This document summarizes scientific findings from analyzing 200 million sales interactions. The analysis found that nearly all of the top performing sales cadences included multiple touchpoints, with 80% including a phone call and email on the first day. The best cadences showed more sales efforts early in the process. Personalization also helped, with response rates doubling when personalizing communications for just 20% of customers. The document recommends focusing sales efforts early in interactions and extending them over time for better results.
