Marketing automation selection is often misguided, leading to poor outcomes. Common mistakes include focusing only on current needs, relying primarily on internal discussions over expert guidance, and letting vendors dictate the process. Additionally, many marketers are unprepared for ongoing changes in data, channels, and skills. To future-proof selection, organizations should define clear requirements, thoroughly search vendors, and implement strong project management. The optimal vendor can help customers adapt to innovations through flexible technology, training, expertise in vertical markets, financial stability, and a supportive culture.
