Layout checkbox-group layout in email

Good morning

For example, I have 10 checkboxen in my form.

When the visitor submits the form, my generated email looks like this for the check-box group:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10

Is there any possibility I can get an generated email with a layout like this:
1
2
3
4
5
6
7
8
9
10


Thanks in advance

ps: I tried to search the forums, but the website keeps giving me an "505 bad gateway" error.
So now I have the chance, I just make a topic

Hi CODA-gfx ,

You can use PHP in a Custom Code action to replace the ', ' list separator with '<br />'
