FAQ
What is the best free lead generation tool?
Apollo.io, Hunter, and Snov.io all offer free tiers that let you find and verify a limited number of contacts each month. They are a good way to test prospecting workflows before committing to a paid plan or an enterprise database like ZoomInfo.
What is the difference between a prospecting database and a data enrichment tool?
Prospecting databases like Apollo.io and ZoomInfo let you search for new contacts that match your ideal customer profile. Enrichment tools like Clearbit and Clay add missing details — company size, role, technologies — to leads you already have. Many teams use both together.
How do I keep lead data accurate and deliverable?
Use an email verifier such as Hunter or Snov.io to confirm addresses before you send, since databases go stale as people change jobs. Re-enrich records periodically with a tool like Clearbit or Clay so firmographic and contact data stays current.
