About MDO Lite
From the official readme · v1.0.5Description
MDO Lite adds a simple double opt-in workflow to Divi contact form modules. When a visitor submits a Divi contact form, the plugin:
- Sends a confirmation email with a secure link
- Forwards the original form message to you only after the visitor clicks the link
No WordPress user account is required for visitors.
Full version
Need Contact Form 7, experimental universal form support, or extended options? The full plugin MailDoubleOptin is available at plugins.froendhoff.com.
Privacy
MDO Lite does not connect to external servers. All pending confirmations are stored in your WordPress database. Confirmation emails are sent via your site’s own wp_mail() configuration.
Installation
- Upload the plugin folder to
/wp-content/plugins/mdo-lite/or install via the WordPress plugins screen. - Activate the plugin.
- Open Settings → MDO Lite and enable double opt-in for Divi forms.
- Make sure the Divi theme or Divi Builder is active.
Frequently asked questions
Does this work with Contact Form 7?
No. MDO Lite supports Divi contact forms only. Use the full version at plugins.froendhoff.com for CF7.
Does the plugin send data to third-party servers?
No. MDO Lite works entirely on your WordPress site.
How is form submission secured without WordPress nonces?
Divi contact forms are public front-end forms and do not include WordPress nonces. The plugin only reads POST data during an active Divi contact form submission, validates email addresses, and sanitizes all stored fields. Email confirmation uses a one-time random token in the link (GET request), not admin actions.
