Hunter.io
Find and verify professional email patterns — outbound research with deliverability guardrails.
Why it earns a place
Why I use it
Respect rate limits and local prospecting laws; use verification before you send.
Use cases
Best for
- Finding and validating a narrow B2B prospect set with Hunter.io
- Enriching contacts only after the account fits the target
- Keeping research quality higher than outreach volume
Start small
Quick start
- 01Define the account criteria
Write the industry, geography, company size, role, and disqualifiers before opening the database.
- 02Build a small list
Use Hunter.io to collect 20–50 accounts/contacts and manually inspect the first ten for obvious false positives.
- 03Enrich then personalise
Add only the fields needed for the outreach angle. Verify contact data and write a message around a real company-specific observation.
