NeverBounce is an email verification and list cleaning service (now part of ZeroBounce) that validates individual email addresses in real time and cleans bulk lists by checking syntax, mailbox existence, role addresses, disposable addresses, catch-all domains, and deliverability to reduce bounce rates for marketing, sales, and transactional senders. The NeverBounce v4 REST API at https://api.neverbounce.com/v4/ provides endpoints for single email checks, list jobs (create, parse, start, status, results, download), account info, and webhooks, with JSON responses over HTTPS. Authentication uses a per-integration API key (format secret_xxxx...) passed as the key parameter or in the Authorization header.
