JSON Formatting - mailto - cc address isn't working

Question

I'm trying to include a cc address for my item list email link.

I used this:

 "href": {
      "operator": "+",
      "operands": [
        "mailto:",
        "[email protected]",
        "?cc=",
        "[email protected]",
        "?subject=",
        "Test Subject",

The result is the following:

For some reason my subject lengthens the cc field. Any idea what goes wrong here?

If I look at the code I don't see anything wrong.

Answer 1

Use & instead of ? before subject like:

"href": {
      "operator": "+",
      "operands": [
        "mailto:",
        "[email protected]",
        "?cc=",
        "[email protected]",
        "&subject=",
        "Test Subject",

Example mailto format including CC, BCC, Subject and Body:

mailto:[email protected][email protected]&[email protected]&subject=Email Subject Text&body=Message Content
