CaptainVerify is an email and mobile number verification service that cleans mailing lists and SMS databases to improve deliverability and reduce bounces, invalid addresses, and spamtraps.
What is CaptainVerify?
CaptainVerify is a SaaS tool that validates email addresses and mobile phone numbers. It accepts email lists (CSV, other formats) or single addresses via its web interface or API, and returns a classification (valid, invalid, unknown, free, risky, disposable). For mobile numbers, it performs HLR lookups to check operator status including portability. The service is developed by Captain Verify and operates from ISO 27001/SOC 2‑certified servers located in France.
