What CaptainVerify is
CaptainVerify is a paid web and API service for verifying company email addresses and mobile phone numbers. Email checks use SMTP, MX, DNS, and other signals to assess validity. Lists can be uploaded as CSV or TXT files, with up to 1 million lines per file. Supported checks include batch and real-time verification, bulk uploads, form checks, and detection of disposable, role-based, and catch-all addresses. API V2 integrates email verification into applications and permits two simultaneous connections with 50 checks per minute. Mobile verification uses HLR Lookup across 96 countries and more than 300 operators. New accounts receive 100 free email credits, although there is no free plan; a free trial is available. Pricing starts at $7. Mobile options include 1,000 on-demand lookups for $8, paid once, excluding tax, or 5,000 monthly credits for $36 a month, excluding tax. Data is hosted in France with no transfer outside the European Union.
