## Frequently Asked Questions

**What is the difference between [EmailVerifierPro.app](https://emailverifierpro.app) software and the [VerifyEmail.app](https://verifyemail.app) service?**  
EmailVerifierPro.app is self-hosted software that you can run on your own server, providing email validation features similar to ZeroBounce. VerifyEmail.app, on the other hand, is a cloud-based, pay-as-you-go email verification service that also offers features comparable to ZeroBounce. Both systems' APIs are supported and can be used with this plugin.

**Do I need an [EmailVerifierPro.app](https://emailverifierpro.app) software or [VerifyEmail.app](https://verifyemail.app) account?**  
No, but connecting your own instance enables advanced email validation. The plugin works with basic blacklist features out of the box.

**Can I block disposable or temporary emails?**  
Yes! Add known disposable domains to the domain blacklist, or use [EmailVerifierPro.app](https://emailverifierpro.app) / [VerifyEmail.app](https://verifyemail.app) for automatic detection.

**Will this block spam bots?**  
It helps reduce spam by blocking known bad emails/domains and duplicate IPs, but for best results use alongside a full security plugin.

**What happens if I enable 'Delete all plugin data on deactivation'?**  
All plugin settings, blacklists, and logs will be permanently deleted when you deactivate the plugin.
