- Bounces on deliverable results are refunded automatically. Hunter offers no bounce guarantee.
- Credits never expire and plan credits roll over. Hunter's monthly credits reset and are shared with email finding.
- A bulk API with signed webhooks, official Node.js and Python SDKs, RocketShield and deliverability monitors.
