email submission content

Hi,

I’m trying to send a notification email after filling a form. I’m using shortcodes to write the email’s content. But after reviewing the email. The data just appears as “Array”. Does anyone knows how can I extract the array data to fill the email correctly?

Example:
—————————————————- beginning of email
Hello world,

This is an email from [user_first].

Here is a list of this user capabilities:

Array <- [user_list]

regards,

[user_first]
—————————————————– end of email
