The start of campaign delivery You have now created a campaign. As illustrated in the simplified diagram of the campaign's structure, we have inserted the newly created bookings and attached creative: At this moment, the campaign is ready to start as you have: created a new campaign ( Add a campaign ), added bookings to the campaign ( Add a booking ), uploaded creatives ( Upload a creative ), and attached creatives to bookings or assigned positions to creatives ( Trafficking bookings and creatives ). The delivery will start at the earliest start date of one of the bookings associated with the campaign. Before a campaign starts, we recommend checking for possible issues that may inhibit or delay the start of the campaign. Adhese has built-in tools to make this job easy and effective: Statuses . By proactively monitoring the status of each campaign, you can ensure a smooth delivery without any unexpected delays.
