Emails like new booking confirmation, reschedule and cancellation mails to the invitee and admin are customisable by overriding PHP templates. If you do not dabble with code, we recommend using the services of a PHP developer who has good knowledge in WordPress to do the customisations. The developer should copy the original desired templates from the plugin and place it in child theme folder and modify it based on your needs.

All email templates can be found in [WP Site root]/wp-content/plugins/wpcal/templates/emails folder.

header.php

footer.php

invitee_booking_new.php

invitee_booking_reschedule.php

invitee_booking_cancellation.php

invitee_booking_reminder.php

admin_booking_new.php

admin_booking_reschedule.php

admin_booking_cancellation.php

Make sure the 'Invitee notification type' option of the event type is set to 'Email'.

For example, in this article we are customising email template of invitee new booking confirmation email.

Locate the plugin's desired email template in wpcal plugin's templates folder. [WP Site root]/wp-content/plugins/wpcal/templates/

in this case the template that we are going to customise is emails/invitee_booking_new.php

Full path to the desired template file is [WP Site root]/wp-content/plugins/wpcal/templates/emails/invitee_booking_new.php

It is highly recommended to place the overriding (customised template) file inside a child theme so that it will not get removed during theme updates.

In our case, the child theme is twentytwentyone-child

Place the copied file in the child theme by creating a 'wpcal' folder as mentioned below

[WP Site root]/wp-content/themes/twentytwentyone-child/wpcal/emails/invitee_booking_new.php

To verify whether you have successfully overridden the template file, go to WP Admin › WPCal.io › Settings › General

Once your customised template displays in the list, you are all set to do the customisation.

Now you can customise the file [WP Site root]/wp-content/themes/twentytwentyone-child/wpcal/emails/invitee_booking_new.php. We strongly recommend you to do the email customisations in the staging site and once all changes are done and tested, deploy it to the production site.
