Getting Started with Clay: Finding Contacts for Paid Media and Marketing

Hey everyone! I am very new to Clay - I am the Co-Founder of GoAudience - we use AI and consumer spending data to help SMBs target the right customers and cut customer acquisition costs by 50%. I am mainly exploring Clay to look for people in Paid Media, Growth Marketing, Ads Specialists to send outbound emails to. I have added all the info in Clay and got some really good results but having difficulties generating their emails. It's frozen at Matching APIs in all columns. I want to start over, can you guide me on the best way to start, shall I start with Create New > Table > Find People > add the filters > then what? this is the right steps to follow? Also any tips on which plan to start with? 🥰
