NeverBounce

Validate single emails or run bulk-list verification jobs via NeverBounce. 6 tools, query-string API-key auth.

Setup

2 (developers.neverbounce.com).

Setup:

  1. Sign in to https://app.neverbounce.com → Apps → New API Key.
  2. Copy the key. Set NEVERBOUNCE_API_KEY.

Authentication: query-string ?key=.... NeverBounce also supports a custom Auth header but query-string is the primary.

Single vs Bulk:

  • neverbounce_single_check: synchronous single-email verification. ~1 credit. Returns result (valid/invalid/disposable/catchall/unknown) + flags + suggested_correction.
  • neverbounce_create_job: async bulk verification of a list (up to 1M emails). Returns job_id; poll status with neverbounce_job_status until status='complete'; then neverbounce_job_results to fetch.
