RelayPress is a WordPress plugin that adds a Mailrelay newsletter form with Cloudflare Turnstile, GDPR consent, double opt-in support, and audit logs.

Features

• Mailrelay API integration (active or inactive subscribers).
• Cloudflare Turnstile protection (as a core extension).
• GDPR consent checkbox and optional log retention.
• Neutral success message to avoid email enumeration.
• Shortcode, WordPress widget, and Elementor widget.
• Logs table with retention and manual purge.
• Extensions registry and admin screen for optional integrations.

Requirements

• PHP 8.1+
• WordPress 6.0+
• Mailrelay account with API token
• Cloudflare Turnstile keys (optional but recommended)

Installation (single site)

1. Download the ZIP from a GitHub Release.
2. WordPress -> Plugins -> Add New -> Upload Plugin -> Activate.
3. Settings -> RelayPress -> configure API and Turnstile.

Usage

Shortcode:

[relaypress_newsletter]

Widget:

• Appearance -> Widgets -> "RelayPress"

Elementor:

• Search for "RelayPress" in the widget panel.

Theme template override

You can override the frontend form by adding a template file in your theme:

• your-theme/relaypress-newsletter/form.php
• or your-theme/mr4wp/form.php

The plugin will load the first matching file and fall back to its own template at templates/form.php.

Configuration

Open Settings -> RelayPress and set:

• Mailrelay API base URL and token.
• Group IDs and subscriber status (active or inactive).
• Text labels and GDPR consent text.
• Log retention and rate limits.
• Enable AJAX submissions (optional).

Turnstile:

• Settings -> RelayPress -> Turnstile for site + secret keys.

Extensions:

• Settings -> RelayPress -> Extensions to enable or disable optional extensions.

Logs and GDPR

Logs are stored in a dedicated table. You can:

• Enable or disable log storage.
• Hash IPs instead of storing raw IPs.
• Purge logs automatically after the retention window.
• Purge logs manually from the settings page.

Local development

Install dev tools:

composer install

Create local PHPUnit config:

cp phpunit.xml.dist phpunit.xml

Run checks:

composer run phpcs
composer run phpstan
vendor/bin/phpunit

Build a local ZIP for testing

CI compiles MO files during release. To package locally, make sure you compile translations and then zip the plugin folder.

Compile translations (requires msgfmt):

msgfmt languages/relaypress-newsletter-es_ES.po -o languages/relaypress-newsletter-es_ES.mo

Create a ZIP from the plugin root (PowerShell example):

$zip = "relaypress.zip"
if (Test-Path $zip) { Remove-Item $zip }
Compress-Archive -Path * -DestinationPath $zip

Then upload relaypress.zip in WordPress -> Plugins -> Add New -> Upload Plugin.

Releases (GitFlow)

Branches:

• main: production
• develop: integration
• feature/*: development
• release/vX.Y.Z: release prep
• hotfix/vX.Y.Z: urgent fixes

To cut a release:

1. Merge feature work into develop.
2. Run the "Release (GitFlow)" workflow in GitHub Actions.
3. The workflow bumps versions, runs checks, opens PRs, tags vX.Y.Z, and creates a ZIP.

Translations

Translation files live in languages/. To update translations, regenerate the POT and build PO/MO files as needed.
