Shamim's Plugins

You want to send same announcement to all users when they first registered? Or individual announcement?

If same announcement, Please create an announcement to all roles and send me id of that announcement. I will write some code for you.

You can use like unset( $groups[ 7930 ], $groups[ 2343 ], $groups[ 1209 ] );

Yes, you can use my above provided code to create a shortcode using do_shortcode

We can send a copy to any email address ( sent you code in my previous reply), but cannot change user “to” email address

Currently you will have to modify code to achieve this. In future i will try to add this option.

What information you want to show as checkbox and radio button?

You can create your own. Please see https://www.shamimsplugins.com/docs/front-end-pm-pro/getting-started-2/email-beautify/

1. Which one is not working? Incoming emails or out going emails? Or both?
2. How many users you have in a single message?

You want to show subject line as dropdown or add a new dropdown field?
