Mailcheck

The product is an online email verification service that checks mailing lists for real, deliverable addresses and removes bots, inactive, disposable and catch-all entries to reduce bounces. It sells to marketers and B2B teams managing outbound and cold email campaigns, including small to large businesses and online stores. It differentiates from MX-only cleaning tools by validating addresses against social networks and other public sources and assigning a trust score, delivered as a SaaS with bulk upload, real-time checks and API access.
