Array list displaying brackets and quotes around array items in email

[cpuser]

Hi, I am using a server action to create an array list to imbed into an email to auto send on order creation.
However after following the great tutorial on working with arrays, I get brackets and quotation marks around the names in the array embedded in the email, e.g.
[{“packages”:" Package B"},

and the plain text email. contains the brackets around the package names that were ordered

Make sure of:

1. Add the repeat value in your array list

2. Use the Join formatter to place the packages in your content of the send email step
