Bottom line
BounceBan is an email verifier built to resolve catch-all and secure gateway protected addresses that other tools return as unknown. It suits recruiters and agencies pulling enterprise contacts, where catch-all domains are common, who want those leads back without risking bounces. Single checks are free and paid credits start at $34 a month for 10,000 on subscription or $40 pay as you go.
Stands out for: Most verifiers mark every catch-all address as risky, while BounceBan returns a deliverable or undeliverable verdict for most of them without sending a test email. It also gives unlimited free single verifications, so a recruiter can check a hiring manager's address before a one off email at no cost.
Watch out for: Prices for packages above 10,000 credits only appear after you pick them on the pricing page, and the CRM Sync feature is billed as a separate subscription. Results on catch-alls are algorithmic judgements backed by a delivery rate guarantee, not a confirmed mailbox, so expect a small share to still bounce.
Overview
BounceBan is an email verification service focused on the addresses most verifiers give up on: catch-all domains, greylisted servers and mailboxes behind secure email gateways. It says it can reliably verify 85 to 95% of these, including Office 365, Google Workspace and Mimecast, Proofpoint and Barracuda protected domains.
Verification runs without sending emails, using proprietary signals, and most checks finish in seconds. You can verify single addresses free and without limit, upload bulk lists, call the API or use Sync to clean CRM records such as HubSpot every day.
Credits cost 1 per successful verification and roll over without expiring. The 10,000 credit package is $40 pay as you go or $34 a month on subscription, and packages scale to 1 million credits with custom pricing beyond that.
For recruiting agencies that source contacts at enterprise employers, catch-all domains can hide a large share of a list. BounceBan is designed to recover those contacts, and it plugs into Clay, n8n and Google Sheets, with a Claude Code plugin and a ChatGPT GPT for quick checks.
