduling, and retrieving emails may require broader permissions). Copy the key immediately after creation — Resend does not show it again.
Add this secret to Arcade at https://api.arcade.dev/dashboard/auth/secrets. For general guidance on configuring secrets in Arcade, see https://docs.arcade.dev/en/guides/create-tools/tool-basics/create-tool-secrets.
