I don’t know if it’s possible to use do_shortcode() to call the email-download shortcode and get everything to work. It might work, might not. When the email-download shortcode executes, the EBD code looks at its arguments and it cares about the quotes when it goes to parse them. After parsing, it runs do_shortcode itself to get CF7 and/or Download Monitor to run.
At least at first glance, I would think you could get it to work if you properly escaped (backslashed) your quotes. At least for what you pasted in, it doesn’t look like you’re doing that, but it’s possibly that this support forum software removed your backslashes (not sure if it would do that or not). Anyway, I would start by putting backslashes before each quote used around the 455 an 459 arguments. If that doesn’t work, maybe try double-backslashes? Not sure .. you’ll just have to experiment.
