We recently exported - 2,000 companies from Grata across several industries for one mandate. We’re running a 5-day email sequence alongside LinkedIn outreach, and after applying the mandate filters, we’re down to roughly 400 quality targets. The next step is hitting those same 400 through email + LinkedIn + physical letters + cold calls. The challenge now is contact data: Grata exports don’t always give us the direct owner/executive contact often it’s just an office number. We’re trying to figure out the best way to enrich those 400 targets before we start calling. For searchers doing proprietary sourcing, are you using Apollo, Linkt.ai, or something else to get direct owner emails and phone numbers? And when do you bring physical mail and cold calling into the process?
