If you pull lead lists from multiple sources, it’s easy to lose track of what you’ve already marketed or skip traced. Over time, the same owners quietly reappear across new lists, causing you to pay for the same leads again and again. GoSiftly is designed to be used before skip tracing or launching a campaign. It scans your lists inside Google Sheets™ and removes duplicates so you only export truly new leads. Everything runs directly inside Google Sheets™, with no external platforms or data transfers required.
