Resend is a transactional email API; this toolkit lets LLMs send, schedule, retrieve, and manage emails through Resend's API via Arcade.
Capabilities
- Sending & scheduling — Send transactional email immediately or queue it for future delivery using a
scheduled_attimestamp; returns a Resend-assignedemail_id. - Email lifecycle management — Retrieve email status by ID, reschedule a pending email's send time, or cancel a scheduled email before it is sent.
Secrets
RESEND_API_KEY — A Resend API key used to authenticate all requests. Obtain one from the Resend dashboard under API Keys. Create a key with at least Full Access (or scoped to sending and email management) on the domain(s) you intend to use. Free-tier accounts can generate keys immediately; no paid plan is required to start. Paste the key value as the secret in Arcade.
See Arcade secret configuration docs for how to store secrets, or manage them directly at https://api.arcade.dev/dashboard/auth/secrets.
