Every Resend action

Each action is set independently to always allow, ask every time, or disabled. The mode below is the default before anyone changes anything.

Action	What it does	Type	Default
Get emailresend.get_email	Retrieve a single email sent through Resend by its id.	read	Always allow
List audiencesresend.list_audiences	List all audiences in your Resend account.	read	Always allow
List domainsresend.list_domains	List verified sending domains on the connected Resend account. Use this to discover which 'from' addresses are available for resend.send_email.	read	Always allow
Create contactresend.create_contact	Create a contact inside a Resend audience.	write	Ask every time
Schedule emailresend.schedule_email	Schedule a transactional email via Resend to be delivered at a future time (scheduled_at, ISO 8601).	write	Ask every time
Send emailresend.send_email	Send a transactional email via Resend. Requires a verified sending domain. Provide at least one of html or text.	write	Ask every time

Every write stops for a human

Write actions are off entirely until an admin turns them on, and even then each one halts the run and asks before it happens. There is no auto-approve mode anywhere in the product, on any plan. Disabling an action goes further: it is never offered to the model, so it cannot be asked for.
