Resend
Arcade.dev LLM tools for sending and managing transactional email via Resend
1.0.1Resend is a transactional email platform; this toolkit lets LLM agents send, schedule, retrieve, and manage emails through the Resend API.
Capabilities
- Send & schedule email — send immediately or queue for later delivery by providing a
scheduled_attimestamp; returns a Resend-assignedemail_id - Manage scheduled email — cancel or reschedule not-yet-sent emails by updating their delivery time or aborting them entirely
- Email introspection — retrieve 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 one from the Resend dashboard under API Keys; click Create API Key, choose a name, and select the appropriate permission level (Sending access is sufficient for all toolkit operations). The key is displayed once at creation time — copy it immediately. A Resend account and at least one verified domain or email address are required before the key can send mail successfully.
See Arcade secrets configuration for how to store this secret, or add it directly at https://api.arcade.dev/dashboard/auth/secrets.
