Paubox CF7 Integration WP Registry grade A. No security issues foundWP RegistryNo security issues foundOpen the reportA

WordPress plugin that routes Contact Form 7 submissions through the Paubox encrypted email API, so form emails are delivered HIPAA-compliant instead of through the site's regular mail transport.

📢 Trademark Notice: This plugin integrates Contact Form 7 with the Paubox encrypted email API. "Paubox" is a trademark of Paubox, Inc. "Contact Form 7" is a trademark of Rock Lobster, LLC. This plugin is an independent integration and is not affiliated with, endorsed by, or sponsored by Paubox, Inc. or the Contact Form 7 project / Rock Lobster, LLC. We use "CF7" (an unofficial abbreviated form) in our plugin name in compliance with the Contact Form 7 trademark policy.

Features

• 🔒 Encrypted Delivery: Sends Contact Form 7 emails through the Paubox API instead of wp_mail(), so submissions are HIPAA-compliant encrypted in transit
• 🧩 Per-Form Configuration: Adds a "Paubox Integration" tab to the Contact Form 7 editor — enable Paubox delivery, and configure From, Recipient, Subject, and Message body independently per form
• 🏷️ Mail-Tag Support: Recipient, subject, and message body fields accept CF7 mail-tags ([your-name], [your-email], etc.), resolved from the actual submission
• 📎 Attachment Support: Forwards uploaded files referenced in the message template as base64-encoded attachments in the API payload
• ⚙️ Centralized Credentials: API key and API user are configured once, via Silver Assist Settings Hub (or a standalone settings page when the hub isn't installed) — no per-form credential duplication
• 🔄 Automatic Updates: Built-in GitHub-based update system via silverassist/wp-github-updater
• 🛡️ Fails Safe: Contact Form 7 must be active for any of this plugin's components to load; without valid API credentials, send_mail() returns a WP_Error rather than silently dropping the submission
• 📊 Delivery Log: A "Recent Deliveries" table on the settings page lists the most recent Paubox send attempts (form, status, HTTP code, error) for at-a-glance debugging — metadata only, never the email body or attachments

Requirements

• WordPress 6.5 or higher
• PHP 8.2 or higher
• Contact Form 7 (required — this plugin does nothing without it)
• A Paubox account with API credentials

Installation

Method 1: WordPress Admin Dashboard (Recommended)

1. Download the latest paubox-cf7-v{version}.zip from the Releases page
2. In WordPress admin, go to Plugins → Add New → Upload Plugin
3. Choose the downloaded ZIP and click Install Now
4. Click Activate Plugin

Method 2: Manual Installation via FTP

Usage

Open any Contact Form 7 form in the editor and switch to the new Paubox Integration tab:

On submission, the plugin builds the message from the template, resolves attachments, and sends it through the Paubox API instead of Contact Form 7's default mailer.

Automatic Updates

The plugin checks this GitHub repository for new releases and can update itself directly from the WordPress admin, with no separate configuration required — see the Check Updates button next to the plugin's Settings Hub entry.

Development

composer install
composer phpcs      # Coding standards
composer phpstan     # Static analysis (level 8)
composer test        # Unit tests
composer test:integration  # Integration tests (requires the WP test suite)

composer install also points Git at .githooks/ (core.hooksPath), which strips any AI attribution trailer (Co-Authored-By: Claude ..., etc.) from commit messages — commits in this repo are authored solely by the human.
