This plugin is intended to be useful more for developers than other types of users.
Have you ever had a client who likes to be able to independently update the content of the emails that your code is sending out programmatically? If so, this plugin might help you make your client happy.
How to use:
When you activate the plugin, it adds a custom post type to your website called “Email Templates”. You can create your templates using this custom post type. Templates can contain placeholders for your code to fill them up with desired values. A placeholder sample would be {USERNAME} or {USER_EMAIL}. Please note, placeholders should not contain lowercase letters.
This plugin creates a global instance of the BlueCube\Email_Template class which is called $bluecube_email_template. Once you have created a template, you can use the sendEmail() method of the instance to send out your emails.
<pre><code>$email_args = array(
 'template_title' => 'your-template-title',
 'to' => $email,
 'variables' => array('username' => 'JohnDoe', 'user_email' => 'test@test.com'),
);
$bluecube_email_template->sendEmail($email_args);
</code></pre>

<h3>External Services</h3>
This plugin’s core email-building functionality runs entirely on your own server. No data is transmitted to any third party during template creation, preview, or email sending.
The Pro license verification feature contacts an external API operated by CodePros AI (the plugin developer). This is the only external service this plugin uses.
