I customized the mails that are sent when a follow-up or a subscription is set by a user and wants to receive a mail about it.
I did this my manipulating the files in this folder: \core-service\standalone\configuration\template\system\communication
1. Is this the recommended way to do it or is there some other (better) way to do this?
2. Will these files be overwritten when I update the core-service?
Thank you for your feedback.
