Resend
for LuumenAI
Read audiences, contacts, and broadcasts. Send changes through approval.
Resend handles the mail your systems send: incident notices, maintenance windows, status updates. Connect it with an API key and Luumen can read audiences, contacts, templates, broadcasts, and webhooks on request. Changes — a new contact, a draft broadcast, a deleted API key — are previewed first and go out only after you approve them.

Questions
Authorize once with API token. Luumen lists the scopes each action needs before you approve the connection, and credentials never appear in the chat.
Read actions answer immediately. Anything that writes — add contact to segment, cancel email, create api key, create audience, and more — is shown as a plan and requires approval by default, including the 12 actions classified as destructive. Administrators configure that per tool, so you decide exactly which actions can ever run unattended.
You decide. Actions are granted per agent, skill, and team, and per environment — production is not staging. Read access can be broad while writes stay narrow.
Every call to Resend — read or write, approved or declined — is recorded with the actor, the input, and the result, and can be linked to the ticket or change record.
