"Few of us get into marketing or sales because we love data. But once we're in those roles, it's clear that we can't do our jobs well unless we get down and dirty with what the data is telling us. Susan's book, <i>Optimizing Sales & Marketing Data</i>, makes you a more effective data user. She takes your hand and talks you through what you need to do, how to do it and why. She also guides you on getting buy-in to support your work, which, as we know, can sometimes be the hardest step. As someone who's used various data sources throughout my career, and in various ways, this book has helped me take a more consistent, measured approach. I'd recommend it to every serious sales and marketing professional, regardless of where they are in their career. Buy it!"

"As a data professional, I found Susan Walsh's new book, <i>Optimizing Sales and Marketing Data: Strategies for Accuracy and Efficiency</i>, to be a wellspring of invaluable information that really bridges the gap between technical know-how and everyday business needs. With an engaging, conversational style and many real-world examples, Susan makes the essentials of data cleaning and maintenance both approachable and actionable. Her signature COAT framework (Consistent, Organized, Accurate, Trustworthy) stands out for me as a simple, yet powerful tool for anyone seeking to build better data habits. More than just a guide, it's a toolkit for building processes and a culture of data excellence; absolutely essential reading for anyone ready to turn their data into a true business asset."

"Susan Walsh tackles one of businesses most persistent challenges with refreshing practicality. While organizations invest heavily in analytics tools and AI, they often overlook the foundation: clean, properly classified data. Susan's Excel-based techniques and conversational style make data cleansing accessible without requiring coding skills. The COAT framework offers a simple yet effective structure any team can implement. If you're tired of making decisions based on flawed data or spending hours correcting the same issues, this book provides the roadmap you need."
