Συχνές Ερωτήσεις
-
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.
