常见问题:
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.
