You can't send cold email without a list. And the quality of your list determines whether your campaign gets replies or crickets.
Here are the best B2B prospect database tools in 2026, what they actually cost, and how to choose.
What Is a Prospect Database?
A prospect database is a tool that lets you search for business contacts by company, job title, industry, location, and other filters — then export their email addresses for outreach. Think of it as a phone book for B2B sales.

How to Choose
For most startups and small teams, Apollo's free tier + LinkedIn Sales Navigator is the best starting combo. Apollo gives you emails, LinkedIn gives you context for personalization.
For lean budgets, manual research (LinkedIn + company websites + email pattern guessing) still works — it just takes more time.
Using a Database With ClickReach
ClickReach is a sending and CRM platform, not a database. You bring the list, we handle the outreach. Export contacts from Apollo, ZoomInfo, or LinkedIn as CSV, import into ClickReach with column mapping, add custom fields for personalization, and launch your sequence. The tools complement each other: database for finding, ClickReach for reaching.
