From your question, do you have multiple page registration sources?
Yes.
I have multiple registration pages and the roles assigned to them vary.
If I'm sending an email when registering, I think you can do it by customizing the Registration Web Part.
However, this time it will be difficult because it is an email when the administrator approves.
I noticed now.
Email templates can use if statements to control what is sent by macros, right?
I feel like I can solve it.
