Sender Click Authorization for Contact Form 7

Protect your WordPress contact forms with sender verification.

Sender Click Authorization ensures every submission comes from a real email address by requiring the sender to click a verification link before the message is delivered. This simple step dramatically reduces spam, spoofed messages, and low-quality leads.

✨ Key Features

• Works with Contact Form 7 – seamlessly integrates without modifying your forms.
• Email Verification Step – holds the submission until the sender clicks the unique verification link.
• Pending Queue – review all unverified submissions in your WordPress dashboard.
• One-Click Actions – manually send, delete, or inspect submissions from the queue.
• Custom Templates – edit both the verification email and the post-submit message with placeholders.
• Blocked Domains – stop messages from your own domain or from disposable email services.
• Automatic Pruning – expired verifications are cleaned up automatically.
• Lightweight & Secure – built using WordPress standards, no third-party services required.
• Fully Translatable – ready for localization with .pot file included.

🛠️ Configuration Options

• Timeout Window – choose how many hours a verification link stays valid.
• Verification Email – plain-text template with placeholders for [your-name], [your-email], [verification_url], etc.

• Style Controls – set background and border colors for the post-submit notice.
• Domain Blocking – add/remove blocked domains directly from the settings screen.
