In the Send to picker open the Deliveries or Pickup category. You will find ready-made entries for yesterday, today, tomorrow and the next six days, each showing its calendar date (e.g. Delivery tomorrow (09/07/2026)), plus Delivery on X Day (Select day on next field) / Pickup on X Day (Select day on next field) for any other date – when you pick one of those, fill the Trigger Date field that appears. The audience is every customer with an order for that delivery method on that date. Because dates are resolved when you save, create these campaigns on the day you want the date reference to be correct, or use the on X Day option with an explicit date.
