  • Job title, which helps identify decision-makers
  • Company name
  • Email address
  • Phone number
  • Industry, for sector-specific targeting
  • Location, for geographic segmentation
  • Company size, for tailoring outreach

Best practices

  • Focus on quality over quantity. A smaller, well-targeted list beats a large, unqualified one.

  • Follow up consistently. Most conversions come after several touchpoints.
  • Track performance: open and response rates, conversion rates, average deal size, and sales cycle length.

Contact details go stale through job changes and restructuring. Update and verify lists regularly.

Duplicate entries

  • Improve customer relationships through personal communication
  • Shorten the sales cycle
  • Boost overall revenue and business growth
