Fits between the tools
you already use

BounceBrake picks up where your verifier stops and hands clean leads to the tool you send from. No new workflow, one extra step that pays for itself in leads you keep.

Leads out

Send to your outreach tool

Connect a sending platform once per workspace with its API key. When you upload a list, choose a campaign and map extra columns (first name, company and so on). When the file finishes, every valid address is added to that campaign.

Use it after your verifier

BounceBrake works with any verifier, because it works from a CSV. Export the catch-all, accept-all, risky or unknown segment and upload it. Soon you’ll be able to store your verifier’s API key in a workspace and have it run that first pass for you.

Build your own workflow with the API

Clay, Zapier, Make, n8n and your own code can all call the BounceBrake API with an HTTP request. Submit addresses with an identifier of your own (a row or record id), and we post the verdict to your HTTPS endpoint, signed so you can trust it.
