Powershell RDS CAL email Report

Question

I have a PowerShell command that gives me how many CALs I have installed and how many are used.  I want to change the write-host to a variable so that I can add it to a mail.

This is what I have :

$fileName = (Invoke-WmiMethod Win32_TSLicenseReport -Name GenerateReportEx).FileName
$summaryEntries = (Get-WmiObject Win32_TSLicenseReport|Where-Object FileName -eq $fileName).FetchReportSummaryEntries(0,0).ReportSummaryEntries
$summaryEntries|ForEach {Write-Host $_.ProductVersion $_.TSCALType "Installed:" $_.InstalledLicenses "Issued:" $_.IssuedLicenses}

$EmailTo = "itgroup@contonso.com"
$EmailFrom = "admin@contonso.com"
$user = 'admin@contonso.com'
$password = Unprotect-CmsMessage -Path C:\Scripts\Powershell\EncryptedSecret.txt
$Subject = "Alert: CAL USAGE "
$Body = "Alert; $Report"
$SMTPServer = "smtp@contonso.com"
$SMTPMessage = New-Object System.Net.Mail.MailMessage($EmailFrom,$EmailTo,$Subject,$Body)
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, 25)
$SMTPClient.EnableSsl = $false
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential($user, $password)
$SMTPClient.Send($SMTPMessage)

I have used both parts of this script separately, but I would like to join them together, to make them more useful.
