01 — Overview
What is
BounceBan
BounceBan is an email verification service that checks whether addresses are deliverable without sending an email. Its focus is catch-all, greylisted and gateway-protected addresses (Mimecast, Proofpoint, Barracuda, Office 365, Google Workspace), which many verifiers simply label as risky. Outbound and email marketing teams use it to clean lists before campaigns and keep bounce rates low.
02 — Who it’s for
Ideal Customer Profile
Used by outbound sales teams, lead generation agencies, email marketers and data providers. It fits startups through mid-sized teams that send cold or marketing email at volume.

Frequently Asked Questions
What is BounceBan used for?
BounceBan verifies email addresses before you send, so outbound and marketing teams can remove invalid contacts and keep bounce rates down.
How is BounceBan different with catch-all emails?
Instead of marking every catch-all address as risky, it uses its own methods to judge whether each one is actually deliverable, including addresses behind secure email gateways.
Which tools does BounceBan integrate with?
It connects with Clay, n8n, Google Sheets, ChatGPT GPTs and Claude Code, can verify CRM emails on a schedule, and works with any tool that can make an HTTP request.
Does BounceBan have an API?
Yes. BounceBan offers a documented verification API, plus skills for AI agents, so you can build email checks into your own apps and workflows.
