How Do I Change the HTML for Email Templates?

Are you hoping to customize your registration confirmation email in WordPress using Registrations for the Events Calendar? This guide walks through how to create your own HTML templates so your confirmation messages match your brand.

Step‑by‑Step: Registration Confirmation Email Customization

  1. Access your theme folder
    Go to wp-content/themes/your-theme/ (replace your-theme with your active theme’s directory).
  2. Create the required folders
    Inside your theme, add this path: /rtec/email/. Your custom email templates will live here.
  3. Copy the plugin’s email template files
    From wp-content/plugins/registrations-for-the-events-calendar/templates/email/, copy:

    • confirmation-body.php
    • header-generic.php
    • footer-generic.php

    into your new rtec/email/ folder.

  4. Customize the HTML to match your brand
    Edit the copied files—adjust CSS, move placeholders around, add your logo, or wrap everything in responsive HTML. WordPress will automatically use these instead of the default plugin templates.

Here’s what your final structure should look like:

/wp-content/themes/your-theme/
└── rtec/
    └── email/
        ├── confirmation-body.php
        ├── header-generic.php
        └── footer-generic.php

Using a Child Theme (Recommended)

We recommend making these changes in a child theme instead of editing your main theme directly. This helps preserve your custom email templates even if you update your theme later.

If you’re not already using one, WordPress has a great guide on how to create a child theme here:

Once your child theme is active, follow the same folder structure inside it—/rtec/email/—to store and manage your custom email templates safely.
