Customizing Welcome Email in Nextcloud 30

Hello everyone,

I am currently running Nextcloud version 30 on Docker, and I’ve successfully configured SMTP for sending emails. The welcome email feature is working well, but I would like to customize the content of the welcome email.

Specifically, I want to:

  1. Modify the text of the welcome email.
  2. Attach a document to the welcome email.

Could anyone guide me on how to achieve this? Any insights or steps would be greatly appreciated!

Thank you!
