WP Smart Consent adds a GDPR-compliant opt-in checkbox to WPForms. When a customer ticks it and submits a form, their details are automatically forwarded to Mailster in real time.

The connection explained
WP Smart Consent adds a GDPR-compliant opt-in checkbox to your form. It is unchecked by default, so the visitor must actively tick it to subscribe. When they do and submits a form, WP Smart Consent immediately captures the consent with a timestamp and stores it in your WordPress database, giving you a complete audit trail without any third-party dependency. In the same request, it adds the contact directly to Mailster inside your WordPress installation, with name, email, and any custom fields you have mapped. No data leaves your server. No cron delays. No code.
