Contact Verification API
The Contact Verification API validates the deliverability and risk signals of an email address or phone number, helping teams identify invalid, incorrect, or high-risk contacts—improving reach rates while reducing communication cost and wasted system resources. Given an email or phone number, the API returns a status assessment (e.g., format validity, reachability, and potential anomaly/risk indicators), enabling data filtering and prioritization before outreach. It is primarily used for data quality control and operational efficiency optimization, and can be combined with enrichment/prospecting/campaign APIs to improve overall sales, marketing, and customer communication performance without additional manual effort.
