## FAQ

### Does this plugin require Contact Form 7?

Yes. This plugin is specifically built for Contact Form 7 and requires it to be 
installed and active.

### How does the email verification work?

When a user submits a form, the plugin validates the email, checks it against stored
submissions, and prevents the submission if the email was used before.

### Will the plugin delete stored emails on uninstall?

Yes. If the user uninstalls the plugin (not just deactivates), the plugin removes
its custom database table and options.
