Implementing or replacing a marketing automation solution requires convincing executives and overcoming challenges. These include gaining buy-in from sales and other departments, competing initiatives, skepticism about value, and lack of understanding. To increase approval probability, thoroughly understand decision-makers, present concepts simply, provide implementation costs and anticipated results, candidly discuss risks, define clear metrics, separate short and long-term goals, and use case studies and referrals to bolster the case. Passion and commitment can also help convince executives.
