Overview
Outreach is only as good as the list behind it
Bought databases go stale quickly, and scraped lists are full of wrong titles, old companies and bouncing emails. Every bad record costs your team time, hurts deliverability and makes campaigns look weaker than they are.
Our list building is done by people, not just tools. We research each account against your criteria, find the right contacts, verify what we find and keep one standard from the first row to the last.
- Current job titles at the right companies
- Business emails and phone numbers, checked before delivery
- No duplicates, including against the data you already have
