Details
Verify the validity and deliverability of up to 1,000 email addresses in a single batch using the NeverBounce API. Requires your own NeverBounce API key for bulk operations. Each email undergoes syntax validation, DNS and MX record lookup, and SMTP-level mailbox verification without sending actual emails. Additional checks detect disposable providers, role-based addresses, spam traps, and duplicates. Returns per-email verification results along with aggregate statistics including counts for valid, invalid, catchall, unknown, disposable, and duplicate addresses. For large jobs that exceed the timeout, returns a job ID for checking status later.
Use Cases
Cleaning email marketing lists before campaigns, bulk CRM data hygiene and deduplication, validating imported contact lists, preparing email lists for migration between platforms, lead list verification before sales outreach, newsletter subscriber list maintenance, reducing bounce rates for high-volume senders, pre-send verification for transactional email systems, periodic database cleanup and validation audits.
