ClearBounce

ClearBounce verifies email addresses before you send — catching invalid, disposable, and risky contacts so campaigns land in the inbox instead of bouncing. Bulk list cleaning, a real-time API, an email finder, and form protection in one toolkit, with credits that never expire. The affiliate program pays a 50% recurring commission for the customer's lifetime, with monthly payouts and a $50 minimum.
