Frequently Asked Questions

How does Hunter find email addresses?

Hunter uses public web sources and proprietary patterns to locate email addresses. For the Email Finder, you enter a first name, last name, and domain; Hunter then returns the most likely email and verifies it.

Can I verify emails before sending outreach?

Yes. Hunter has an Email Verifier that checks whether an email is deliverable. You can also verify addresses when importing a list or directly from your leads before launching a campaign.

How does the Campaigns feature work?

Campaigns lets you compose, schedule, and send personalized cold emails. Emails are sent automatically within your set “sending window” and daily limits.

Can I schedule a campaign to start in the future?

Yes. In your campaign’s settings, you can choose a “Start the campaign on a specific day.”

Can I A/B test my campaigns in Hunter?

Not directly. Hunter doesn’t have built-in A/B testing, but you can manually split your lead list into two campaigns, duplicate your campaign content, and compare performance.

Should I include an unsubscribe link in my campaign emails?

Yes. It’s strongly recommended, not just for deliverability but also for compliance (GDPR, CAN-SPAM). Hunter automatically detects unsubscribe replies (e.g., if someone replies with "unsubscribe") and blocks future emails to that contact.
