Schedule a draft campaign to send at a set time.

write Confirm
Does what scheduling on the Review & Send page does. send_at is an ISO 8601 date and time with an offset, up to 60 days ahead, and the response returns the time Mailjet stored. Mailjet does not let you edit a scheduled campaign: use unschedule_campaign first. It reaches your contacts. By default you confirm each call; you can switch that off for this tool.
Parameters
| Name | Type | Description |
|---|---|---|
| campaign_id integer required | integer | Campaign ID from list_campaigns. |
| send_at string required | string | ISO 8601 date and time with offset, for example 2026-10-23T08:00:00+01:00. |
