Hiii, sorry late to the game. John T. re your Q about only running specific lines and not the entire sheet - you can try using Conditional Run Formulas. You can apply them to any enrichment so that Clay only runs on rows that meet your condition (in this case: “new” contacts). You might have to tweak the logic a bit to match your workflow, but once set up, it saves a ton of reruns. Note: this option keeps your logic in Clay. Here’s a how-to guide: https://www.clay.com/university/guide/conditional-runs#:~:text=How%20do%20I%20use%20conditional%20runs%3F&text=Navigate%20to%20the%20Run%20Settings,click%20on%20%E2%80%9CUse%20AI%E2%80%9D.&text=Define%20the%20logic%20that%20determines%20how%20the%20condition%20will%20evaluate.&text=Click%20%E2%80%9CGenerate%20formula%E2%80%9D%20to%20automatically,your%20condition%20into%20a%20formula
