How to override templates in your child theme
If you want to customize the various templates in Groundhogg you can do so by defining a groundhogg-templates
folder in your child theme and overriding any template files there.
Your child theme directory may look like this if you wanted to replace the email header template.
Theme Folder - groudhogg-templates - emails - header-default.php
You can download this repository template (either from Github or using a tool like download-directory) into your child theme to start making modifications to the Groundhogg templates.
<?php $unsub_link = apply_filters( 'groundhogg/email_template/unsubscribe_link', home_url() ); ?> <a href="<?php echo esc_url( $unsub_link ); ?>">Unsubscribe</a>
