Double Opt-In for Contact Form 7 – Secure, GDPR-Compliant vs ReCaptcha v2 for Contact Form 7

Double Opt-In adds a mandatory email verification step to your Contact Form 7 forms. When a visitor submits your form, the original mail is not sent immediately. Instead, the plugin: Stores the submission in a secure database table. Sends a confirmation email with a unique, time-limited link. Only after the visitor clicks that link is the original form mail delivered. This ensures: Only valid, verified email addresses reach your inbox. GDPR / DSGVO requirements are met with proper consent tracking, IP logging, and data retention. Your database stays clean and reliable — no fake or mistyped addresses. Out-of-the-box support for Contact Form 7. Additional form systems — Avada, Elementor, Gravity Forms, WPForms — are available as separate addon plugins. How It Works A visitor fills out your Contact Form 7 form and clicks submit. The plugin intercepts the submission, stores the form data, and generates a unique hash. A confirmation email is sent to the visitor’s email address containing a verification link. The visitor clicks the link. The plugin verifies the hash, marks the opt-in as confirmed, and sends the original form mail (as if the form was just submitted). The confirmed opt-in is logged in the admin dashboard with timestamps and IP addresses for full GDPR compliance.

The daily job that used to send a usage snapshot has been removed, and an update also removes it from the WP-Cron schedule of sites that already had it. Usage counters (how many opt-ins were confirmed, for example) are still kept, but they never leave the site. They are stored in a single WordPress option and are used only in the admin — for instance to decide whether the plugin has been useful long enough to ask you for a review. We never sell or share data. GDPR / DSGVO Compliance No personal data, no cookies, no user tracking. Nothing is sent to any external server. Counters stay in your database and are removed when you uninstall the plugin. The telemetry setting under Double Opt-In > Settings is retained: should transmission ever be reintroduced, it will be honoured before anything is sent. Bundled assets The admin interface uses the Inter typeface. It is self-hosted — the font file is embedded in the plugin’s own admin bundle, so opening the plugin’s screens does not contact Google Fonts or any other third party. Inter is licensed under the SIL Open Font License 1.1 (see licenses/inter-OFL-1.1.txt).

Contact Form 7 v5.1 dropped support for reCaptcha v2 along with the [recaptcha] tag December 2018. This plugin brings that functionality back from Contact Form 7 5.0.5 and re-adds the [recaptcha] tag. If this plugin is installed before updating Contact Form 7 from v5.0.5 to v5.1.1 then it will carry over your old API keys. At that point you will just need to head to this plugins settings page to tell the website to use reCaptcha v2. Once installed and configured it should be the same reCaptcha functionality you are used to in previous versions of Contact Form 7. IQComputing Like us on Facebook Follow us on Twitter Fork on Github
