WordPress + Transactional
Replace the unreliable default WordPress mail function with Transactional. The official WordPress plugin overrides wp_mail() so that every email your WordPress site sends, from password resets to plugin notifications, goes through Transactional high-deliverability infrastructure.
OVERVIEW
Replace the unreliable default WordPress mail function with Transactional. The official WordPress plugin overrides wp_mail() so that every email your WordPress site sends, from password resets to plugin notifications, goes through Transactional high-deliverability infrastructure.
Integration Workflow
A step-by-step look at how data flows between your tools and Transactional.
WordPress Triggers Email
A user resets their password, a form is submitted, or a plugin sends an email.
wp_mail() Intercepted
The Transactional plugin intercepts the wp_mail call.
API Delivery
The email is sent through the Transactional API with full tracking enabled.
Logged & Tracked
Delivery status, opens, and clicks are tracked and visible in your dashboard.
What You Get
Everything you need to integrate WordPress with Transactional.
One-Click Setup
Install the plugin, enter your API key, and every WordPress email immediately routes through Transactional.
Email Log
View a log of every email sent from your WordPress site with delivery status and engagement data.
Plugin Compatible
Works with Contact Form 7, WooCommerce, Gravity Forms, and any plugin that uses wp_mail().
Fallback Support
If the API is unreachable, the plugin falls back to default WordPress mail to ensure no email is lost.
Get Started in Minutes
Here is a code example showing how to connect WordPress with Transactional.
<?php
// WordPress Plugin Configuration
// Add to wp-config.php or configure via admin panel
define('TRANSACTIONAL_API_KEY', 'txl_your_api_key');
define('TRANSACTIONAL_FROM_EMAIL', 'hello@yoursite.com');
define('TRANSACTIONAL_FROM_NAME', 'Your Site');
// The plugin automatically overrides wp_mail()
// Example: this now sends via Transactional
wp_mail(
'user@example.com',
'Password Reset',
'Click here to reset your password...',
['Content-Type: text/html; charset=UTF-8']
);
// You can also use the Transactional API directly
$transactional = new Transactional\Client('txl_your_api_key');
$transactional->send([
'from' => 'hello@yoursite.com',
'to' => 'user@example.com',
'subject' => 'Welcome!',
'html' => '<h1>Welcome to our site</h1>',
'tag' => 'wordpress-welcome',
