We verify catch-all emails
BounceBan verifies all kinds of emails and shines at verifying emails that are catch-all or protected by SEGs (Secure Email Gateway). We don't simply mark all catch-alls as risky like others do - we help you identify those that are deliverable indeed while achieving excellent overall delivery rates, all without sending an email.
