We generally can't accommodate requests to prioritize last-minute content in the queue. We recommend uploading at least 3-6 months in advance of a known holiday or event, as many clients start planning their campaigns at least this early.
However, we understand this isn't always possible and that inspiration can strike at any time. If you have a time-sensitive shoot in the queue, you can let us know via Support, and we'll see what we can do--no promises. The good news is that our queue moves quickly, with most content being published within 2 days of submission.
