  • automations_send_testSends up to five selected saved Automation email steps to one explicit test address.No findings

    Why it is in this group

    • The name "automations_send_test" says "send": a word for sending, and what is sent cannot be taken back.
    • The server marks it destructive (destructiveHint: true).
    Description, as the server wrote it
    Sends up to five selected saved Automation email steps to one explicit test address. This does not start the Automation or run other actions. Effect: external-email. Retry with the same idempotency_key. Permissions: live_actions:write, subscribers:read, automations:write. API reference: https://mailrith.com/developers/api-reference.

    • The name "automations_update" says "update": a word for a change.
    • The description says "cannot be restored".
    • The server marks it destructive (destructiveHint: true).
    Description, as the server wrote it
    Updates an existing draft or paused Automation. Before changing a running Automation, read it by ID, retain its status in the current task only, pause it, apply the update, and use bounded direct item reads until is_updating is false. Run preflight, return it to running only if it was running before and preflight passes, and verify the final status. If the update fails before changing the Automation, restore its prior running status when preflight passes. If readiness or the prior status cannot be restored, leave it paused and immediately report the failure; never activate an Automation that was not already running. Effect: workspace-change. Retry after reading the current resource state. Permission: automations:write. API reference: https://mailrith.com/developers/api-reference.

    • The server marks it destructive (destructiveHint: true).
    Description, as the server wrote it
    Schedules a draft for future delivery, or changes the delivery time of an existing scheduled Broadcast. This uses Mailrith's durable scheduled-send path and does not start delivery immediately. Effect: external-email. Retry after reading the current resource state. Permissions: live_actions:write, broadcasts:write. API reference: https://mailrith.com/developers/api-reference.

    Why it is in this group

    • The name "broadcasts_send" says "broadcast": a word for sending, and what is sent cannot be taken back.
    • The server marks it destructive (destructiveHint: true).
    Description, as the server wrote it
    Immediately creates durable preparation for a broadcast draft or scheduled send. Mailrith calculates the exact Subscriber total and checks provider readiness in the background before delivery. A 202 response means the durable send was accepted, not that provider delivery is complete. Reuse the same idempotency key if the response is lost. Effect: external-email. Retry with the same idempotency_key. Permissions: live_actions:write, broadcasts:write. API reference: https://mailrith.com/developers/api-reference.

    • The description says "cannot be restored".
    • The server marks it destructive (destructiveHint: true).
    Description, as the server wrote it
    Updates an existing Broadcast draft. Scheduled, running, completed, and failed Broadcasts cannot be changed here. Before changing a scheduled Broadcast, read it by ID and retain its scheduled_at in the current task only. If the saved time is no longer safely in the future, ask the user for a new time before unscheduling. Otherwise unschedule it, apply the update, reschedule it for the same time, and verify both status and scheduled_at. If the update fails after unscheduling, restore the unchanged Broadcast to the same future time when possible. If the schedule cannot be restored, leave it as a Draft and immediately report that it will not send; never choose a replacement time without the user. Effect: workspace-change.
