PowerShell to send email - powershell

Question

I am running a Task Scheduler to execute my PowerShell every 30 minutes.
So
$users = Search-ADAccount -LockedOut -SearchBase
"OU=People,DC=Example,DC=com" -SearchScope Subtree | Select
SamAccountName
This returns a list of users. Now I want to create an emailbody with the users
$EmailBody = ForEach($user in $users) {"`r`n",$user}
Send-MailMessage -To $to -Subject "Locked Accounts" -BodyAsHtml $EmailBody -From $from -Credential $cred -SmtpServer $server -Debug
However my current code will send the email even if NO ONE is locked. Is there anyway I can check to see if the $users has at least 1 person?
(I haven't tested the $EmailBody but would like to know if this is acceptable for BodyAsHtml)
================
Updated Code
if ($users) {
if ($users.count -gt 0) {#even if there are users, this line always is false.
# send the email here
foreach($user in $users)
{
$message = $message + " " + $user + " is locked out" + "`r`n"
Write-Host $user
}
Send-MailMessage -To $to -Subject "Locked Accounts" -BodyAsHtml $message -From $from -Credential $cred -SmtpServer $server -Debug
} }

Answer 1

if ($users -ne $null) # lists can be empty as well, in which case the count fails
{
if ($users.count -gt 0) {
# send the email here
}
}
