New line in body of an email when output is from an array

I load some information in from a file which is of the format

User1
User2
etc

using $Input = Get-Content "StaticUsers.txt"

At the end of my script I send an email with the body being sent to a number of users using

$body = "$Input" + "rn"

The issue is that the received email shows the list as the following

User1 User2 etc

instead of each item on a new line. How can I achieve this?

    Use the "-join" operator: 

    $Input = 1,2,3,4
$body = ($input -join [Environment]::NewLine) + [Environment]::NewLine

    You can substitute "rn" for "[Environment]::NewLine" if you like.

    Hello

    Thank you for your question and reaching out.

    The PowerShell newline indicator is n, and can only be used in double quotes. Single quotes will print the actual "n".

    For Example :
    $body = "first line" + "`n" + "second line"

    Also, One solution would be to use <br /> to break lines and specify the switch -BodyAsHtml so that body would be treated as html and email client would display it correctly, alternatie approach would be to use `n for line breaks and keep body as text.
