Resend is a transactional email platform; this toolkit lets agents send, schedule, reschedule, cancel, and inspect emails via the Resend API.

Capabilities

  • Sending & scheduling — send emails immediately or queue them for future delivery using a scheduled_at timestamp; returns a Resend-assigned email_id
  • Lifecycle management — cancel or reschedule queued (not-yet-sent) emails by ID
  • Status inspection — retrieve a single email record by its Resend ID, including current delivery status

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 the key at minimum Sending access; for cancel/reschedule/get operations, Full access is required. Free-tier accounts can generate keys immediately after verifying a sending domain.

Store the key in Arcade as a secret. See the Arcade secrets guide for setup instructions, or manage secrets directly at https://api.arcade.dev/dashboard/auth/secrets.
