Frequently Asked Questions
Why would I switch from ZeroBounce to StopBouncing?
The main reasons customers switch are pricing simplicity and GDPR compliance. StopBouncing uses a straightforward pay-as-you-go credit model with no monthly minimums and EU-hosted infrastructure. If you prefer a simple per-email price without subscription complexity, StopBouncing may be a better fit.
Is StopBouncing as accurate as ZeroBounce?
Both services use SMTP-level verification and maintain databases of disposable email providers. Accuracy for valid and invalid addresses is comparable — over 98%. Catch-all domains are an honest unknown for both services, as the nature of catch-all configuration makes individual mailbox verification impossible.
Does StopBouncing offer the same API as ZeroBounce?
StopBouncing offers a REST API with similar functionality: single email verification, JSON responses, and bearer token authentication. The endpoints, parameter names, and response schemas differ, so migration requires updating your integration code. Our API documentation provides a complete reference.
What happens if I have unused credits from ZeroBounce?
Credits purchased at StopBouncing do not expire, so you can purchase credits and use them at your own pace. There is no pressure to use credits before an expiry date.
Is StopBouncing a good ZeroBounce alternative for small senders?
Yes — StopBouncing's pay-as-you-go model is well-suited for small or irregular senders. There is no monthly subscription, no minimum commitment beyond the first credit pack, and credits do not expire, so you only spend when you have emails to verify. For high-volume senders who verify millions of addresses monthly, compare the per-email price at your actual volume.
Is StopBouncing GDPR compliant?
Yes. StopBouncing is hosted entirely within the EU. Email addresses processed through the service are verified against mail servers and are not stored beyond the verification session. This makes StopBouncing easier to use under GDPR than US-hosted alternatives, which may require additional transfer safeguards.
Does StopBouncing support bulk email verification like ZeroBounce?
Yes. Upload a CSV file through the StopBouncing dashboard, and the system detects the email column automatically and verifies every address. Results are available for download with a status column added to each row. The same verification is available through the API for programmatic bulk processing.
