Protect your Contact Form 7 forms with GDPR-compliant Double Opt-In. Ensure valid emails, prevent fake signups, and stay compliant.

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

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:
<ol>
<li>Stores the submission in a secure database table.</li>
<li>Sends a confirmation email with a unique, time-limited link.</li>
<li>Only after the visitor clicks that link is the original form mail delivered.</li>
</ol>
This ensures:
<ul>
<li>Only valid, verified email addresses reach your inbox.</li>
<li>GDPR / DSGVO requirements are met with proper consent tracking, IP logging, and data retention.</li>
<li>Your database stays clean and reliable &#8212; no fake or mistyped addresses.</li>
</ul>
Out-of-the-box support for Contact Form 7. Additional form systems — Avada, Elementor, Gravity Forms, WPForms — are available as separate addon plugins.
<h4>How It Works</h4>
<ol>
<li>A visitor fills out your Contact Form 7 form and clicks submit.</li>
<li>The plugin intercepts the submission, stores the form data, and generates a unique hash.</li>
<li>A confirmation email is sent to the visitor&#8217;s email address containing a verification link.</li>
<li>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).</li>
<li>The confirmed opt-in is logged in the admin dashboard with timestamps and IP addresses for full GDPR compliance.</li>
</ol>

<h3>Privacy &amp; Telemetry</h3>
As of version 5.1.7 the plugin no longer transmits any telemetry. 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 &#8212; for instance to decide whether the plugin has been 
useful long enough to ask you for a review.
We never sell or share data.
<h4>GDPR / DSGVO Compliance</h4>
<ul>
<li>No personal data, no cookies, no user tracking.</li>
<li>Nothing is sent to any external server. Counters stay in your database and are 
removed when you uninstall the plugin.</li>
<li>The telemetry setting under Double Opt-In &gt; Settings is retained: should 
transmission ever be reintroduced, it will be honoured before anything is sent.</li>
</ul>
<h4>Bundled assets</h4>
The admin interface uses the Inter typeface. It is self-hosted &#8212; the font 
file is embedded in the plugin&#8217;s own admin bundle, so opening the plugin&#8217;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).
