Frequently Asked Questions

Common questions about Double Opt-In for Contact Form 7 – Secure, GDPR-Compliant Email Verification

When a visitor submits your form, the plugin stores the submission and sends a confirmation email with a unique link. The original form mail is only delivered after the visitor clicks that link. This verifies that the email address is valid and belongs to the person who filled out the form.

Yes. The plugin tracks all data required for GDPR compliance: consent text, registration and confirmation timestamps, IP addresses, and form data. It integrates with WordPress Privacy Tools for personal data export and erasure requests. You can configure automatic data retention and anonymization policies.

The free Core plugin supports Contact Form 7 out of the box. Support for Avada Forms, Elementor Pro Forms, WPForms, and Gravity Forms is available through separate paid addon plugins (install alongside Core).

If you configured Double Opt-In on an Avada form before Core 5.0, a one-time notice appears in your WordPress admin with a "Claim free Avada grandfather license" button. One click installs the paid Avada addon with a permanent free license bound to your site. Your existing setup continues working with zero configuration changes. The free claim window is open until October 2026.

Yes. The plugin includes a visual drag & drop email editor with block-based design. You can choose from pre-built template presets or create your own. Placeholders like [doubleoptinlink], [doubleoptin_form_date], and form field values are replaced automatically.

Unconfirmed opt-ins are stored in the database and can be cleaned up automatically. You can configure the retention period for unconfirmed entries in the settings (e.g. delete after 30 days). In the Pro version, you can also send automatic reminder emails.

Yes. In the per-form settings, you can select a Confirmation Page. The user will be redirected there after clicking the confirmation link.

Yes. The plugin automatically disables CAPTCHA validation (Google reCAPTCHA, hCaptcha, CF7 Captcha by Forge12) when re-sending the original form mail after confirmation. This prevents false spam detections during the confirmation step. CAPTCHA is re-enabled immediately after the mail has been sent.

Yes. Use the Conditions setting in the per-form configuration. Enter the name of a form field (e.g. a checkbox). Double Opt-In will only be triggered when that field has a value.

Legacy approach (WordPress hook): add_action( 'f12_cf7_doubleoptin_after_confirm', function( $hash, $optIn ) { $data = maybe_unserialize( $optIn->get_content() ); }, 10, 2 ); Modern approach (typed event, since 4.0): Use OptInConfirmedEvent via the EventDispatcher. The event provides getFormData(), getEmail(), getFormId(), and more. See docs/hooks-and-events.md for the complete reference.
