Dealing with High I No Longer Work Here Responses in Cold Outreach

Hi guys, I’m facing a repeated issue. The most common “no” response we get from our cold outbound is consistently “I no longer work at this company”. No matter whether I use Clay, Apollo, or Linkedin enrichment as my data source, this is without a doubt our most common error. I’m even using additional meta-data fields like “is current” in their most recent job to verify that it’s legit, still - this “I no longer work here” response makes up >50% of my negative responses. The only way I can think to solve for this problem would be to have clay to manually scrape their LinkedIn profile and confirm that this is the most up-to-date position. However, we will need to run this on every row, and it would be extremely expensive. Has anyone else faced this issue, and come up with a better workaround?
