Double Opt-In for CF7 is a WordPress plugin designed to enhance the Contact Form 7 plugin by adding double opt-in functionality to form submissions. This feature requires submitters to confirm their identity via a confirmation email, significantly improving data security and compliance with GDPR. The plugin also supports translation and can be easily integrated with existing CF7 forms with a one-click conversion feature. Additionally, it automatically creates an opt-in page and allows for customizable email templates, enhancing user experience and accessibility.

The plugin requires the installation of Contact Form 7 along with either Flamingo or Contact Form 7 Database Addon – CFDB7 to function properly. Additional features include custom file upload inputs, specific validation errors for form elements, and options to alter CSV export settings. By implementing double opt-in, users can reduce spam and ensure they have proper consent for data processing, making it a valuable addition for sites that prioritize user data protection.
