Decision gist · record as of 2026-08-14
Yes. The SDK is actively maintained, has low install friction, carries a permissive MIT license, and provides a straightforward wrapper around a widely-used email validation service. Install it if you need to integrate ZeroBounce validation into a Python application. No known security vulnerabilities as of 2026-08-14.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a valid ZeroBounce API key to make requests; API calls will fail without authentication.
- Low install friction with a single runtime dependency (requests).
- Active maintenance with a recent release on 2026-08-14.

What it is and what it does
The ZeroBounce Python SDK is a client library that wraps the ZeroBounce email validation API, allowing developers to programmatically validate email addresses, check account credits, analyze API usage, and discover email formats. It depends only on requests and supports Python 3.7 and later.
The SDK provides both single-email and batch validation (up to 100 emails per request), file-based bulk validation with callback URLs, and utility methods for querying subscriber engagement and discovering email formats by domain or company name. It includes region-specific API endpoints (USA, EU, default) and custom URL support for alternative deployments.
Use it for
- Validate email addresses in real-time during user registration or form submission.
- Perform bulk validation of existing email lists to remove invalid or inactive addresses.
- Discover the likely email format for a person given their name and company or domain.
- Monitor account credit balance and API usage to track validation costs and quota.
- Analyze subscriber engagement history to identify inactive or problematic email addresses.
