aid: neverbounce
name: NeverBounce
description: >-
  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.
