After an IO has been signed, a ____ should occur with a vendor prior to campaign launch.

A kick-off call is a crucial step after an insertion order (IO) has been signed and before launching a campaign. This meeting typically involves both the advertiser and the vendor to align on campaign goals, key performance indicators (KPIs), timelines, and strategies. The purpose of the kick-off call is to ensure that all parties have a clear understanding of the campaign details, expectations, and roles, thereby facilitating smoother execution and communication throughout the campaign.

This phase is also an opportunity to discuss any final adjustments needed, confirm responsibilities, and foster a collaborative relationship that can contribute to the campaign's overall success. It sets the stage for a structured and organized launch, minimizing the potential for misunderstandings or miscommunications.
