Before you export

  • Search covers the right keywords and locations
  • Categories checked — wrong niches removed
  • Quick filters applied for your offer (e.g. No website, Under 4 stars)
  • Only leads you can actually help remain

Duplicates and overlaps

  • Duplicate businesses removed (Prospect Cheap merges them automatically)
  • Same email on several rows checked (chains, franchises)
  • Existing customers and open deals removed
  • Previously contacted leads removed or tagged

Emails

  • Rows without email moved to a call or social list
  • Email status checked; problem addresses removed
  • Personal emails preferred over role emails where both exist
  • Large or older lists verified before sending

Names and personalisation

  • Owner names present where you personalise
  • Low-confidence owner names reviewed or given a fallback greeting
  • Names and cities capitalised consistently
  • Custom first lines added for top prospects

Segments and export

  • List split into segments (niche, city, signal)
  • Each segment exported separately
  • Export format matches your tool (CSV, Instantly, GoHighLevel)
  • Each import tagged with source and date

Compliance

  • Opt-out line in every email
  • Suppression list checked
  • Sender name and business address included
