HeroBounce uses advanced AI and multi-layer validation to catch invalid emails before they hurt your deliverability. Stop bounces, reduce spam complaints, and maximize email campaign ROI.
100 free validations/month • No credit card required
Every plan includes the full feature set. You only pay for validations — not for features.
Remove hard-bounce addresses before they damage your sender reputation and get you blacklisted.
Automatically reject temp-mail, throwaway, and one-time addresses at signup or list upload.
Identifies domains that accept any address — so you never waste sends on inboxes that silently swallow email.
Instantly flags malformed addresses before any network call is made, saving credits and time.
Our retry queue automatically re-validates greylisted addresses — turning unknowns into confirmed results.
Duplicate emails in your list are detected and skipped automatically. You never pay to validate the same address twice.
Our continuously updated database filters known honeypot and spam-trap addresses before they poison your list.
No separate API plan needed. Every paid account gets full API access — integrate in minutes with clear docs.
Pay-as-you-go credits roll over for 12 months. Buy when it suits you, use when you need them.
Upload CSVs of any size, validate in the background, download a clean filtered list when done.
Find and verify professional email addresses by name and company. Built-in — no separate tool needed.
Pay per validation, not per feature. Monthly plans reset automatically. No hidden fees, no contracts.
Set your own safe-to-send score. Bulk CSV exports include a safe_to_send column — you decide the cutoff, we flag anything below it.
Download exactly what you need - valid only, invalid only, risky, or the full results. No re-merging required, your original columns come back intact.
