Important Notes

Approximation Method: This endpoint uses intelligent sampling techniques to provide bounce rate estimates. While results are close to actual values, they are approximations and may vary from precise validation results.
Zero Cost Analysis: Perfect for getting insights into your email list quality without spending credits. Use this before deciding whether to proceed with full validation.
Not 100% Accurate: Results are estimates based on analysis patterns. For exact validation results, use the Clean Email List endpoint.
