OrbiSearch

OrbiSearch is an email validation tool specialized in resolving catch-all domains and other difficult B2B emails that competitors mark as "risky". Unlike traditional validators, it verifies mailbox existence instantly without sending actual emails to prospects, achieving industry-leading accuracy with pay-per-use pricing. The platform combines SMTP validation with proprietary mailbox detection technology to confirm deliverability in real-time, processing over 1,000 emails per minute. Features include bulk CSV processing, RESTful API access, webhook callbacks, syntax and domain checks, and MX record verification. Benchmarked at 96.3% bounce prevention on real campaign data — outperforming BounceBan, Icypeas, and Enrichley — with 500 free validations for new users, no credit card required. Built for sales, marketing, recruitment, and business development teams running cold outreach at scale.
