PopUp Compose email form on save

Is it possible to popup email composition form (suite editor) when a user saves some item.
I now that I can make scheduler to send email on some action but I don’t wont it implemented like that.
Actually I want user to intervene on the email body entering some additional date when needed.

So use case would be like this:
When sales guy changes sales stage to Close-Won and saves opportunity I want to display a popup email compose form prepopulated based on template.
Then he checks if any additional info should be entered and sends email afterwards.

How can it be done?
