Introduction

Build with the BounceCheck API

BounceCheck is a REST API. JSON over HTTPS, no SDK required. Verify a single email in real time with an API key, or process thousands of addresses through bulk uploads in your dashboard.

The base URL for every request is:

https://api.bouncecheck.email/api/v1

What you can do

• Single verification — check one address and get a deliverability result in 1–3 seconds.
• Disposable check — detect throwaway/temporary email domains.
• Bulk verification — upload a CSV/XLSX in the dashboard and download cleaned results.
